The attached is a review for Jin H Choi's middle school textbook, grade 2, chapters 4+5. My students have a test on this material next week, and my co-teacher requested a review class for them. I gathered them into groups and they filled out the worksheet together, there are some minor differences between the worksheet and the ppt but its not enough to derail the class.
There is a video in the middle of the lesson, I never had enough time to do it, it's just an emergency thing to pad out the class. When the students finish the review, they trade papers with a different group and then mark them, the team with the highest score usually gets candy (or pencils or something)
anyway, best of luck!
