Lukemac- Grinity is totally right, just get out the camera! We sent a video of our then 5 year old playing Pokemon cards with dad and playing Monopoly, after the urging of people here. It doesn't have to be a complicated math worksheet. Most 5 year olds can't play complex board games and really can't do the math, or explain their rationale for why a water Pokemon has a better hit on a fire Pokemon or whatever crazy thing he was jabbering about!
