Monster Memory Subtraction Edition may be played individually or in partnerships. The object of the activity is to find the most pairs of matching cards! I recommend using this activity as a center.
This download contains 4 different subtraction-themed games: Basic Fact Practice, Subtraction without Regrouping, Subtraction with Regrouping, and Subtraction Across Zeros. These 4 choices allow you to differentiate easily among your class.
What a fun way to have your students develop concentration and memory skills while also practicing subtraction!
