How very sweet of your wife to do all this for the seniors! I remember my piano teacher would have me and her other students perform for the seniors at the rest home, playing the hit parade songs they all grew up with when they were younger. It always made them so happy. Not 'til I was much older did I realize just how important that was to them.

I just thought of another thing ... what if you had them make game pieces out of clay or wood? They could end up making a set of checkers and a checkerboard, for instance, that they could use later on to play with each other.

Or maybe you could get them into gardening, from the seed phase to the pruning phase, etc.

Or they could do a group project, like a quilt.
