FREEBIE! Fourth-grade Addition (add multi-digit whole numbers) has 81 addition problems in the format of a Tic-Tac-Toe game. Students work with a partner on the skill: adding multi-digit whole numbers. There is no need for teacher-grading or an answer key since each player must check the answer of their opponent (an incorrect response results in a loss of a turn).
