Explain what a whole is

Maths

Explain that items can be compared using length and height

Explain that items can be compared using weight and mass

Explain that items can be compared using capacity

Count a set of objects

Solve problems by comparing sets of objects

Use equality and inequality symbols to compare sets of objects

Use equality and inequality symbols to compare the relative size of two numbers

Explain that a whole can be split into parts

Explain that a whole can represent a group of objects

Identify a part of a whole group

Explain what a part-part-whole model is

Use a part-part-whole model to represent a whole partitioned into two parts

Use a part-part-whole model to represent partitioning into more than two parts

Solve problems using part-part-whole models with more than two parts

In this unit pupils will explain that items can be compared using length and height, mass and volume/capacity. They will compare sets of objects using equality/inequality symbols. In the future unit pupils will combine 2 or more parts to make a whole. They will learn that addends can be represented in any order and that the = sign is used to show the whole and sum of the parts are equal.

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 explain that items can be compared using length, mass and capacity and use the inequality symbols.

In this unit pupils will explain that items can be compared using length and height, mass and volume/capacity. They will compare sets of objects using equality/inequality symbols. Pupils will also explore part-part-whole relationships with representations.

Comparing quantities - part part whole relationships

Something that is complete, it is all there.

Something that has a part missing, it is not all there.

An opening in the floor that we need to fill.

A piece of a whole. The whole is not all there.

There are the same amount of apples and oranges.
