This activity helps children practise when to use ‘a’ and ‘an’ correctly before nouns. Pupils work through short word lists, fill-in-the-blank sentences and an error-spotting passage, giving them the chance to apply the rule in different contexts. The tasks are designed to reinforce understanding that it is the sound a word begins with, not just the letter, that matters. A quick and effective activity for targeted practice, starters or five-minute fillers.
