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.
