I've had great luck with BINGO in my classes.
I hand out blank BINGO cards and a list of Medical Terminology word parts and ask that each student populate his/her own card using the list the provided.
I then pull definitions out of the hat- the students mark the word part with that meaning on their card.
Standard BINGO rules apply.
I usually have small prizes available- a bonus point, a pencil, an eraser, something like that.
