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

Combine parts using the addition symbol

Maths

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.

Additive structures: addition

There are 3 large cars and 4 small cars. We can represent this as...

Jacob has some chocolate cakes and some cherry cakes (plain with a cherry on top). He represents them like this, 4 + 2. What does the 4 represent? 

Sofia represents this picture like this, 3 + 4. Match each numeral or symbol to the correct description of what it represents. 

Use numerals and the plus sign to represent the fingers held up in this picture. 

Which of the following does not represent the picture?

Which picture shows Sofia’s whole group of cakes. 

Look at the picture. How many pieces of fruit are in the whole group? 

Which part-part-whole model correctly represents this stem sentence?  5 is the whole, 1 is a part and 4 is a part. 

8 is the whole. 2 is a part and 6 is a part. 

6 is the whole. 2 is a part and 8 is a part. 

2 is the whole. 6 is a part and 8 is a part. 

Which one of these numbers cannot be a part of the whole in the picture shown?

Complete the stem sentence 7 is the whole: 2 is a part and {{   }} is part.
