This is a partner game for students to play to practice finding missing parts, wholes, and percentages. Each set of two students needs dice, the "let it roll" sheet, and scratch paper. To play they roll two dice, combine the values in some way (add, subtract, etc), and then solve the problem that matches that number. The students solve separately, but then compare answers. They must agree before moving on and rolling the dice again. This results in some great conversations about percentages and different problem solving strategies that the students are using to solve. There is a "regular" sheet and a "challenge" sheet, which has slightly more complex problems. You can assign students to a specifc version of the game, or can let them choose based on their self-assessment.
