I created this for my ninensee students as a way to practice the “I think that…” pattern in Unit 2 of the New Horizon textbook. In this worksheet, students must unscramble the sentences into the correct order. Afterwards they must fill in the blank spots with their own opinion. (eg: I think that the best bukatsu is baseball.) I made this for a basic level English class, so feel free to use this sheet as a base and create harder questions.
Afterwards students can share their opinions with a partner and see if they agree or disagree with each other's answers. To make this more interactive, students could also stand up and walk around to see if they have can find a pair with someone who has the same answer as them. Since the class I made this for was very low level, we worked through each question together and after students filled in their opinion they compared their answers with the person sitting next to them, so that’s another way you could go about it.
This website has been so helpful for me, so I wanted to pay it forward and post some materials I have made. Hope this helps!
