As far as liking school goes...
I think that overall he likes it. Certainly he's getting things like recess (socialization time with peers), Spanish, Art, Gym, etc., that he wasn't getting before and wouldn't have got if he went into K.
We've observed some negative behavior with homework that I mentioned before. Things that he obviously knows that might be 8 math problems he'll take FOR-EVER to do. Finding the right motivation for him to do that work is tough, but we are sometimes successful with it. When he's motivated to do it, it's done in less than 5 minutes. I think it's important for him to do enough practice work so that he's proficient with the concept, but at least right now that's always the case.
Kriston, it's hard to tell if the behavioral issues are due to a long day and being young or not. We're not sure. DW always says that he behaves exactly like he's watched too much TV. That analogy of having to watch a movie in slow motion when you already know the ending... and the we get a boy who half the time is bouncing off the walls when I get home.
At any rate, this forum is at least a place where I can vent!
Thanks.
