## Multiplying by 10, 100 and 1000

The worksheets above test the students’ ability to multiply by 10 and 100. This is quite simple, it just takes practice. These questions should be answered mentally and are easier for students who have fast time table recall.

Strategy: The strategy I teach my class is to ignore the zeros and multiply the numbers, and then add the zeros back to your answer. Simple!

Example 1: 40 x 80 – Ignore the 2 zeros. 4 x 8 = 32.

Add the zeros back on, answer is 3,200

Example 2: 60 x 300 – Ignore the 3 zeros. 6 x 3 = 18.

Add the zeros back on, answer is 18,000

Example 3: 700 x 500 – Ignore the 4 zeros. 7 x 5 = 35.

Add the zeros back on, answer is 350,000

Multiplying by 10, 100 and 1000 should be taught first and then should be practised during mental math. Add these questions into your daily warm up and your class will improve in no time!
