--teach him to type and be comfortable with writing software on the computer/ipad/whatever device.
--engage him in rewarding activities that work on the motor skills and core strength (swimming, martial arts, horseback riding, etc.). These don't necessarily feel like therapy, but they work like it. I think karate will be great for a kid like this, as long as it's an encouraging program (not hyper-focused on achievement).
I would not recommend stretching exercises for a kid with DCD until you've had an eval for connective tissue disorders-- stretching can make joint hypermobility worse.
