My 10 yo DD is finishing up EPGY 5th grade math through CTY, and although we may just move on to 6th grade, I am looking at other options as well. Which curriculum is really stupendous? Art of Problem Solving? Elements of Mathematics? Thinkwell? I am looking for something in the pre-algebra range. DD is not a particularly mathy kid -- more of a word girl, but she has liked EPGY and found is sufficiently challenging, although not too much so. I am looking for something that is really engaging, inspires creativity, etc., not necessarily the most rigorous, mathy thing out there. Does anyone have experience with these programs they would be willing to share?
