Students will practice simplifying numerical expressions using the order of operations with this Pyramid Sum Puzzle activity. They simplify each expression, write the solutions in the boxes, then cut out the boxes and paste them onto the template so that each solution is the sum of the two solutions directly above it. This includes both positive and negative integers. Addition, subtraction, multiplication, division, exponents, and grouping symbols are included. Problems include a range of difficulty.
