This Year 3 Adding 'sub-', 'inter-' Application resource will give children a chance to write their own sentences using words with these two prefixes.

To get them started, they are provided with a list of root words which they have to match to the correct prefix to create new words. Then, they use the words they have created to write original sentences. Ensure children understand the meaning of their new words by providing dictionaries for this activity.

An answer sheet is provided for you to show your class an example of what a good response might look like.
