Fact Family Triangles: Multiplication and Division

What is the primary purpose of a fact triangle?

• To represent fact families

• To solve complex equations

• To visualize geometric shapes

• To calculate prime numbers

Does this show the commutative property?:

8x2 = 8x2

• Yes

• No

Given a fact family with numbers 2, 9, and 18, which two multiplication facts can be derived?

• 9 x 2 = 18 and 18 x 2 = 9

• 9 x 2 = 18 and 2 x 9 = 18

• 18 x 9 = 2 and 18 x 2 = 9

• 2 x 18 = 9 and 9 x 18 = 2

From the fact family 2, 9, and 18, what are the two division facts that can be derived?

• 9 / 2 = 18 and 2 / 9 = 18

• 18 / 9 = 2 and 18 / 2 = 9

• 18 / 2 = 9 and 9 / 18 = 2

• 2 / 18 = 9 and 9 / 18 = 2

How can a fact triangle be used to quiz oneself on multiplication facts?

• By adding all three numbers together

• By covering one corner and multiplying the other two numbers

• By subtracting one number from another

• By dividing the top number by the bottom two numbers

If you cover the number 2 in a fact triangle (with 18 at the top, 9 and 2 at the bottom), what operation would you perform with the remaining numbers to find the hidden number?

• 18 + 9

• 18 - 9

• 18 / 9

• 9 x 18
