This is a winter-themed tarsia puzzle that I made to help students practice their skills adding and subtracting integers. When correctly put together, the pieces make a snowflake.
Each problem contains 3 numbers, between -20 and 20, that are being added or subtracted. Examples include "-1-3+7" and "20+(-5)-(-4)."
