For a further challenge you can state that the children can only move in a certain way to collect the balls (e.g. hopping, jumping, on all fours, hopscotch, starjumps, etc).
3-5 yrs: show the children how to throw underarm and also overarm from the shoulder.
5-7 yrs: encourage that the children throw overarm from the shoulder. They can point with their non-throwing arm to help them with aiming and they should follow through with their throwing arm as they transfer their weight forward. To give them more of a challenge, they can only throw balls back on to the blanket from no closer than 2 metres away.
Teach the children to catch the balls as they bounce out of the blanket.
3-5yrs: keep eyes on the ball, get their body in line with it, hands together and cupped or closed around it. Secure ball by bringing it inwards towards body.
5-7yrs: all of above, plus place hands together with fingers pointing upwards for a ball arriving at chest height and fingers pointing downwards for a ball arriving below chest height.
