Multiplication Table of 9

Repeated addition by 9’s means the multiplication table of 9.

(i) When 7 heaps having nine footballs each.

By repeated addition we can show 9 + 9 + 9 + 9 + 9 + 9 + 9 = 63

Then, nine 7 times or 7 nines

7 × 9 = 63

Therefore, there are 63 footballs.

(ii) When 4 groups having nine crabs each.

By repeated addition we can show 9 + 9 + 9 + 9 = 36

Then, nine 4 times or 4 nines

4 × 9 = 36

Therefore, there are 36 crabs.

We will learn how to use the number line for counting the multiplication table of 9.

(i) Start at 0. Hop 9, two times. Stop at 18.

2 nines are 18         2 × 9 = 18

(ii) Start at 0. Hop 9, eight times.

Stop at ____. Thus, it will be 72

8 nines are 72        8 × 9 = 72

(iii) Start at 0. Hop 9, twelve times.

Stop at ____. Thus, it will be 108

12 nines are 108         12 × 9 = 108

How to read and write the table of 9?

The above chart will help us to read and write the 9 times table.

Now we will learn how to do forward counting and backward counting by 9’s.

Forward counting by 9’s: 0, 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225.

Backward counting by 9’s: ……, 225, 216, 207, 198, 189, 180, 171, 162, 153, 144, 135, 126, 117, 108, 99, 90, 81, 72, 63, 54, 45, 36, 27, 18, 9, 0
