128 CALCULATING •^ DIVISION

Division

Division is splitting a number into equal parts, or finding out how

many times one number fits into another number. It doesn’t

always work out exactly. Sometimes there’s a bit left over.

Division is sharing

When we divide something, like a number of

apples, we share it out equally. Each part of a

division calculation has its own special name.

12 ÷ 3 = 4

13 ÷ 3 = 4 r1

Dividend

What we divide

This means

“divide by”

Quotient

How much is in

each part

There are four

apples in

each basket

Divisor

How many parts

we divide it into

Three robots have come to pick the 12

ripe apples on this tree. How many

will each robot get? We need to divide!

If we divide, or share out, the 12

apples equally between the 3 robots,

each robot gets 4 apples. So, 12 ÷ 3 = 4

One more apple

What happens if there are 13

apples, rather than 12? The 3

robots still get 4 apples each,

but now there’s 1 left over. We call

the extra apple the remainder,

and we put an “r ” in front of it.

Division is sharing

something out

equally.
