This Year 3 Adding Sub and Inter Teaching PPT provides a step by step lesson that includes everything your class need to know about these two prefixes.

Check the meaning of 'prefix' by looking at one which they should know already - 'un'. Extend their learning to 'sub' and 'inter' and the root words that they match. Help them to understand the meaning of each prefix and how this changes the root words.

Following an explanation of the objective, this PowerPoint supplies a range of question types for you to discuss with your class, from fluency to reasoning and application. Each question is followed by an example answer.

Use this PowerPoint to ensure children develop confidence before completing the follow-up resources that we have for this step.
