## Addition and subtraction within 10

• Year group: Year 1
• Term: Autumn
• Duration: 4 weeks
• Keystage: KS1
• Age Range: 5 to 6 yrs
• Unit can be taught out of sequence: N
• Week Range: 5 - 8

In this chapter, pupils build on their work on place value up to 10. In order to understand addition and subtraction, they should be able to compare and appreciate the size of numbers, as well as represent them using a variety of objects, such as counters and cubes.

Pupils start to read, write and interpret mathematical statements involving addition (+), subtraction (-) and the equals sign (=). They begin to understand what it means to add and subtract two numbers and use concrete objects and simple part-whole diagrams to represent this. They write related calculation statements using these representations.

Throughout this chapter, pupils explore how numbers within 10 can be partitioned and, as such, are able to represent and use number bonds of any number up to 10. They also add and subtract one-digit numbers (including 0) within 10.

Using concrete objects and pictorial representations, pupils solve simple one-step and missing number problems. They also start to understand the different uses of the subtraction symbol, such as to “take away” and “find the difference”.

## Resources for this topic

### White Rose Maths

#### Complements to Ten

These resources are great to follow on from work with a Ten Frame. They look at fact families within 10

#### Part whole models with 10

Basic part whole models for adding and subtracting numbers within 10

### Mathematics Mastery

#### Addition and subtraction within 10

Mathematical discussion is a key element of the Mathematics Mastery programme.

Talk Tasks are a brilliant way of enabling pupils to develop their mathematical language, thinking, understanding and confidence.

This activity explores the concept of Addition and subtraction within 10.

• Talk tasks are best completed in mixed attainment pairs, with pupils taking turns to listen and construct arguments
• Emphasis is on discussion rather than the solution, encouraging pupils to use key language and talk in full sentences
• Ask pupils to prove their answers in a variety of ways, using the CPA approach to support mathematical understanding and number sense

#### Find the difference numbers to 10

A powerpoint to introduce children to finding the difference between two numbers (to 10) through subtraction. Powerpoint includes visual representation to support children.

#### Adding one digit numbers with part whole models

Using part whole models to add one digit number, increasing difficulty with added reasoning and problem solving throughout.

#### Maths Y1 Summer Teaching Sequence 3

Adding and Subtracting, paritioning eight, nine and ten (three days).

Children revise recording the related subtraction facts for pairs to 10 and 8. They use the idea of equality and the image of the number balance to help them to write number sentences such as 7 + 3 = 6 + 4. Nine is partitioned into pairs of numbers using the familiar image of the coat hanger and pegs, and children write the related addition and subtraction facts. Children act out simple number stories, use number facts to find the answer, and then record the associated addition or subtraction. They create their own simple number stories using a writing frame.
