This activity helps children practise using the suffixes ‘er’ and ‘est’ to compare and describe. Pupils are encouraged to spot mistakes, decide which sentences are correct and then complete sentences by adding the correct ending. The tasks build an understanding of how adjectives change when comparing two things (taller, quicker) or when describing the most (tallest, quickest). This makes it a useful activity for reinforcing grammar rules while also giving children the chance to apply their knowledge in writing. It’s ideal for short grammar practice, as a starter or for targeted revision.
