Friday 27th March - Maths Challenge (Time)

Hello year 4!
Warm - Up: Multiplying by 10 and 100

Remember - The rule for multiplying by 10 is that the digits stay the same but move 1 place value column to the left. We usually fill in the place holder with a zero.

For example:

3 x 10 = 30

15 x 10 = 150

2.3 x 10 = 23 or 23.0

For multiplying by 100 the digits go 2 spaces to the left and we may need to fill in 2 place holders:

For example:

3 x 100 = 300

15 x 100 = 1500

2.3 x 100 = 230 or 230.0

Here are your questions:

5 x 10
14 x 10
35 x 10
63 x 10
90 x 10
4.6 x 10
53.2 x 10
9 x 100
14 x 100
453 x 100
65.9 x 100
