Post-lesson quizzes: where to cut

Grades 3, 4 and 5 · every lesson quiz read by a reviewer who was not its author · nothing changed yet · 14 October 2026

Decisions I need from you

Which shape do the Grades 3–5 lesson quizzes take?

Shape A, your words this afternoon for these grades: average near five; the really obvious lessons two or three; the complicated ones more, capped at ten. The readers applied it lesson by lesson (obvious 2–3, one-step 4–6, routine 5–8, complex up to 10) and chose which items stay.

What A does: 5201 questions now → 3100 (40% cut); average 10.1 → 6.0 per lesson; lessons above ten go from 173 to 0. The average sits above five because almost every lesson keeps a trap, a term pair and, where the routine has steps, its scaffold run.

Shape B, the rule you gave the middle-school courses the same afternoon (14 Oct, MS Physics Topic 1): at most five questions, an easy lesson two or three, the rest kept in a reserve. Applied here on top of the readers' keeps it would give about 2522 questions, average 4.9 (an estimate: which five is a second pass). Your note scoped that rule to grades 6–8 and left grades 3–5 on the 29 Sep ruling until you said otherwise.

My recommendation: Shape A for grades 3–5. Younger children need the fluency repetition more than older ones, the readers' keeps already remove the repeats you named, and a hard five would cut scaffold runs on measuring and reading routines that an eight-year-old still needs.

Where do the cut questions go?

Each cut item is either a clean four-option question that stands on its own, or a two- or three-option or figure-bound item that only made sense inside its quiz.

48 of the 2101 cut items are clean four-option questions a PP100 bank could take as they stand; the rest are fluency repeats.

The middle-school rule keeps cut items verbatim in a reserve beside the lesson, where the practice set and the bank can draw on them; nothing is deleted.

My recommendation: The same reserve here: every cut item moves to a reserve list in its lesson, the clean four-option ones also offered to a short bank. Nothing is deleted and any item is one line to restore.

Does the checker enforce the shape you pick, for new quizzes from today?

Today the Grades 3–5 checker has no view on quiz length; the middle-school checker fails a quiz above five since this afternoon.

Shape A would FAIL above ten and WARN above six on a lesson marked obvious or one-step; Shape B would FAIL above five. Existing quizzes are trimmed by the pass above, not by the checker.

My recommendation: Yes, matching whichever shape you pick in the first card.

Applied without asking: the one question attached to each video (the XP gate) is outside this count and is not touched; the mixed practice set and the PP100 are not touched; the readers kept every misconception trap, term recall, boundary case and scaffold run on a multi-step routine.

The plot in five lines

514 lessons, 5201 questions after them. Average 10.1 per lesson; the readers propose 6.0.

Grade 3: 197 lessons, average 10.8 → 5.9; 100 lessons above ten now, 0 after; every quiz loses at least one item.

Grade 4: 163 lessons, average 10.4 → 6.2; 63 lessons above ten now, 0 after; every quiz loses at least one item.

Grade 5: 154 lessons, average 9.0 → 5.9; 10 lessons above ten now, 0 after; every quiz loses at least one item.

What the waste is: same options, new instance (803 items); same sort repeated (407 items).

Examples: what a cut looks like

Each reader picked the clearest cases in its slice, and one quiz it kept long. Stems are quoted as the student sees them.

Grade 3 · G3T05 L01 — What a force is

19 items; seven are the same 'is this a force?' yes/no with a new scene each, two more re-ask Topics 3 and 4, and the definition is asked twice

Keep: items 3, 5, 6, 7, 10, 16, 18, 19 (19 → 8)

Why: the definition recognised once, one item per named force (magnetic force, weight, contact force), the staring boundary, the only-hands trap, recognition then typed 'force'; 11 items go

Grade 3 · G3T01 L03 — Say how far and which way

15 items cut to 8, but the scaffold run and both coined terms stay

Keep: items 3, 4, 5, 10, 12, 13, 14, 15 (15 → 8)

Why: a three-step routine coining two terms: the scaffold pair (how many steps, which way) stays as a run, one bare EXACTLY item, one distance-AND-direction item, recognition then typed recall for both distance and direction; the paired duplicates (6, 11) and the re-tests of L02 go

Grade 3 · G3T02 L08 — Slowing down

14 items; twelve are 'is it slowing down?' yes/no, six of them the same three-numbers pattern

Keep: items 3, 4, 6, 10, 11 (14 → 5)

Why: one numbers yes, one drawn yes, one drawn no, one steady no, and the slow-but-steady turtle (the case a child gets wrong); the two opening recalls re-test L05 and L07

