This Year 3 Adding Sub and Inter Mixed Activity resource provides a range of question types to challenge your pupils as they learn to use the prefixes 'sub-' and 'inter-'. Using this worksheet, children will sort root words according to which prefixes they can be used with, match words with meanings, fill gaps in sentences and explain how prefixes change the meaning of root words in context. Question types range across fluency, application and reasoning styles.

This worksheet is suitable for independent work, small groups or paired work. We've also included an answer page to make marking quicker and easier.
