I like to do this in my kids and teens classes as an opening routine. I use it to review the vocabulary from the previous class.
OBJECTIVE: Review previous vocabulary
MATERIAL: A white/blackboard. Dice
TIME: 8-10 minutes
VARIATION I: Draw or Act
ACTIVITY: Split the class into teams.
VARIATION II: Draw/ Act/ Describe
ACTIVITY: (for a bit more advanced classes)
Good luck! Let me know how it works for you and if you have any special touches that I can try in my classes:
