A presentation I whipped up.
Students have to be quick - they have 10 seconds to state their preference/like/dislike/opinion and use the correct form.
After, students can use a survey card and go around the class surveying opinions and then reporting back.
Works well and will get students talking!
This is a nice template to use to get students stating their opinions on things in English.
Also see our presentation materials with students giving presentations on the pros and cons of things.
