Subtraction Rummy

Subtraction Rummy is a Grade 2 card game where students build “books” of three or four cards that share the same difference. Players draw from the deck or discard pile, lay down matching sets, and can add cards to books that are already on the table. The Rummy structure makes students recognize equivalent subtraction results across different facts.

Use it in a small group when students are ready to move beyond isolated subtraction facts and notice relationships among several equations with the same answer. Ask students to read one book aloud as a set of subtraction sentences before play continues. Create a free Find a Math Game account to generate teacher-ready lesson support for Subtraction Rummy.
