Similar situation here... My ds is 9 and will be starting Saxon 8/7 w/pre-algebra in the fall for 4th grade (which I am sure he will fly through since he already has mastered much of what it covers, but I want to be sure that he doesn't miss anything)... we then plan to move to Jacobs Elementary Algebra, but he will only be 10. I am thinking that we may do a year of "fun math" between since he will be so young. I found the book "Beyond Base Ten" http://www.amazon.com/exec/obidos/tg/detail/-/1593633297/ref=ord_cart_shr?_encoding=UTF8&m=ATVPDKIKX0DER&v=glance to fill that time, and it looks like it would be a fun unit to break out of the box. He is a pretty gifted little guy who loves math, but I worry that at some point that he will struggle not with the math, but with the developmental growth of his brain and how much he can physically learn. Does that make sense? Even with the "fun math" year in between, he would still only be 11 to start Algebra. I'm still just in the "thinking about" stage... any thoughts?
