I use this material to show the grammatical rules of comperatives. With this I can show the three rules (-er, more, irregular adjectives). At first, the rules are presented. Then for each rule you can see an animated sceene. After the explanations the multiple choice section is given for the students to answer. In test section again, animated gifs are used. I hope it will be useful for your lectures.
