Although I recommend charades (or “gesture game”) for What are you doing? or What do you want to do? (members bonus theme) I’ve never found a way of doing it that I was totally happy with. In one of the workshops this week I think I might have found it:

1. Put the kids in two groups.
2. One person from each group comes to the front.
3. Show the two people at the front a mini card
4. They gesture to their group.
5. The quickest team to answer wins.
6. Repeat from step 2.

Adding in the competition of having both teams doing it at the same time really turns up the pressure and gets the kids shouting things out. Adrenaline is a very nice motivator! You can of course use it with any of the GE themes that have gestures, which is just about all of them!
