Product includes colorful labels to create an egg carton game and a reproducible student response sheet to record answers. Students shake the carton to see where the two pom-poms land (numbers 1-12), and then write an addition fact and the corresponding subtraction fact for those two numbers. After practicing facts, students write and solve a multi-step word problem involving both addition and subtraction. Can be used as an independent math station or as a partner game for students who are just learning addition and subtraction or for upper grade students who have not mastered basic facts. Teacher instructions for making the egg carton included.
