Great ideas! My grandsons are 11 and 13 now. I have made them a 'toy' that is going around now. It is a little like the Hacky Sack that I knew from days gone by. This is 2x3" and filled with sand, rice or beans. Idea is for them to toss it, kick it, and catch it. They learn to do an entire routine with the little sack.
Bean bags are always good to use for their garbage can basketball.
