To subtract numbers within 20 using mental strategies
SUBTRACT SNAP CRACK is a Grade 2 mental-subtraction game for differences within 20. Two cards are turned face up, students subtract the smaller value from the larger, and the first player to call the correct difference keeps the cards. Tied calls leave the cards in the center so the next round can be worth more.
Use it for partner or small-group practice when students are building subtraction fluency and efficient mental strategies. Because the cards change quickly, students get many opportunities to compare values before subtracting.