Grade 3 · G3T01 L06 — Straight or curved path

14 items; eleven are 'straight or curved?' on a dotted line with a new mover each

Keep: items 1, 3, 5, 12, 13, 14 (14 → 6)

Why: one straight on the ground, one arc, the zip line (straight through the air - the near-miss), the circle trap, recognition then typed 'path'

Grade 4 · G4T08 L02 — Spot the taller wave

Five identical compares and two term recalls for one comparative word

Keep: items 1, 2, 5 (top / same / bottom), 6 (the arrow), 7 (tops-closer confusion), 9 (one term recall) (10 → 6)

Why: Three compares give one key per outcome; the fourth and fifth are the same decision on a new drawing. Items 9 and 10 both recall the term. L03 (wavelength) is the mirror image and gets the same cut.

Grade 4 · G4T09 L02 — Will the bulb light?

Five "Look at the drawing. Will the bulb light?" in a row

Keep: items 1, 2 (one each way), 6, 7 (where is the gap), 8, 9, 10 (10 → 7)

Why: The lesson's skill is to follow the loop and find the gap; the where-is-the-gap items test that. After one lights and one does not, the third, fourth and fifth yes/no drawings are repetition only.

Grade 4 · G4T07 L01 — High pitched or low pitched?

Seven high/low sorts a child does without the lesson

Keep: items 1, 7 (loud but low), 9 (quiet but high), 8 and 10 (the term, MCQ then typed) (10 → 5)

Why: High or low is known before the lesson; what the lesson adds is that pitch is not loudness. The two near-miss items carry that, so five obvious sorts go.

Grade 4 · G4T02 L02 — The one thing you change

Seven "What is the one thing X changes on purpose?" on seven described tests

Keep: items 2, 3, 4 (three instances keyed B, A, C), 9 (the question-form case), 10 (the misconception) (10 → 5)

Why: One decision; three instances are fluency, seven are padding. The same shape runs through Topic 2 L03, L04 and L05.

Grade 5 · G5T04 L04 — Non-contact forces

Thirteen items for one capstone: the contact / non-contact sort runs four times after the forces have each been named once

Keep: items 1, 2, 3, 4, 7, 9, 11, 13 (13 → 8)

Why: Items 1–3 already name each force once; one contact case (9) and the hard non-contact case (11, weight) are the fluency the two-way sort needs. Items 5 and 8 test Grade 3 magnetism and Topic 1's universal pull, not this atom.

Grade 5 · G5T10 L02 — New substance, or just a mixture?

Eleven yes/no items on one frame, three of them the dissolved-sugar no-case in different clothes

Keep: items 2, 4, 6, 7, 8, 11 (11 → 6)

Why: The belief item (7) carries the dissolving no-case; the ink item (4) is the boundary worth keeping (a colour that is not a new substance). Item 1 says "no sign appears" in its own stem.

Grade 5 · G5T06 L03 — Where a circuit's energy ends up

Three opening items a child answers without the lesson

Keep: items 4, 5, 7, 8, 9, 10 (10 → 6)

Why: A buzzer buzzes and a heater heats; the stem of item 2 says the train rolls. The lesson's work is the carrier, the chain, the bulb-is-warm why and the no-light-means-broken belief.

Grade 5 · G5T09 L02 — Melted or dissolved?

A seven-item melted/dissolved run where four melt cases say the same thing

Keep: items 1, 2, 4, 6, 8, 9, 10 (10 → 7)

Why: Two per class is the fluency a language sort needs; the snowman (3) also hands over the ice-cube belief item that follows it.

Grade 3 · G3T10 L02 — Unbalanced forces can make something slow down

KEPT LONG: 12 items cut only to 8 - slowing down carries three different misconceptions and a what-then-why pair

Keep: items 1, 2, 4, 6, 7, 8, 10, 11 (12 → 8)

Why: each keep does a different job: brakes, a drawn case, grass drag with nothing pushing forward, which force is stronger, the thrown ball slowing on the way up as what then why, the needs-a-push trap, the drag-makes-it-speed-up trap; only the three re-dressed drawn cases and the rule-as-true-claim go

Grade 3 · G3T20 L06 — Solid, liquid or gas? Sort the sample

Kept long on purpose: the solid/liquid/gas capstone keeps 8 of 13 because the awkward cases are the lesson

Keep: items 1, 2, 3, 4, 8, 10, 11, 13 (13 → 8)

Why: sugar, honey, air, the sand trap, fog, the sponge trap, which-clue-tells and the closed-box boundary each test a different decision; only the plain repeats (glue, cream, soda gas, milk, a second sponge) go

