When I look at the curriculum (everyday math), I just don't see how I can put him in 4th grade math next year. There is very little that he doesn't know. Yes, there are a few things. And yes, he is still slow with his facts. But those are the only things in the way. When I look at the 5th grade curriculum, I see that they review 4th grade for the first few units. Shouldn't that be enough for him? Do we need to hire a tutor? I'd love to hear from anyone else who has done a radical subject acceleration.
