Evaluating Expressions Chain Activity | Order of Operations, PEMDAS

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.

What's included?

There's 8 pages included:

• 4 levels (4 pages) of evaluating expressions using order of operations.

  • Level 1: Positive integers only (9 problems)

  • Level 2: Positive and negative integers (9 problems)

  • Level 3: Positive Decimals (9 problems)

  • Level 4: Positive Decimals - longer (4 longer problems)

• answer key (4 pages)

Note: all four levels include exponents!
