To subtract numbers within 30 using mental strategies
SUBTRACT SNAP SNAP CRACK is a Grade 2 mental-subtraction game that uses three card values instead of two. Students subtract the smallest value from the largest, then combine that difference with the middle value according to the game’s rule and race to call the final answer. The extra step makes students hold an intermediate result and adjust it mentally.
Use it for small-group practice when students are ready for more demanding subtraction within 30. Asking students to state the first difference before the final step can help you hear where an error occurs.
