Hints and Tips

Your child may be familiar with the concept of halving as he/she has probably had experience of sharing a cake, a drink or some sweets with another child.

This doesn't necessarily mean that he/she understands what it really means.

By doing practical sharing activities now, your child will be laying the groundwork for division.

Some of these activities can be incorporated into normal daily activities, such as preparing and eating meals, always remembering to use the correct mathematical vocabulary.

Essential Prior Knowledge

A whole (cake, pizza etc) can be cut into any number of pieces.

Know what the word equal means.

Have an understanding of fairness (this will probably come from real life experiences).

Activity

While preparing food, give your child the opportunity to cut or share food into halves.

Talk about how each half must be the same size, or equal, otherwise it would not be fair.

Encourage your child to identify the whole thing and each half.

Try this activity with different shaped food for example, pizza, bar cake, bars of chocolate or bread thins.

Show your child a pizza that has been cut into eight equal pieces and put on a plate in a non-circular arrangement. Ask your child to share it into two halves.

If your child is interested in football, or other team sports, make a selection of photos of famous players (an even number) and take turns to make a selection to make your own team. How many do you each have? Is it the same number?

Set up a teddy bears picnic with two toys and get your child to halve the food between the two toys. Make sure he/she halves the food equally between the two toys so each toy gets the same amount so it's fair.

Give your child some different shaped paper, squares, oblongs, circles, and ask him/her to fold them in half. Look at the two halves. Are they the same size?

Ask your child to choose two different coloured crayons and carefully colour each half using a different crayon.

Give your child two purses and some pennies (even number up to ten) and ask him/her to halve them between the two purses. Is there an equal number? How many pennies are in each purse? Is it fair?
