My 2nd-grader qualified for the CTY talent search based on both his math and verbal scores. I'd like him to have covered all the math on the SAT by the 7th grade to increase the chances he will do well on the talent search then (and perhaps even qualify for the Study of Exceptional Talent, which requires an SAT of 700 in math or verbal). Currently he is doing Singapore Math 5A after school. What math curriculum have people used to have their children ready for the SAT in 7th grade?
P.S. He is too willful to let me "afterschool" him in math more than about 2 hours/week. He spends at least as much time chasing his 4yo brother in circles around the house. I don't think I am "hot-housing" him.