Grade 3 · G3T39 L01 — A stem grows toward the light

Kept long: 13 items down only to 8, because the quiz asks eight different things about one rule

Keep: items 1, 2, 4, 7, 8, 9, 10, 11 (13 → 8)

Why: direction from the side, from a box hole, after the pot is turned, light from above, the days timescale, grew-not-pushed, reading the light's side back from the lean, and turned-versus-grew are eight different moves; only the five items that restate one of them as a claim or a typed word go

Grade 4 · G4T22 L02 — How the shaking spreads out as waves

Kept long: a mechanism with three live misconceptions

Keep: items 2, 4, 5, 6, 7, 9, 10, 11, 12 (9 of 14) (14 → 9)

Why: The slip, the waves through the crust, weaker with distance, the seismograph read and the boat transfer are each a different step of the mechanism, and the two beliefs (ground slides; earthquakes are elsewhere) are distinct. Only the mirrored map, the duplicated beliefs and the Grade 3 ripples recall come out.

Grade 4 · G4T32 L05 — Why the Moon's shape seems to change

Kept long on purpose: why the Moon's shape seems to change (nine of eleven)

Keep: items 3-11; only the two Grade 3 recalls (the Moon makes no light; the Moon goes around Earth) go (11 → 9)

Why: This is a mechanism with a documented wrong cause (Earth's shadow). The lit half under three shapes, the why, the trap met twice in different clothes, two flashlight geometries and the month-long why each ask a different step of the model; none is the previous item with a noun changed. Nine honest items is what the skill has.

Grade 5 · G5T05 L03 — Trace the energy, step by step

Kept long on purpose: the three-step energy trace keeps its whole scaffold run

Keep: items 1, 2, 3, 4, 5, 8, 9, 10 (eight) (10 → 8)

Why: Source → type → carrier → where it ends up is a multi-step routine, so the four scaffold steps on one toy stay, then the order item, the pick-the-trace and the missing-step items. Only the two repeated blank-box items go.

Grade 5 · G5T14 L03 — The wind from the warm ocean brings humid air, clouds and rain

Kept long on purpose: the ocean-to-rain chain, eight items

Keep: items 1, 3, 4, 5, 6, 7, 9, 10 (10 → 8)

Why: A four-link mechanism: each link, the ordering, a prediction for wind off the ocean and one for wind off the land, a two-day transfer and the explain each do different work. Only the Topic 13 definition (item 2) and the Sun's-role repeat (item 8) go.

Grade 5 · G5T26 L03 — Trace the ripple through the web, link by link

Kept long: a multi-link ripple keeps its scaffold run

Keep: items 1, 2, 3, 4, 6, 8, 9 (7 of 9) (9 → 7)

Why: Tracing two or three links is a multi-step routine, so the worked → scaffolded → bare run stays whole; only the second and third bare two-link items go. Contrast L02 (one step: same way or opposite way), where the run collapses to one scaffold plus bare items.

32 more examples from the readers

Grade 3 · G3T03 L05 — Earth pulls on every part of you

14 items; three open with 'does Earth pull on your shoulders / fingers / teeth?' and six true-or-false items restate the same claim

  • Does Earth pull on your shoulders?
  • Does Earth pull on your fingers?
  • Does gravity pull on your teeth?
  • True or false: Earth pulls on your ears.
  • True or false: Earth pulls on your hands only when they touch the ground.
  • True or false: Earth pulls only on your feet.

Keep: items 5, 6, 7, 8, 14 (14 → 5)

Why: the what (hanging hair), the why (the monkey's arms), the only-the-touching-part trap, the cat's tail transfer, the raised hand; everything else is a yes a child gives before the lesson

Grade 3 · G3T25 L02 — A defense holds back what the weather brings

14 items; the lightning rod is asked three ways (items 4, 6, 7), and items 11-12 are items 2 and 1 asked backwards

  • A metal rod stands on the roof of a school, with a wire running down to the ground. What does the rod keep away from the roof?
  • Solomon says the lightning rod on his barn gives lightning a safe path down to the ground. Is Solomon right?
  • Lightning strikes Tallulah's tall barn most summers. She puts a metal rod on the roof … Will the rod keep the roof from catching fire?

Keep: items 1, 2, 3, 4, 5, 8, 14 (14 → 7)

Why: one defence per kind of weather, the levee-against-wind mismatch, 'defense' recognised and typed

Grade 3 · G3T42 L03 — What living things do when winter comes

14 items; items 1-3 and 4-9 are the same three-way sort asked twice in two wordings

  • Every fall, ducks fly south … Which word is for traveling to another place when the season changes?
  • In fall, monarch butterflies fly thousands of miles south … What do the monarchs do when winter comes?
  • Swallows leave a farm in September and fly far to the south … What do the swallows do when winter comes?
  • A lilac bush has dropped its leaves … Which word is for a plant like this?
  • In fall, an apple tree drops all its leaves … What does the apple tree do when winter comes?

