Everything you and your pupils need to know about Year 3 addition and subtraction – all in one place.

This Year 3 addition and subtraction knowledge organiser has been designed with the principles of cognitive load theory in mind to support pupils understand and learn important addition and subtraction concepts.

The relevant knowledge is intentionally structured and laid out so that pupils can see the key vocabulary, topic explanations and examples from the statutory requirements for Year 3 addition and subtraction all on one sheet.

You can use these knowledge organisers in a variety of ways to improve pupils' understanding of addition and subtraction.

Individual pupils can use the knowledge organisers as prompts during lessons, as revision or to self assess their skills.

Teachers can use them to ensure progression across year groups or display the knowledge organisers on working walls in the classroom.

Alternatively, you can send knowledge organisers home at the start of term or block of work to ensure consistent language and mathematical methods across home and school.

The pack includes a Year 3 addition and subtraction organiser and a KS1 addition and subtraction knowledge organiser for mixed Year 2 and 3 classes.

As a shared body of information these knowledge organisers provide a very useful tool for pupils, school staff and parents to understand everything the National Curriculum outlines for a specific year group at a glance.
