To split a whole up / to separate a whole into parts.

Combine parts using the addition symbol

Maths

Understand that parts can be represented in any order

Understand the use of the equals sign in equations

Understanding part-part-whole relationships

Add parts to find the value of the whole and write the equation

Find the missing part in an equation

Partition a whole into two parts and write as a subtraction equation

Using bar models to subtract

Understand the relationship between addition and subtraction

Understand addition as increasing a quantity

In this unit pupils will combine 2 or more parts to make a whole. They will learn addends are represented in any order and the = sign shows the whole and sum of the parts are equal. In the future unit pupils will find missing addends. They will partition a whole into 2 parts representing first, then, now stories with subtraction equations. They will learn + and - are inverse operations.

In prior learning, pupils will have learnt to count confidently and have developed a deep understanding of the numbers to 10, the relationships between them and the patterns within those numbers. In this unit pupils will combine two parts to make a whole, learn that addends are represented in any order and learn that the equals sign shows that the whole and the sum of the parts are equal.

In this unit pupils will combine 2 or more parts to make a whole. They will learn addends can be represented in any order and that the = sign shows the whole and sum of the parts are equal.

Additive structures: addition

To split a whole up into parts (pieces or sections of the whole).

= shows that what is on the left of the symbol is exactly the same amount or value as what is on the right of the symbol.

An equation says that two things are equal. It will have an equal sign like this =

An equation says that two things are equal. It will have an equal sign ( = ) and the expression on either side will have the same value.

This shows how the whole can be partitioned into parts and recombined. It demonstrates the equality between the parts and the whole.

Shows that one number or expression is equal to another.

Any numbers that can be added together to form a whole.

To separate or take away one number from another, or to decrease an amount.

The symbol in an equation which shows that a number has been partitioned, taken away or decreased.

The act of splitting an object or value down into smaller parts.

A piece or section of the whole that is known.

A piece or section of the whole that is not known.

To find the total, or sum, by combining two or more numbers (addends).

Coming before all others in time or order; earliest.

To make something larger/greater in size or quantity.
