SUBTRACTION FACT WAR

SUBTRACTION FACT WAR is a Grade 1 card game for subtracting from a shared fact-family number. Each player flips one card, subtracts that value from the number shown on the game board, and compares the differences. The smaller difference wins the cards, while ties trigger a War round with bonus cards and another subtraction.

Use it for partner work when students are building subtraction fluency within 20. Because every player subtracts from the same starting number, the game makes it easy to compare how a larger subtrahend produces a smaller difference.
