Addition Triangles turn math facts into a hands-on puzzle kids can see and touch. Each durable melamine triangle shows a sum at the top and two addends at the bottom corners, with a color-coded visual in the center that makes the relationship between numbers concrete. Kids cover one number at a time to practice addition, subtraction, or finding the missing number in a fact family. The cover-and-reveal format lets learners self-check as they go, building fluency with sums up to 18 without relying on worksheets.
