My DS broad score on WJIII was 145 Math. My DS in 3rd Grade, wrote on a school project what he would like to learn this year was decimals and square roots. What do you think if I tell him he could do Alex and the he can keep progressing until he gets to this. Do you think that is very far off? He is doing 3 & 4 grade math this year. Do you think that will just make his future math classes more boring? Should I just keep with the Mindware math books and the math olypiad questions.
