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

A number that tells the position of something in relation to something else.

A number that shows how many of something there are.

Ordinal numbers that describe the position of something.

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

Partition means to split up a whole into parts.

A part-part-whole model is a pictorial representation that shows the whole and its parts.

Partition numbers one to five in different ways

Any way two or more parts can be put together.

Having an order to the way we work, identifying and using patterns.

A way of showing information (such as numbers and descriptions), arranged in rows and columns.

Partition the numbers one to five in a systematic way

A missing part means one of the parts that cannot be seen.

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

A missing part is one of the parts that cannot be seen.

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

The number after a given number is one more than it.

The number before a given number is one less than it.

A number that is before another comes earlier in our count.

A number that is after another comes later in our count.

Show one more and one less than a number using representations

A line with numbers placed in their correct position.

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

A bar model is a pictorial representation of a problem where bars are used to represent the known and unknown quantities.

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

Partition is to split a whole up into parts.

Combine means to put parts together to make a whole.

A bar model is a pictorial representation of a problem where bars are used to represent the whole and the parts.
