How to Measure: An Illustrated Manual

The Definitive Treatise, by PDS First Graders.

1. “There can’t be gaps when you measure. You have to push the measuring things together, like this.”



2. “And you can’t make the rods all zigzag. You have to put them together in a straight line, like this. Don’t get off track.”





3. “The first thing is you have to estimate how many rods will fit.”



4. “You should look at it carefully. Then you can use your fingers to help you estimate.”



5. “You start by putting the first rod down so its end is right at the edge of the thing you’re measuring.”



6. “Then put more of them along the side, like this.”



7. “Go until you get to the other end of what you’re measuring! Then count how many rods you used.”




And now you know how to measure!
