I draw up the same grid on the chalkboard and then put the students in 4 or 5 teams.
E=easy question (2 points)
M=medium (4 points)
D= difficult (6 points)
You can see the questions I used below the grid. They are directly from the study paper that I gave my students for the midterm exam (only speaking, 1-1 with me).
Then, there are special squares:
T=Typhoon (lose all points)
H=Hurricane (choose 1 team, -5 points)
V= Vacation (+5 free points)
I go around the class from team-team and then the students have to choose a square. I write up what letter they get and then ask a question/add points, etc. At the end, the winning team gets a prize of some sort. It's an easy, fun way to do review and I always add additional commentary for almost every answer. Like, if it was a A/B/C..answer, or how it could be improved, etc.
