The school fete

Name:

Saturday was the school fete. Everyone in Lindsay’s class was very excited. They were looking forward to the games that would be played. The cake stall and the ice-cream stall were going to be the best places to be.

pl e

On the day of the fete Lindsay and her friend Joanne played many games and won a lot of prizes which they put into a large paper bag. At the end of the day they were very tired and very happy.

Sa m

They had a problem. The girls had forgotten who had won which prizes in their bag. They didn’t want to argue, so they decided to share the prizes evenly. That way each girl had the same number of prizes from the fete. Do you think this was the best way to solve the problem?

Sharing

Name:

Cathy and Simon were very good friends and always played together at lunchtime. They played basketball and football all of the time.

One day the children were happily playing a game of marbles when a bully came along and told them that he was going to take their marbles.

Sa m

The children quickly put all of the marbles in Cathy’s bag, which was the closest, and ran home to Simon’s house. They were happy that they had escaped from the bully and still had their marbles. But they now had a big problem, all of their marbles were in the one bag!

Name:

When we share things it can be done in two ways.

Sa m

The first way is where we share one object, like a cake, among a group of people. Each person gets one share of the cake. This share can also be called a fraction. Draw lines to show how you would share this cake among four people.

The second way is where we share a group of objects, like a bag of sweets, among a group of people. Each person gets one share of the sweets. This share is also called a fraction. Show how you would share these mints among three people.

A fraction is a part of something or a part of a group of things.
