So my youngest DS just turned 5 this weekend. He is starting on BOB books, which is fairly typical, but the kid really loves math. I have not been doing anything formal with him except Sonlight P4/5 literature. That is his "school" and we all love listening to those stories with him. But he begs for math. I got him a Critical Think Co. Mathematical Reasoning book (level 2) because he was begging for it and he has sped through it. He knows his math facts through 12. He can reason through things like today he told me 1 hour and 6 minutes is 66 minutes. 8+4 is 12 because 8+2 is 10 and 10+2 is 12. He can count by 10s and 5s easily and is starting on 2s. He can see groups of figures and group them in order to know how many there are without counting. It really is amazing how much he thinks about numbers, manipulates them in his mind and just plays with math.

SO...he will do RightStart for kinder but I don't know about starting anything formal until next year. I'm not one to rush it but this kid BEGS for that math book daily (even on the weekends)!! Do I just get him the kinder Mathematical Reasoning book because it is fun/colorful or start with RightStart so he can start thinking about math their way. He already does operations on his abacus, but we haven't done the formal curriculum with him.

OR...do i get him the fun book that he wants and maybe skip the first level of RightStart when we start formal school next year?

Stopping and letting him play isn't an option. He won't have any part of that. ;-) Youngest kid...wants to be like big bro and sis!!
