That's a difficult question to answer because so much depends on the specifics of your school and the pull-outs as well as any LD that your DS has. Since you are proceeding with repeat testing, I would be inclined to get a clearer understanding of his issues before approaching the school. At our school, 2nd grade math starts incorporating increasingly heavy writing requirements and it may backfire as far as your DS' attitude towards math if you put him in the pull-outs without special accommodations if it turns out that he needs them. Furthermore, you can absolutely acquire knowledge/skills in much of elementary math without formal teaching/curriculum. In fact, that was how DS in particular picked up much of the elementary math. I am referring to activities like shopping, baking, cooking, and games, etc.
