This week in year 4 we have been multiplying by 10, 100 and 1000.

Today we explored how big we would be if we were giants!

We measured out body parts and multiplied ourselves, imagine that giants running round the school!

Here is how big we would be if we were giants.

Head 23

23 X 100 =2,300

23 x 1000 = 23,000

Leg 77

77 x 100 = 7,700

77 x 1000 = 77,000

Arm 42

42 x 100 = 4,200

42 x 1000 = 42,000

Hand 15

42 x 100 = 2,500

42 x 1000 = 25,000

Foot 23

23 x 100 = 2300

23 x 1000 = 23000

Waist 65

65 x 100 = 6500

65 x 1000 = 65000

Torso 33

33 x 100 = 3300

33 x 1000 = 33000

Mrs Verna: What is the rule for x100 and x1000?

When multiplying by 100 you move 2 spaces to the left.

When multiplying by 1000 you move 3 spaces to the left.
