I had a great day on Tuesday learning about new sites I could go to that will help me show math content in a new way. I created this list that will be ongoing. I am still working out the organization bugs. So far I have a list started of videos that reinforce math concepts. It is funny how I can say or demonstrate a concept and won't quite 'get it' but when I show them a video of the exact same thing I've been saying, they suddenly understand!
Great Video Resources for grades K-4 to help with math concepts.
