This resource is a cooperative learning activity designed to be used during class.
There are four versions of the activity page, labeled A, B, C and D.
Students are put into groups of 4 and each group member is given a different version.
Students rotate each version around their group as they work on the problems.
The solution to each problem is a crucial component of solving the next.
If you have a group of 2 or 3, the activity will still work. Just handout 2 or 3 versions and the students can keep trading around or back and forth until all 4 problems are complete.
If you have lower level students, you may want to make modifications such as giving every student in a group the same version so they can help each other more and discuss the answers with each other as they work their way through the challenge.
*All answer keys are included.
