• Start out by making a list of activities that you think your child would particularly benefit from.
• Make sure the activities are fun and feel like adventures rather than chores.
• Create challenges in several categories: physical, academic, behavioral (chores, manners, etc.) and skills. I picked projects that required dedication and long periods of focused attention since that is something my child finds hard.
• Pick activities that are just outside of your child's reach, but not impossible.
• Allow your child to come up with a few ideas for challenges.
• Repeat challenges that are particularly tough for your child. Start out easy and increase the expectation each time.
• Spread the challenges out by type and difficulty. That way, no week feels too daunting or too easy.
• Give rewards. Acknowledge a hearty attempt as well as full accomplishment, based on the idea that effort is what really counts. I gave my son a small prize for five attempts in a week and a slightly larger reward for five successes.
• Stay positive. Keep the mood light and reward effort, trying not to criticize "failure".
