Ordinal numbers show the position of an object in relation to another

Maths

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

Partition numbers one to five in different ways

Partition the numbers one to five in a systematic way

Find a missing part when one part and the whole is known

Solve problems finding a missing part when one part and the whole is known

Show one more and one less than a number using representations

Show one more and one less than a number using representations and describe this accurately

Use a bar model to represent a whole partitioned into two parts

Solve problems using a bar model to represent a whole partitioned into two parts

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.

In this unit pupils will revisit how numbers are represented cardinally and ordinally. They will partition 1 - 5 in different ways, find a missing part when one part and the whole are known and explore one more and one less with numbers to five.

Composition of numbers 0 to 5

The position of an object in a set in relation to something else.

Which one of these in an ordinal number?  

Match the ordinal number to the word that represents it.   

Who is first in the line to go through the door?

Who is fifth in the line to go through the door?

What mistake has Andeep made in his count?

Andeep thinks there are 5 cars in the line. Is he correct?

Laura thinks there are 5 cars in the line. Is she correct?
