Has anyone used the beginning algebra curriculum? I'd love to hear comments on it.
My 7yo boy liked it and has finished it. I think it's good for basic algebraic manipulations (find the equation of a line through two points, factor a polynomial, solve a quadratic equation using the quadratic formula etc.), but a child who is gifted at math should probably follow up with an algebra book or course that is more rigorous, maybe AOPS including Alcumus or a textbook from the Dolciani series. (Or Singapore's New Elementary Mathematics? I am considering this. Has anyone tried it?)
