## Why you'll love this

Looking for a fun way to practice using order of operations/PEMDAS to simplify expressions? You've found it.

Chain Reaction is a zero-prep activity where students work to find the solution to the current problem — which reveals the next problem on the chain. Students continue solving all the problems to reach the end of the chain. A small self check is built in per level — if their math is correct, the ending number should match their last solution.

This activity includes four difficulty levels so that you can differentiate students, or play back-to-back to practice. None of the questions overlap.
