Modified by The Match Foundation, Inc.Do the Workshop section of SERP's Poster Problem "No Matter How You Slice It", including Handout #2. Students can work in pairs or in small groups.
Handout #2:
Make up and solve two of your own slicing problems. In problem A, you should not have any cheese left over, and in problem B, you one must have some cheese left over.
For each problem, you need to determine how much cheese you start off with: how long is your block of cheese? You also need to say how thick you want the slices of cheese to be—or you can decide how many slices you will need in total. Keep in mind that the thickness of each slice should be between $${\frac{1}{32}}$$ and $${\frac{1}{2}}$$ inches thick.
After you create your problems, make a poster showing each problem and its solution. Each solution should include an explanation, at least one calculation, and a diagram.

There are other ways to think about division of fractions. Try these two questions. They both use division, but why? And how do you know what to divide by what?
