Whose hat is this? Powerpoint Warm up Game.

A powerpoint presentation I use in the revision classes for "Whose (thing) is that" grammar point.

I use this as a warm up before the lesson, but this could be used as a review for the end of a lesson.
The powerpoint goes through the grammar point, with brief Japanese explanation.
I usually have the students repeat what I say, and raise their hands to answer any questions.
