A Year 1 resource pack for teaching how to use the prefix ‘un’ to change the meaning of words. The interactive PowerPoint explains what a prefix is, shows how adding ‘un’ makes a word mean “not” or the opposite, and gives clear examples in context. The task sheet provides opportunities to practise by adding ‘un’ to words, identifying which words can take the prefix and explaining the meaning of the new words. A straightforward and engaging way to introduce this objective.
