What do kids transition to for high school math after doing Singapore math through 8th grade? Do you have any recommendations, or know what a lot of our customers do for those higher level grades?
They can do Geometry, and then Algebra 2. If you’d like video or online teaching, you could do HighSchoolMathLive or Thinkwell. For students who excel at math, you could use The Art of Problem Solving. If you want to teach them yourself, the Geometry books by Jurgenson et al and Algebra Structure and Methods books by Dolciani et al are good.
