Now, let us develop the table of 10.

Steps 10’s Total Table of 10

1 10 10 1 × 10 = 10

2 10 + 10 20 2 × 10 = 20
3 10 + 10 + 10 30 3 × 10 = 30

4 10 + 10 + 10 + 10 40 4 × 10 = 40

5 10 + 10 + 10 + 10 + 10 50 5 × 10 = 50

6 10 + 10 + 10 + 10 + 10 + 10 60 6 × 10 = 60

7 10 + 10 + 10 + 10 + 10 + 10 + 10 70 7 × 10 = 70
8 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 80 8 × 10 = 80

9 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 90 9 × 10 = 90

10 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 100 10 × 10 =100

Note: To multiply a number by 10, we just write the number and put 0 after it.

EXERCISE 2.1

A. Fill in the boxes.

1. 6 + 6 + 6 + 6 + 6 + 6 = × 6

2. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = × 7

3. 8 + 8 + 8 + 8 + 8 + 8 = × 8

4. 9 + 9 + 9 + 9 + 9 + 9 + 9 = × 9

5. 10 + 10 + 10 + 10 + 10 + 10 + 10 = × 10

B. Fill in the boxes.

1. 6 + 6 + 6 + 6 + 6 = 5 ×

2. 7 + 7 + 7 + 7 + 7 + 7 + 7 + 7 = 8 ×

3. 8 + 8 + 8 + 8 + 8 + 8 + 8 = 7 ×

4. 9 + 9 + 9 + 9 + 9 + 9 + 9 = 7 ×

5. 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 = 8 ×
