Snowball Battle is a great game you can use in any ESL or EFL classroom with students ranging in ages from 6 to 106.
The game is extremely easy to set up and use. Simply give each student in your class a few toys that can either be stacked on top of each other or connected to each other.
Have your students sit in a circle and each time one of the students speaks they must add a block to the tower (another layer to the snowball).
After the student has successfully used your target language and added a layer, they must pass the "snowball" to the student next to them who must then repeat all of the words or sentences their classmates said before they received the "snowball".
Then that player must add a new layer of their own and pass the "snowball" to the next student in the circle.
