Practice adding integers. Add (or combine) the two integers next to each other and place the sum in the box above those numbers. Continue working your way to the top of the pyramid until you have a single sum.

An answer key is provided.

Use this as a center, homework, bell-ringer, review, extra credit, etc. Also use as teamwork, with each student completing just one row of the pyramid. (Fold the paper up to cover other numbers below--helps kids focus and only worry about their row.) If the top number is not correct, students work together to find the error (closest to the base)
