LearnZillion

LearnZillion is another site like Learning.com that allows you to set up classes and assign curriculum, etc.  But, like Learning.com, its hidden jewel is the online content it offers.   Sign up for free as a teacher and then you can decide if you want to use all the class management tools.  Or, you can just let your kids watch their great videos covering all topics in Math and Language Arts for grades 3-12.  The videos are simple animations, somewhat similar to Khan Academy‘s, but a little more professional.  They have a conversational tone and just enough dry humor to keep them interesting.  There are also playlists, grouping videos together for a common topic, and some quizzes.  This would be a great back-up if you just need a different way to explain something in math.  Also, one of the few online language arts sites I’ve found.  Good for grades 3-12 and utterly free.
