A very simple warm-up or review game for younger classes.
Before class, use your amazing artistic talents to draw a person (preferably a caricature of yourself) hanging from a bunch of balloons over the ocean, where a shark is waiting. Try to draw at least 4 balloons per student in the class, so everyone gets a turn.
To play the game, each student gets a turn answering a question. After answering correctly, the student rolls a dice. The number on the dice indicates how many balloons the student can pop. The game ends when the teacher is in the ocean, or when every student has had a turn.
If you teach with a co-teacher in the classroom, this game is especially fun when you draw both teachers hanging from separate bunches of balloons. Each student gets to choose whose balloons to pop, giving plenty of opportunity for the teachers to ham it up and joke with the students, pleading for their lives, threatening extra homework if they’re the first teacher to get eaten, etc. If you’re artistic, it’s extra fun to change the cartoon’s facial expression as the bunch of balloons gets smaller!
