Table Bowling

If you have a small wedge around your school o r facility consider using it as a bowling alley. I found a box that it fit inside of and can always take the wedge out to use for positioning.

Just add a little Velcro to attach the balls so that children or adults with developmental disabilities can simply give it a push. I like using this in a group because each person can take a turn going 2-3 times and then watch someone else take a turn.  It worked really well when I asked a lady with hemiplegia to take turns pushing with right and then left. She usually refuses to use the spastic arm, but she didn't seem to mind when I kept moving the bowling alley so that she alternated which arm she used.
I used 2 balls that each made fun sounds when rolled.
