Not wasting time or effort. An efficient strategy is one we can carry out easily.

Calculate amounts up to 20 p

Maths

In this unit pupils will use knowledge of the value of coins and calculate the total value of the coins in a set of 2p 5p 10p coins. In the future unit pupils will consolidate their recognition and knowledge about the value of different denominations of coins. They will solve simple problems in a practical context involving addition and subtraction of money of the same unit.

In prior learning, pupils will have had opportunities to use manipulatives to organise counting including using everyday manipulatives, tens frames and through measures. In this unit pupils will use knowledge of the value of coins to calculate the total value of the coins in a set of 2p 5p and 10p coins.
