DD9 and DS6 both have really enjoyed Brain Pop. Our schools have a subscription, but I believe some parts of it are also free. They find it very entertaining, and DH likes to ask them, "What is Moby up to today?" wink

I see it more as fun enrichment, but both DC have actually picked up quite a bit from enjoying Brain Pop. From time to time, they have surprised me by knowing something rather unusual, where I have asked them, "where did you learn that?" Sometimes the answer has been, "Brain Pop."
