Part A: In order Divide. Think of the matching multiplication fact.
- 9 ÷ 9 = 1
- 18 ÷ 9 = 2
- 27 ÷ 9 = 3
- 36 ÷ 9 = 4
- 45 ÷ 9 = 5
- 54 ÷ 9 = 6
- 63 ÷ 9 = 7
- 72 ÷ 9 = 8
- 81 ÷ 9 = 9
- 90 ÷ 9 = 10
- 99 ÷ 9 = 11
- 108 ÷ 9 = 12
Part B: Mixed up Divide.
- 27 ÷ 9 = 3
- 108 ÷ 9 = 12
- 36 ÷ 9 = 4
- 90 ÷ 9 = 10
- 0 ÷ 9 = 0
- 9 ÷ 9 = 1
- 72 ÷ 9 = 8
- 18 ÷ 9 = 2
- 81 ÷ 9 = 9
- 63 ÷ 9 = 7
- 54 ÷ 9 = 6
- 45 ÷ 9 = 5
Part C: Missing number Write the number that makes each fact true.
- 63 ÷ 9 = 7
- 72 ÷ 9 = 8
- 99 ÷ 9 = 11
- 36 ÷ 9 = 4
- 27 ÷ 9 = 3
- 45 ÷ 9 = 5
Tips for teachers and parents
- For dividends from 9 to 90, the answer is one more than the tens digit. 54 ÷ 9: the tens digit is 5, so the answer is 6.
- Check the dividend first: its digits must add to 9. If they do not, the number is not in the 9 times table up to 9 × 10.
- For 99 ÷ 9 and 108 ÷ 9, use the 9 times table directly: 9 × 11 = 99 and 9 × 12 = 108.
- Connect to the finger trick from the 9 times table for students who learned it.
Common mistakes
- Using the tens digit itself as the answer, so 63 ÷ 9 becomes 6. The answer is one more: 7.
- Using the pattern on 99 and 108, where it does not work. Point out that it only holds up to 90 ÷ 9.

Frequently asked questions
What is the trick for dividing by 9?
For numbers from 9 to 90 in the 9 times table, add one to the tens digit. 72 ÷ 9: the tens digit is 7, so the answer is 8.
Why does the tens-digit trick work?
In the 9 times table up to 9 × 10, the tens digit of each answer is one less than the number multiplied by 9.
