Does the left have more soda? Does the right have more soda? Do they have exactly the same amount of soda?
- Teacher noteHave students write down a guess and share it with their neighbors. Then you should take a poll of the glass. Who thinks left? Who thinks right? Who thinks the same?
Act Two
- 1.
What information will you need here?
- Teacher noteNo question is too small or too picky or too precise. Just write it all down next to student names. If a student says, "We need to know how thick the glass is," give a lot of status to that kid for identifying variables with such precision.
You'll want to stage a fight over radius, circumference, and diameter. Which is easiest to measure? Why? How would you do it.
Then give the measurements you brought with you. - ImageMeasurements
- Teacher noteIn one version of this problem it was useful to cover up all the measurements but one and ask the students to estimate the other quantities.

Sequel

- 3.
"All you have to do is multiply the radius and height on both cylinders and compare them," someone told me. Is she right?
