Fact Triangles are similar in some ways to flashcards although they are a better way of showing and practicing fact families. Fact Families are sets of three numbers that can be divided or multiplied together and they help develop the understanding of the relationship between multiplication and division. Below are two examples:
|Number Family||Fact Family|
|2 , 3 , 6||2 x 3 = 6 , 3 x 2 = 6 , 6 ÷ 3 = 2 , 6 ÷ 2 = 3|
|4 , 7 , 28||4 x 7 = 28 , 7 x 4 = 28 , 28 ÷ 7 = 4 , 28 ÷ 4 = 7|
|Knowing one fact from a family helps recall the other three facts.|
Open and print this fact triangles sheet and then cut along the lines to produce the triangles. This should give you twenty-seven triangles.
To practice multiplication, cover the largest number (the product) with your thumb and ask your child to say both multiplication facts.
To practice division, show the largest number and cover-up one of the others.
e.g. for a triangle showing 20 , 4 & 5 , cover the 5 and ask your child to tell what 20 ÷ 4 =
Spend a few minutes each day on these activities and try to make them as much fun as possible.
