We were in the same situation at this age. After a few weeks in 1st they put our ds in 2nd for math and L/A. In 2nd he went into 4th. In our district 4th is where you get the drills. 100 multiplication and division problems up to 12 in 5 minutes. When he was in 3rd he was in 5th math and L/A. At the end of this year he really soared. The school at this point was out of resources. They came up with a plan but it fell apart during the summer and the start of 4th. We started AoPS pre algebra this year at home and then switched to a private school where middle school starts in 5th.
Take it one year at a time and go with your gut. When you get something in place, enjoy the breather. Work at home, make it fun. Give him a hand and take his lead when he decides to run with it.
