I've got a piano/ chess kid. DS8 is less interested in chess these days... music is his passion.

How about a sport? Our son really enjoyed karate - they memorize katas and that was right up his alley. I know UCSD was running a brain development study on children and karate was one of the enrichment activities they were using in longitudinal studies.

We recently switched him to swimming just for an easier schedule. He enjoys that- swims with a USA Swimming Team and gets to compete. It's not about winning every race because what they stress is improving by dropping time. And it's a life skill (everyone really should know how to swim).