Keep: items 1, 2, 3, 10, 12, 13, 14 (14 → 7)

Why: one recognition per coined class, the bare-tree-is-alive boundary, the fox that stays active, two typed terms

Grade 3 · G3T36 L01 — Egg-layers, or babies born alive

14 items; nine are 'X is a <group>. How does X make more Xs?' over one two-option set, then three term items on one word

  • A parrot is a bird. How does a parrot make more parrots?
  • A horse is a mammal. How does a horse make more horses?
  • A raccoon is a mammal. How does a raccoon make more raccoons?
  • A ladybug is an insect. How does a ladybug make more ladybugs?
  • A turtle lays eggs on a beach … What do we call an animal that lays eggs?

Keep: items 1, 2, 3, 4, 5, 6, 14 (14 → 7)

Why: one item per vertebrate group (bird, reptile, fish lay eggs; horse and manatee are born alive), the only-birds-lay-eggs trap, one recall

Grade 3 · G3T35 L01 — What makes an animal a mammal

12 items (and L02-L05 are built the same way); seven are 'is X a <group>?' over yes/no, plus a three-way pick a child answers from the animal's name

  • A hamster has soft fur, and a hamster mother feeds her babies milk. Is the hamster a mammal?
  • A hummingbird has feathers, and it hatches from an egg. Is the hummingbird a mammal?
  • A crocodile has dry, scaly skin, and it hatches from an egg. Is the crocodile a mammal?
  • Which of these three animals is a mammal? (a fish / a heron / a squirrel)
  • A cow has short hair, and a cow mother feeds her calf milk. Which group is the cow in?

Keep: items 1, 2, 3, 6, 10, 12 (12 → 6)

Why: the elephant with few hairs, one no, the swimming sea lion, which feature tells you, the beaver-is-a-fish trap, the recall; the same cut pattern takes each of the five group lessons from 11-13 items to 6-7

Grade 3 · G3T19 L01 — Does it sink or float?

11 items; nine are 'Look at the tank. Does the X sink or float?' with the tank drawn - the child reads the answer off the picture

  • Look at the tank. Does the apple sink or float?
  • Look at the tank. Does the marble sink or float?
  • Look at the tank. Does the brick sink or float?
  • Look at the tank. Does the potato sink or float?

Keep: items 2, 4, 6, 7, 10 (11 → 5)

Why: one sinks, the big-things-sink trap, the test routine, the mostly-under orange boundary, writing 'floats' in the table

Grade 3 · G3T33 L02 — Every living thing needs water

11 items; nine are 'does X need water?' yes/no with a new thing each time

  • A frog sits by a pond. Does the frog need water to stay alive?
  • A plastic bucket stands in the yard all summer. Does the bucket need water?
  • A wooden spoon lies in a drawer. Does the spoon need water?
  • A wheelbarrow stands out in the rain. Does the wheelbarrow need water?
  • An earthworm lives in damp soil. Does the worm need water?

Keep: items 2, 3, 4, 6, 10 (11 → 5)

Why: the desert lizard (the surprising yes), one non-living no, the bighorn-sheep trap, the tree, the drooping mint as evidence

Grade 3 · G3T17 L06 — Pick the right measuring tool

10 items on one fixed option set; every stem is 'X wants to know Y. Which tool does she use?' - each tool is asked two or three times

  • Yuki wants to know how cold the pond water is. Which tool does she use?
  • Kian wants to know how warm his bath water is. Which tool does he use?
  • Chloe wants to know how warm the water in a cup is. Which tool does she use?
  • Zain wants to know the mass of his backpack. Which tool does he use?

Keep: items 1, 2, 3, 4, 5 (10 → 5)

Why: one per tool plus the rain-water-in-a-cup transfer; the five cuts are clean four-option MCQs that could go to the bank

Grade 3 · G3T28 L02 — A natural resource can run short

9 items; four number pairs run the one faster-or-slower decision, and the rule is asked twice

  • People catch 30 fish from the lake each week. 10 new fish grow big each week. Do the fish run short?
  • People catch 25 fish from the river each week, and 10 new fish grow big. Nuala says the river's fish will run short. Is Nuala right?
  • People cut 8 trees from this wood each year. 8 new trees grow big each year. Do the trees run short?
  • Pickers take 40 baskets of berries … The bushes grow 40 baskets of new berries each summer. Do the berries run short?
  • Why does the oil under the ground run short?

