• Partition

• division

• quotient

• array

To separate into equal groups to find the number of groups or to find the number in each group

• array

• division

• inverse operations

• repeated subtraction

operations such as multiplication and division which undo each other

• fact family

• divisor

• partition

• inverse operations

A way to subtract the same number over and over again until you reach 0.

• fact family

• array

• repeated subtraction

• divisor

The answer to a division problem

• array

• quotient

• fact family

• partition

A group of related facts using the same number...

5 x 3 = 15

3 x 5 =15

15 ÷ 3 = 5

15 ÷ 5 = 3

• array

• division

• fact family

• divisor

The number by which the dividend is being divided

• divisor

• quotient

• fact family

• repeated subtraction

An arrangement of items in rows and columns

• array

• partition

• division

• inverse operations

Eight counters into two equal groups.

• 8 ÷ 2 = 4

• 8 x 2 = 16

• 16 ÷ 2 = 8

• 2 ÷1 = 2

12 counters, 4 equal groups.

• 4 ÷ 2 = 2

• 12 ÷ 4 = 3

• 12 ÷ 2 = 6

• 4 ÷ 1 = 4
