Part A: In order Divide. Think of the matching multiplication fact.

2 ÷ 2 = 1
4 ÷ 2 = 2
6 ÷ 2 = 3
8 ÷ 2 = 4
10 ÷ 2 = 5
12 ÷ 2 = 6
14 ÷ 2 = 7
16 ÷ 2 = 8
18 ÷ 2 = 9
20 ÷ 2 = 10
22 ÷ 2 = 11
24 ÷ 2 = 12

Part B: Mixed up Divide.

0 ÷ 2 = 0
12 ÷ 2 = 6
10 ÷ 2 = 5
22 ÷ 2 = 11
2 ÷ 2 = 1
20 ÷ 2 = 10
24 ÷ 2 = 12
18 ÷ 2 = 9
14 ÷ 2 = 7
8 ÷ 2 = 4
16 ÷ 2 = 8
6 ÷ 2 = 3

Part C: Missing number Write the number that makes each fact true.

18 ÷ 2 = 9
6 ÷ 2 = 3
8 ÷ 2 = 4
24 ÷ 2 = 12
10 ÷ 2 = 5
14 ÷ 2 = 7

Tips for teachers and parents

Say "divide by 2 means split into two equal groups." 14 ÷ 2 is 7, because two groups of 7 make 14.
Link each fact to doubling. If double 8 is 16, then half of 16 is 8.
Only even numbers divide by 2 with nothing left over. Every dividend on this sheet is even, which is a good pattern to point out.
For Part C, turn ___ ÷ 2 = 9 back into multiplication: 9 × 2 = 18.

Common mistakes

Doubling instead of halving, so 12 ÷ 2 becomes 24. Ask the student to read the sign aloud before writing.
Halving the tens and ones separately and making an error, such as 18 ÷ 2 = 14. Check with doubling: 14 + 14 is 28, not 18.

What to practice next

Move on to dividing by 5 or 10, then by 4, which is halving twice.

Frequently asked questions

What is the trick for dividing by 2?

Find half of the number. 16 ÷ 2 is half of 16, which is 8.

Why does this worksheet start in order?

Part A follows the 2 times table backwards so students see that each division fact comes from a multiplication fact they know.