Keep: items 1, 2, 4, 7, 9 (9 → 5)

Why: one faster, one equal, one slower, the nature-makes-none case, the rule line last

Grade 3 · G3T17 L01 — What is one mark worth?

L01 and L01b together put 20 items on one atom (SR3-P01); 15 of them are 'Here are the marks between A and B … What is one mark worth?'

  • Here are the marks between 40 and 50 on a thermometer. What is one mark worth?
  • Here are the marks between 80 and 90 on a thermometer. What is one mark worth? Type the number.
  • Here are the marks between 90 and 100 on a thermometer. What is one mark worth? Type the number.
  • Here are the marks between 30 and 40 on a ruler … / … between 30 and 40 on a measuring tool …

Keep: L01 items 1, 2, 3, 4, 9, 10; L01b items 1, 3, 4, 5, 9, 10 (10 → 6)

Why: three MCQ worths and one typed in L01, one stretch per tool in L01b, both traps, both from-words items; 20 becomes 12

Grade 3 · G3T21 L05b — Boiling or evaporating?

Boiling-or-evaporating carries four term items (two MCQ, two typed) on words already coined and typed in L03 and L05 of the same topic

  • Water in a pot of corn on the stove has bubbles all through it and turns into water vapor fast. What is that change called?
  • Water in a soup pot on the stove bubbles all through and turns into water vapor fast. What is that change called? Type the word.
  • Water goes into the air slowly from the top of a wet porch step, with no bubbles. What is that change called? Type the word.

Keep: items 1, 3, 4, 5, 8 (10 → 5)

Why: the contrast is the atom: one of each, the hot-no-bubbles near-miss, the why, the puddle-is-boiling trap, one four-way term pick

Grade 4 · G4T03 L01 — What a magnet pulls

Seven "Does the magnet pull it?" including Grade 3's own non-examples

  • A magnet comes close to a steel nail. Does the magnet pull the nail?
  • A magnet comes close to a ball of aluminum foil. Does the magnet pull the foil?
  • A magnet comes close to a plastic ruler. Does the magnet pull the ruler?
  • A magnet comes close to an empty steel can. Does the magnet pull the can?

Keep: items 2, 5 (steel, iron), 3, 7 (copper, brass: the new no cases), 9 (coin inference), 10 (nickel and cobalt), 11 (misconception) (12 → 7)

Why: The new learning is the metals a magnet does not pull. The plastic ruler is Grade 3's non-example and the third steel case adds nothing.

Grade 4 · G4T13 L03 — Find the sample that matches two properties

Kept at eight: a two-step routine needs its run

  • Which sample in the table fails the first property, sinking?
  • The eraser, the paperclip and the glass marble all sink. Which one of them does a magnet pull?
  • Emilia wants a sample from the toy box that floats and that a magnet pulls. Which sample matches both properties?
  • She tests the water first, and she finds a sinker… Has she found the sample yet?

Keep: items 2–5, 7–10; only the recall of "magnetic" and the second sinks-and-magnet tray go (10 → 8)

Why: Cross out on the first property, test the second on what is left: the scaffold pair, two different property pairs, the none-match tray and the three order-of-steps items each check a different step. The lesson is the topic capstone and James's ceiling of ten is not reached.

Grade 4 · G4T24 L03 — Most of the water in the air comes from the ocean

One fact asked five ways

  • Of every 10 cups of water that go into the air, about how many come from the ocean?
  • Which place sends the most water into the air?
  • Did most of the water vapor in the air evaporate from the ocean?
  • A rain cloud hangs over a city. Did all of the cloud's water come from the city's river?
  • A rain cloud hangs over a town. Must all of the cloud's water have come from the ground right under the cloud?

Keep: items 3, 4, 6, 9 (9 of 10) (9 → 4)

Why: Items 3, 5 and 7 are the same datum in three wordings; items 6 and 8 are the same belief on two towns. Four items (the datum, an apply, the belief, the why) do the whole job.

Grade 4 · G4T23 L01 — Water falls from clouds: rain, snow, sleet and hail

Six yes/no sorts on one word, two of them obvious

  • Snow covers a street in Chicago by morning. Is the snow precipitation?
  • Water sprays from a garden sprinkler onto the grass. Is the spray precipitation?
  • Rain soaks a cornfield in Iowa. Is the rain precipitation?
  • Sleet bounces on a parking lot in Ohio. Is the sleet precipitation?
  • Drops of dew sit on a car in the early morning. The sky was clear all night. Is the dew precipitation?

