Considering Kumon for my 7yo DS. He's bright, but struggling with concentration. He's not completing work at school and homework is a struggle. He's more than capable but just not interested. Wondering if something like Kumon may reignite his passion for school work, or if there's something else we could try? The teacher has suggested reward charts but I don't feel this is the best approach, I want him to do the work because he wants to, not because he'll get a sticker. Any help really appreciated - I don't want this to continue into a downward spiral
