Another card set is used for both multiplication and division. One point of each

card shows a product (the answer to a multiplication problem). The other two points show factors—the numbers you multiply together to get the product.

Practice multiplication facts by

covering the product.

4 × 6 = 24 6 × 4 = 24

Practice division facts by covering

one of the factors. Cover the other

factor, too, so you can memorize

both division facts on the card.

24 ÷ 6 = 4 24 ÷ 4 = 6

In math, paying attention to patterns pays off. Triangle flash cards help you learn

addends and sums, and factors and products, as groups of numbers that go

together. Thinking about math facts in these groups will take you farther than

just memorizing math answers. When you make sense of numbers this way,

it can make learning math so much easier!