Keep: items 1, 6, 7, 8, 9, 10 (6 of 10) (10 → 6)

Why: A child who has heard the word once sorts rain and a sprinkler without the lesson; snow (yes) and dew (the clear-sky near miss) are the two instances fluency needs. Fog and sleet add nothing.

Grade 4 · G4T23 L05 — Predict the drop's next step

The same recall and the same belief tested across lessons

  • Landon says a drop that reaches the sea has finished its journey for good. Is Landon right? (L05 item 9)
  • Laura says the water cycle ends when the rain reaches the sea. Is Laura right? (L03 item 6)
  • Water vapor cools and turns back into drops of water. What is this step of the water cycle called? (T24 L05 item 1; also T23 L03 item 2)

Keep: the first appearance each time (T23 L03 items 2 and 6) (10 → 6)

Why: Across Topics 23 and 24 the condensation term is recalled three times and the journey-ends-at-the-sea belief twice; later quizzes open with a recall the previous lesson already banked. Nine of this slice's cuts are of this kind.

Grade 4 · G4T35 L05 — Sort living things by how they get their food

Nine sorts on one option set: eleven items for a three-way sort

  • A bat eats moths at night. Which role is the bat?
  • A goat eats bushes on a hill. Which role is the goat?
  • A wild turkey eats seeds and bugs. Which role is the turkey?
  • A fern in a shady wood makes its own food, using sunlight. Which role is the fern?

Keep: items 1, 2, 3, 8, 10 (the term, one card per class, the eagle transfer) (11 → 5)

Why: Every item after the three cards asks the same decision on the same producer / consumer / decomposer set with only the animal changed. Four consumers and three producers teach nothing the first of each did not. Five items keep the term, one of each class and the eagle (nothing eats it, still a consumer).

Grade 4 · G4T29 L03 — Sort the seven resources: renewable or nonrenewable?

A two-way sort of seven resources asked seven times, then a transfer

  • Here is a card. Which group does its energy resource go in?
  • Here is another card. Which group does its energy resource go in?
  • A furnace in Minnesota burns natural gas. Which group does natural gas go in?
  • A power plant in North Carolina burns coal to make electricity. Which group does coal go in?

Keep: items 1, 2, 5, 8, 9 (one card per class, one text nonrenewable, the plants boundary, the four-option transfer) (9 → 5)

Why: Items 1-4 are four cards on renewable / nonrenewable and items 5-7 are three text cases all keyed nonrenewable. The sort is a one-step decision the lesson taught on all seven; five items are enough, and item 8 (plants take years but regrow) is the only one that needs the lesson's criterion.

Grade 4 · G4T37 L01 — How pollen moves from flower to flower: pollination

Nine yes/no items on 'Is this pollination?' in a thirteen-item quiz

  • The wind blows pollen from one oak tree's flowers onto another oak tree's flowers. Is this pollination?
  • A butterfly drinks from a lily, gets pollen on its legs, and lands in a second lily. Is this pollination?
  • At night, a moth crawls from one honeysuckle flower into the next, with pollen on its back. Is this pollination?
  • Rain washes pollen off a flower and onto the soil under it. Is this pollination?
  • A bee dusted with pollen from a squash flower goes straight back to its hive. Has the bee pollinated a second squash flower?

Keep: items 2, 3, 4, 8, 9, 10, 13 (where pollen comes from, a wind yes, an animal yes, the bee-goes-home no, both traps, the term) (13 → 7)

Why: Three yes cases and three no cases on one frame, then a trap asked twice (items 9 and 11, one keyed no and one keyed yes). One yes per carrier kind and the sharpest no (pollen carried, but to no second flower) cover the decision; the rest is the same instance again.

Grade 4 · G4T36 L04 — Traits that came from both

Eight 'where did it come from' items on one three-option set, four of them keyed 'both'

  • A puppy's parents are both big dogs, and the puppy gets plenty of good food while it grows. It grows into a big dog. Where did its size come from?
  • A lamb's parents are both small sheep, and the lamb drank very little milk while it grew. It grew into a small sheep. Where did its small size come from?
  • Here is a trait card for a horse's size. Where did the horse's size come from?
  • A boy can juggle three balls after a summer of practice. Where did his juggling come from?

Keep: items 1, 2, 3, 4, 9, 10 (one per class, a plant 'both', the trap, the written transfer) (10 → 6)

Why: The new idea is the third class ('both'); items 1, 4, 5 and 8 all key it on size or height with the animal changed, and items 6 and 7 re-ask the two classes Topics 36 L01-L03 already sorted. One of each plus the plant case is the fluency a one-step sort needs.

