Amy has 50 pence. She buys a pencil for 30 pence. Tick the purse that shows how much money Amy has left.

We know that Amy has 50 pence and she spends 30 pence on a pencil. So we need to work out what 50 take away 30 is. We know that five take away three is two. So five tens, which is 50, take away three tens, which is 30, equals two tens, which is 20.

We need to find the purse that has 20 pence. The first purse has three five-pence coins. We could count in five three times to work out how much is in this purse: five, 10, 15. So the first purse doesn’t show the amount of change that Amy has.

Let’s look at the second purse. We have two 10p coins and one five p coin. 10 add 10 is 20. 20 add five is 25. So this purse has 25 pence. We’re looking for a purse which has 20 pence. So this is not the correct purse either.

This purse has a 20-pence coin and a five-pence coin. 20 and five equals 25 pence. So this is not the correct purse either.

The final purse has a 10-pence coin and two five-pence coins. We know that two fives make 10. 10 and 10 makes 20. We have to tick the purse that shows how much money Amy has left. So we have to tick the purse which has 20 pence. Amy had 50 pence. She spent 30 pence on a pencil. 50 take away 30 is 20. So we ticked the purse with 20 pence.
