The past two weeks have gone smoothly, with attendance in the 7-8 range. Some of the new games I added are popular. I'm planning to introduce the self-tracking form this week. I hope to use it to find out what games they're good at and direct them towards ones that exercise other skills. I'm thinking of the workshop now as cognitive enrichment. Not sure I'll be able to measure any individual gains in the workshop itself (the tracking form may help) but it does provide a place where parents can consult about using this as a tool to help solve issues.
I'm going to start applying the theory to my own kids, actually. A teacher (non-Palmerston) recently used "ADD" to describe him (not in a negative way, she said she was that way herself), so I'm having him do all 12 levels of Ballance, the game I've recommended for that.
