To say the number words in order, the last number tells how many there are in the whole set.

Instantly recognising the number of objects in a small group, without counting.

Explain that numbers can represent how many objects there are in a set

Maths

In this unit pupils will revisit how numbers are represented cardinally and ordinally. They will partition 1 - 5 in different ways and find a missing part. In the future unit pupils will represent numbers 6 - 10 by partitioning in different ways. They will learn what odd and even numbers are and how they can be partitioned. They will identify a missing part when a whole is partitioned into 2 parts

In prior learning, pupils will have explored the composition of numbers to 10 and be able to subitise up to 5. In this unit pupils will partition 1 to 5 in different ways and find a missing part.

Composition of numbers 0 to 5

We count one object at a time to find the total amount.

Lucas thinks there are 4 counters here. Is he right?  

Aisha thinks there are 5 counters here. Is she right?

What is the next number in the count? 1, 2, 3 ….

What is the next number in the count? 1, 2, 3, 4 …. 

Lucas thinks there are 3 counters here. What mistake has he made?      

Aisha thinks there are 5 cubes here. Is she right? 

This lesson will soon be taken down.
