Thank you all for your responses. I think I will talk to the teachers about it. I don't really care about making any changes this school year but I'd like to talk to them about next year. Part of their challenge (and what also makes it a great school) is that it is very mixed grades and ability levels. His class is grade 3-8 and some kids are advanced for their age and others are delayed.

There are group learning activities but if it doesn't end in a worksheet, I don't see it. I only see what comes home in his folder. The extras take up a lot of time and they let DS do special things like read to preschoolers and help the K teacher with science presentations.

However, I'm concerned he'll get to junior high or highschool and not be prepared.
