Multiplying by Tens at the Stadium

Multiply one-digit numbers by multiples of 10.

Think in tens

Use tens to help you multiply.

To find 4 × 30, think of 30 as 3 tens.
4 × 3 tens = 12 tens, and 12 tens = 120. So 4 × 30 = 120.

5 × 40 = 5 × tens = tens =

7 × 60 = 7 × 6 tens = tens =

3 × 90 = 3 × tens = tens =

Which shows a correct way to find 8 × 50?

A. 8 × 5 ones = 40 ones = 40
B. 8 + 50 = 58
C. 8 × 5 tens = 40 tens = 400
D. 8 × 5 tens = 13 tens = 130

Facts with tens

Find each product or missing number. Each missing number is a one-digit number or a multiple of 10.

Match each fact to its product.

4 × 30
6 × 50
9 × 80
2 × 70

A. 720
B. 140
C. 120
D. 300

6 × = 240

× 90 = 450

8 × = 480

Circle each fact that has a product of 360.

5 × 704 × 906 × 603 × 608 × 509 × 40
