You will need:
Two balls per pair.
– The students face each other in pairs. One holds two balls in his hands (at arms length), the other has his arms down by their side.
– One ball is released.
– The ball must be caught.
Gradually make the game more challenging. The student catching can have his arms behind his/her back, the student holding the balls can hold the balls lower before the ball is released or both balls can be released at the same time.
