This resource pack helps children understand how to choose between the articles ‘a’ and ‘an’ by focusing on the sound that follows, rather than the letter a word begins with. It includes a clear and engaging PowerPoint lesson that introduces the rule, explains common misconceptions and provides interactive opportunities for discussion and error correction. The accompanying tasks allow children to apply their knowledge by sorting pictures, completing sentences and correcting mistakes in context. This resource is ideal for whole-class teaching, small group interventions or independent reinforcement and comes with full answer sheets to support teachers and learners alike. Whether tackling simple examples or more complex words like ‘hour’ and ‘unit’, this pack builds a solid understanding of how and when to use ‘a’ or ‘an’.
