With ds7, when he was in 1st grade and going to 2nd grade for math, his 1st grade teacher noted on his report card that math instruction was mainly with 2nd grade. Then the 2nd grade teacher just filled out the math section of a report card for him. He did the 1st grade state testing at the end of the year (and got 100%, go figure - bet he boosted their average). In 1st grade he went 3 days per week to 2nd grade math, as that was all scheduling would allow without him missing specials. This year, the teachers knew ahead of time that he would go to 3rd grade for math, so they co-ordinated their schedules, so that he could go 4 days a week (again, the 5th day was too full of specials, which was out of the teachers control). I'm pretty happy with this - although I think he'd do just fine in 4th grade for math, we'll see how 3rd grade goes, for now.
