How do the triangle cards help with addition and subtraction?

Each triangle card has three numbers in two colors: blue and red. To practice, cover one number. If the two remaining numbers are the same color (both blue), add them. If they are different colors (one blue, one red), subtract the blue number from the red number. This method builds automaticity for both addition and subtraction facts.

Multiple ways to learn subtraction

This set supports visual learners with color-coded cards, verbal learners with unique hints on each card, kinesthetic learners with counters and ten frames, and read/write learners who can write on the laminated surface. Learners can cover the answer to see only the hint, then check their work. The 30 counters help with real-world problem solving.

Built to last

Cards are made from thick art card paper with durable lamination that resists water and wear. They are fully writable and erasable with the included dry erase markers. The attractive storage box keeps everything organized.