Grade 4 · G4T31 L02 — A year is one trip around the Sun

A one-fact lesson (one trip around the Sun is a year) with ten items, four of them the same term

  • Earth travels around the Sun along a curved path that comes back round. What is that path called?
  • Earth has traveled once around the Sun. What is that amount of time called?
  • Earth has made one whole trip around the Sun. Is that amount of time one year?
  • Earth has traveled once around the Sun. Type the name for that amount of time.
  • Type the name of the path Earth travels along as it goes around the Sun.

Keep: items 2, 3, 5, 6, 9, 10 (the number, the figure, the age transfer, the spin-vs-trip trap, the two typed terms) (10 → 6)

Why: 'Year' is asked three times (recognised, yes/no, typed) and 'orbit' twice; both words a Grade 4 child already has. The typed items alone do the recall job; the camping-trip item repeats the 9-years-old transfer.

Grade 5 · G5T03 L03 — How to plan the whole fair test

A plan lesson carrying four fair-test yes/no items when the next lesson (L03b) is a ten-item quiz of exactly that sort

  • A class tests whether a heavier sled slides farther down a hill. Both sleds start from the same line on the same hill, and nobody pushes them. Is this a fair test?
  • A class tests whether a heavier lunchbox needs a harder push to start sliding, and pushes the heavier lunchbox on a rougher floor. Is this a fair test?

Keep: items 1, 2, 3, 8, 9, 11 (11 → 6)

Why: The change / keep-same / measure scaffold is the routine; the sort has its own lesson. L03b itself goes from ten to six.

Grade 5 · G5T16 L05 — Name the four spheres

Eleven items on one four-option set: name the sphere, object changed each time

  • A big round rock lies on a hillside in Wyoming. Which sphere does the big rock belong to?
  • A tall cactus grows in the desert in Arizona. Which sphere does the cactus belong to?
  • Sand stretches for miles across a desert in Utah. Which sphere does the sand belong to?
  • A gray squirrel runs along a branch in a forest in Oregon. Which sphere does the squirrel belong to?

Keep: items 1, 2, 3, 4 (one per sphere), 5 (iceberg) and 10 (pond mud) (11 → 6)

Why: After one case per sphere and the two hard-to-spot cases (frozen water, wet mud), the other five are the same decision on a new noun. All five are clean four-option MCQs the PP100 bank can hold.

Grade 5 · G5T15 L01 — Describe a climate zone: its usual temperature and precipitation

The same three-zone sort asked forwards, backwards and as yes/no: ten items for one decision

  • Costa Rica is hot all year, and heavy rain falls most months. Which climate zone is Costa Rica in?
  • Which sentence describes the climate of a temperate zone? / It has warm summers, cold winters and rain most months.
  • Germany has warm summers and cold winters, with rain in most months. Is Germany in a temperate zone?
  • Indonesia is hot all year, with heavy rain most months. Is Indonesia in a polar zone?

Keep: items 1, 2, 3, 4, 9, 10 (10 → 6)

Why: Items 5-6 use items 2-4's stems as their options; items 7-8 run the same sort as yes/no. One item per zone, the descriptors item, the table transfer and the term do the job.

Grade 5 · G5T13 L05 — Rising, falling or staying level: which way the data is going

Seven graphs on rising / falling / staying level, two per class, plus a typed answer with no graph

  • Here is the thickness of the ice on a pond in Michigan this week. Which way is the data going?
  • Here is the height of a candle on a dinner table in Georgia, measured each hour. Which way is the data going?
  • A sunflower in Kansas was 20 centimeters tall on Monday and grew taller every day … Type the one word that says which way the data is going.

Keep: items 1, 2, 4 (one per class), 6 and 9 (a rise with a dip, a level with ups and downs), 8 (falling means shallower) (10 → 6)

Why: The second falling and second level graphs change only the instance; the typed item has no graph and 'grew taller every day' answers it without the lesson.

Grade 5 · G5T21 L03 — The same light looks dimmer the farther away it is

Seven fluency items on a fact a child already holds: a light looks dimmer farther away

  • A boat with one lamp sails away from the shore at night. How does its lamp look … as the boat gets farther away?
  • A car drives toward a boy at night with its headlights on. How do the headlights look as the car gets nearer?
  • Two of the same candles burn in a dark hall … The candle on the left looks dim. Which candle is farther from you?

Keep: items 1, 4, 7, 8 (8 → 4)

Why: One dimmer, one nearer, the boundary (two different lights, so brightness tells you nothing) and the why. The lesson exists to set up L04; four items hold it.

