Both those games sound like they would work!

One I've had success with in big and small classes is:
PICTURE RACE:
This works with small and large classes, split into several teams,
Arrange teams into lines.
At the front of the class provide each team with a sheet of paper and pencil
Collect the students at the back of the line.
Whisper a drawing instruction to them: e.g. draw a big tree (and perhaps later draw a monkey under the tree), etc.
Students whisper the instruction to each other in a chain. The student at the front has to correctly draw image.
Fastest team scores a point.
Each round, the player from the front of the queue shifts to the back, and all other players shift forward a place.

Hope you like that one!
Ron.
