Groups of ten objects that can be counted in tens.

These are the multiples of ten which mark the tens boundary where the pattern of counting changes.

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

Count efficiently in groups of ten

Maths

In this unit pupils will count efficiently in groups of 2 5 10. They will recognise and explain the value of 1p 2p 5p 10p coins and how a single coin can be worth several pennies. In the future unit pupils will learn to represent equal groups as repeated addition and multiplication. They will use this knowledge to calculate the product and represent the 2x 5x10x tables in different ways.

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 count efficiently in groups of 2 and 5 and 10. They will recognise and explain the value of coins up to 10p and how a single coin can be worth several pennies.