Grade 5 · G5T20 L05 — Why shadows change through the day

A capstone whose quiz re-asks the previous topic's shadow facts

  • Late in the afternoon in Texas, the Sun is low in the west. Which way does a tree's shadow point?
  • A boy's own shadow … is long at eight in the morning. What will his shadow be like at midday?
  • A post's shadow in Oregon points west at nine in the morning. Does the post's shadow point west at five in the afternoon too?

Keep: items 2, 3, 4, 5, 8, 10 (10 → 6)

Why: Four of ten items are Topic 19 L01 and L02 items in new towns. The chain this lesson adds (Earth turns → the Sun's place changes → the shadow changes) lives in the two whys, the ordering and the Sun-climbing link; those stay.

Grade 5 · G5T23 L02 — Biotic or abiotic: sorting the parts of an ecosystem

Seven two-option sorts on one frame; three cases carry the whole skill

  • On a forest floor, a mushroom grows on a fallen log. Is the mushroom biotic or abiotic?
  • Rain water fills a dip in the forest floor. Is the rain water biotic or abiotic?
  • Sunlight comes through the trees… biotic or abiotic?
  • The wind blows through the forest… biotic or abiotic?
  • A feather from a blue jay lies on the forest floor… biotic or abiotic?
  • A pine cone has fallen… biotic or abiotic?

Keep: items 1, 2, 3, 8, 9, 10 (10 → 6)

Why: The frame is 'alive, or once alive?'. One alive, one once-alive (the dead branch is the boundary), one never-alive, then the count item and the two terms. Four more sorts add instances, not skill.

Grade 5 · G5T32 L01 — What the brain does: it takes in messages and decides

Nine items keyed 'brain' in a row

  • A squirrel hears a dog bark and runs up a tree. Which part of the squirrel took in the message from its ears?
  • A girl sees a ball flying toward her face and ducks. Which part of her decided to duck?
  • A girl works out seven times eight in her head. Which part of her is doing the thinking?
  • A boy's brain decides to kick a soccer ball. Does his brain send a message to his leg?

Keep: items 3, 4, 5, 6, 10, 11 (11 → 6)

Why: Message in, message out, the tongue-did-not-decide trap, one remembering, the order item and the typed term cover the atom. The other five ask 'brain' again with the scene changed.

Grade 5 · G5T28 L04 — Surroundings change how a trait develops

'Which grows bigger?' five times before the idea is tested

  • One gets plenty of water and one gets very little. Which carrot grows bigger?
  • One puppy gets plenty of good food, and the other gets very little food. Which puppy grows into the smaller dog?
  • Here is a table of two pepper plants… Which plant grew in the poor soil?
  • One lives in a stream full of insects… After a year, which trout is most likely bigger?
  • One tree grows in a sunny, rich orchard and one on a windy, rocky hilltop. After ten years, which tree is most likely shorter?

Keep: items 1, 4, 5, 6, 8, 9, 10 (10 → 7)

Why: The lesson's point is in items 5, 6, 9 and 10 (the surroundings change what grew, not the instructions). Two which-grows items keep the fluency; three more are the same two-option pick.

Grade 5 · G5T22 L02 — Inner planet or outer planet?

Six identical inner/outer sorts, then two term items for the same pair

  • Venus is the second planet from the Sun. Is Venus an inner planet or an outer planet?
  • A planet is small, and made of rock. Is the planet an inner planet or an outer planet?
  • Saturn is the sixth planet from the Sun. Is Saturn an inner planet or an outer planet?
  • Jupiter is the fifth planet from the Sun, big and made mostly of gas. Is Jupiter an inner planet or an outer planet?
  • Mercury, Venus, Earth and Mars are the four planets nearest the Sun. What are these four called?
  • Jupiter, Saturn, Uranus and Neptune are the four planets farthest from the Sun. What are these four called?

Keep: items 1, 4, 7, 8, 9, 10 (11 → 6)

Why: One inner by position, one outer by made-of, the Saturn-surface trap and its why, the lander transfer, one term item. Every sort item already prints both terms as its options.

Grade 5 · G5T34 L02 — The bladder: a stretchy bag that stores urine

Three yes-or-no bladder states a child knows from life

  • A boy has just been to the toilet. What is his bladder like now?
  • A girl on a long bus ride has not been to the toilet for three hours… What is her bladder like now?
  • A boy at a movie feels that he needs the toilet. Which sentence is true about his bladder?

Keep: items 1, 2, 9 (9 → 3)

Why: Empty after the toilet, full after three hours — no lesson needed. Where the urine goes next, the job, and the typed term are the honest items.

Every lesson, one line each
