Greater means a larger amount, so if a number is greater than another, it represents a larger amount.

Less means a smaller amount, so if a number is less than another, it represents a smaller amount.

Order and compare decade numbers on number tracks 

Maths

In this unit pupils will extend their counting to counting the decade numbers and making representations using a variety of different manipulatives. In the future unit pupils will extend their learning by counting to 100. They will explore the pattern in counting and focus on the end of the decade and the start of the new decade numbers.

In prior learning, pupils will have verbally counted beyond 20, recognising the pattern of the counting system. In this unit pupils will extend their counting o the decade numbers and represent them in different ways.
