We are using this class as a supplement to what we are doing at home. Basically our situation is: DS does not want to homeschool full time. We are looking for ways to make his mornings at school a little more interesting. He has all specials and math in the mornings. The afternoons he comes home. Up until now, I was sending in math work for him to work on by himself during math time. He strongly preferred to work with other children, so we were looking for a way to do that. We are also hoping to give him a bit of a "resting" point as he tears through the curriculum at lightning speed. At his current rate, he will doing algebra probably next year, so we are looking at this 5th grade math class as a way to make sure he's really got all of his gaps filled. He will NOT continue with this group next year. And this class will stop learning topics in April as they spend a month preparing for state test review. So, we are looking at about 6 months with this class.
If you have him in school for social reasons and he's doing math with you at home then I'd keep him with the younger kids. I don't think that 5th grade Everyday Math is going to fill any holes if he's going to be ready for algebra next year--you'd need 7th grade math/prealgebra for that.
