Comparative and superlative activity
I started with some silent lecture to show the rules of making comparative and superlative forms of adjectives to the students. About 10 min of the silent explanation is followed by an activity which I might call One card. You will easily find out how it goes in English class through the PPT. Also, don't forget to surf Guinnessworldrecords.com which is an authentic site full of superlative forms. Enjoy!
