Fifty-five triangle cards, six to a sheet, one for every multiplication fact family to 10 × 10, from 1, 1 and 1 to 10, 10 and 100, in order of the product. The product sits at the top corner and the two factors at the bottom corners, with × and ÷ between them. One child covers a corner and the other names the hidden number: cover the product and they multiply, cover a factor and they divide. The cards have no backs, so print them one-sided, and cut along the dashed line around each one.
In pairs, one child covers a corner and the partner says the hidden number and the fact they used ("42 ÷ 6 = 7"). Hand out one table's triangles at a time, such as every card with a 6. Ask for all four facts of a family: 6 × 7, 7 × 6, 42 ÷ 6 and 42 ÷ 7.
Pick out the triangles for the table your child is learning and practice those first. Cover the product to practice multiplying and a factor to practice dividing.
