Dividing means sharing so that every part is the same — that is fair.
Deal out one to each, like cards, until everything is gone. Each person ends with an equal share.
Half means sharing into 2 equal parts. Half of 8 is 4.

Worked example. Share 12 toffees equally among 3 friends.

Deal them out: each friend gets 4, because 3 × 4 = 12.

Another way to divide is to make groups of a fixed size and count how many groups.
The sign ÷ means “divide”. 10 ÷ 2 = 5 means 10 shared in 2s makes 5 groups.
You can keep subtracting the group size: 10 − 2 − 2 − 2 − 2 − 2 = 0, that is 5 jumps.

Worked example. 18 laddoos go into boxes of 6. How many boxes?

18 ÷ 6 = 3 boxes, because 3 groups of 6 make 18.

Sometimes a number does not split evenly, and a little is left over.
Share 11 biscuits on 2 plates: 5 on each (that is 10), and 1 left over.
Multiplying and dividing are partners: if 4 × 6 = 24, then 24 ÷ 6 = 4 and 24 ÷ 4 = 6.

Worked example. Share 9 sweets between 2 children equally.

Each gets 4 (2 × 4 = 8) and 1 is left over, because 9 does not split into 2 equal whole parts.

Common mix-up: a fair share means each part is the same. Giving one child more is not dividing equally.

Where you’ll meet it

Sharing a packet of biscuits with friends so everyone gets the same number is dividing in action.

Making equal teams from the class means dividing the children so each team is the same size.

Putting the same number of fruits in each box tells you how many boxes you will need.
