I was recently introduced to http://www.learner.org/ because I was interested in finding Destinos, a Spanish immersion program, for Haley. There are so many resources on that site. I haven't even had the chance to look through it all. Haley and I have been enjoying Destinos, though.
I also love http://www.homeschoolbuyerscoop.com/ Haley has not been liking Saxon 78 very much. She does it without complaint but prefers to do Singapore Challenging Word Problems or Hand On Equations. So, when Homeschool Buyers Coop came up with a discount on Thinkwell courses, I decided that if the discount went far enough, I'd get PreAlgebra for Haley to try. She is really liking it, though she laughs at the man giving the lectures.
