Make an old fashioned bean bag – they can practice throwing for a couple of days to each other (we all know that won’t be exciting enough!)
Then you can take a piece of cardboard or a box is easiest, cut a couple of large holes in it (2 yr olds need larger holes, 5 yr olds smaller ones) and have them try to throw the bean bag into the hole.
When they loose interest in that – sit up some soda cans, water bottles or whatever you have and let them knock them down.
Someone was talking about turning cereal and other boxes inside out and letting the kids color the inside of the boxes. Karen
