The pears at a grocery store are arranged in a display. The display has 4 rows, with 8 pears in each row. Which equation shows how to find the total number of pears?

• 4 + 8 = 12; This answer uses addition instead of multiplication.

• 4 x 8 = 32; Multiply 4 x 8 to find the total number of oranges.

• 4 + 8 = 8 + 4; This answer rearranges the addition of the factors.

• 4 + 4 + 4 + 4 = 16; This answer uses repeated addition of 4 instead of 8.

Choose the THREE number sentences where 6 will make the number sentence true.

• This is the result of not understanding that in this number sentence the unknown number is 7 because 7 x 4 = 28.

• This is the result of not understanding that in this number sentence the unknown number is 5 because 7 x 5 = 35.

• This is the result of knowing that in this number sentence the unknown number is 6 because 3 x 2 = 6.

• This is the result of knowing that the unknown number is 6 because 4 x 6 = 24.

• This is the result of knowing that the unknown number is 6 because 6 x 10 = 60.
