This is a PowerPoint based activity, perfect to practise different comparison structures.(as...as; ......than, not as....as; not .....enough) After you've given your students the theory on how to form comparative and superlative adjectives, it's time to put their knowledge into practice. Students should use the visual prompts to make comparisons in five categories: houses, animals, jobs, sport, cars. Introduce the given adjectives first, making sure students understand them, and then show the pictures and help your students talk and compare. There are three pictures and four adjectives in each category, so that students can use different structures for each slide. Have fun!
