My lesson plan includes a review drawing/coloring activity for the previous lesson (Info gap activity, using the words "long, short, tall, big, small", as well as parts of the body and colors.) The students tell each other how to draw a made up animal. Need to make sure students have coloring pencils and paper prepared. Also, assess their reading ability before doing this activity. Perhaps you can adapt it.
My other activity also went over very well. A version of the game of telephone using the powerpoint slides and having all but the first student in the line face away from the screen.
Have fun!
P.S. I just added a photo of the board game in the back of the book where the students say the phrases and play RPS to advance. The directions are in the teacher's manual. It went over very well and is good for about 10 minutes of class time or so.
