I decided to create a page on my blog designed specifically for online resources. These include some of my favorites: Starfall, ABCya, and Game Classroom. Most of these specific links are geared towards Kindergarten, however; I know that Game Classroom has K-6 activites. As I find new sites I will continue to add them to that page. The page link is at the top under KinderLand or you can click here! http://kinderlandofles.blogspot.com/p/online-resources.html
