That's so great SPG! So glad that DS is liking his school, from what you said about I assumed he would love it. It really is amazing how quick they pick up math concepts sometimes. DS6 has been into Khan academy and really enjoys that. Has your DS tried that site? Maybe not so much during the school year but during the summer some. DS only really looks at it on weekends as the weeks are so busy! But Math Olympiads is over in a couple weeks so that will free up some time. Last week we had yet another snow day and DS somehow learned multiplying and dividing fractions and got up to the linear equations. He was really into it, and trying hard to improve his streak and get badges. Kids are funny sometimes.
