Kid games that my son who is 11 and his friends love, and which we often do as an Ice breaker is toilet roll mummies... teams of two players.
Each team equipped with a large roll of toilet paper.
One player stands up straight, with his arms by his sides. legs together. The second player has to roll toilet paper around him from top to bottom (or vice versa) without breaking the toilet paper if possible. So that his friend becomes a mummy.
