You will need:

Tennis ball or rolled up socks
5 discarded juice bottles, 1⁄4 filled with water
Marker for the throwing line
Boxes or chairs to alter the height of the targets

Instructions:

Set up your targets (bottles) in your space, ideally at different heights and distances. They have a bit of water in so that they don’t blow over.
You can use chairs boxes etc to alter the height.
Set up your throwing line so that you must use the overarm throw to reach all your targets. You can go closer or further away but measure the distance to the first target.
You have 5 opportunities to knock over as many bottles as possible using the overarm throw technique, you get 50 points per bottle and a bonus of 100 points if you knock them all down.
If you only have one ball, or item you can go and collect it each time, as long as you only have 5 turns.
