Place each puzzle piece so that each equation is connected to the matching sum or difference. Pairs should be made both vertically and horizontally.
This is a self checking puzzle since it can only be solved completely with correct pairs touching.
Two levels of complexity
Level 1: Adding and Subtracting without regrouping
Level 2: Adding and Subtracting with regrouping
Puzzles with frames are included so that students can solve the puzzles quickly for 10-15 minute station work.
Puzzles without frames give students a greater challenge and are more appropriate for quick finishers or longer station times.
