The video is being made. Until it arrives, here is what it will say (112 words, about 56 seconds):

It's a hot afternoon at the pool. Farah says it's really hot. Musa says it's super hot.

But how hot is it? On the wall, a thermometer holds the answer, as a number.

Now let's go to the kitchen. Farah wants to know how much apple she has. Not 'a bit', but a number.

And out in the yard, two teams measure the same puddle. They get two different numbers. Who's right?

That's what this topic is about: the tools that turn 'how hot', 'how much stuff' and 'how much liquid' into numbers, and what to do when two teams disagree.

Okay, so are you ready to put some numbers on it?
