Cave Game Subtraction

Illustrative MathematicsVaries

The purpose of this task is for students to practice creating and memorizing subtraction equations, while focusing on missing addends. Once the students understand how to play the game, they can be given total numbers to work with that are applicable to their level of understanding. This is an excellent game to play with small groups of students, with whole numbers ranging from 5 up to 20. It can also be played several times throughout the school year, whole class, in groups, or in partners, using larger numbers as the class as a whole becomes more advanced.
