Free printable math flash cards can is . We'll give you several ideas for turning these free math flashcards into a fun game. Or you can use them in the traditional way.

Have you used triangular flash cards yet? They can help kids learn a family of math facts. On the 3 corners of a triangle, you have a number in a certain fact family. For example, you may have 4 in one corner, 6 in another, and 10 in the other corner.

Your The child is to say the fact family number sentences that go with those numbers. So they will say 4+6=10, 6+4=5, 10-4=6, 10-6=4. These reinforce fact families and help them see the relationships between addition and subtraction problems.

The addition facts can be seen as "families" of numbers: two "terms" and a "sum." In the case illustrated here, the two terms are 8 and 3, and the sum is 11. If the parent presents the card to a child with the top number covered, it is an addition problem. The goal is to add 8 and 3 to get 11. However if one or the other of the bottom numbers is covered, it becomes a subtraction problem: 11 – 8 = 3 or 11 – 3 = 8.

I make mine on poster boards cut into triangles with rounded corners about the size of my hand. Not only are free math flashcards are good for skill building but they are great for test prep as well.
