I use relays to review a lot of different subjects in my Algebra 1 classes. This one reviews order of operations and has answers with both positive and negative answers. It can be used at the end of Chapter 1 of the Prentice Hall CA Algebra 1 textbook, or anytime you want to review order of operations with your class.
Students have fun with Scavenger Hunts. They try hard to find the correct answer so their team can finish first!
It includes instructions of how to use the Scavenger Hunt, a worksheet that students can use to record their answers, and a homework worksheet that reviews order of operations.
