Along with OpenEd, I have started using PBS, and their media Math resources. I then reinforce the videos with worksheets, discussion, games, and hands on learning. Fridays, I evaluate how much she has retained with a test. I can not say how much I love Flash Cards, for learning the math facts I mentioned above. We use an app, and that makes it just that much more cool. Cool Math, is another website, I used to use, and will be looking at it again for my daughter.
I will be looking at the Writing on PBS as well, though I love the Michael Clay Thompson series we have been using, and am already looking at purchasing it again for next year.
