Who doesn't love Sesame Street?!
You can get a LOT of wonderful, free resources from Sesame Workshop. I contacted someone directly and was able to get the hard copy versions of the Sesame Workshop programs at no charge. Also, there are many educational videos on Sesame Street's YouTube channel.
I just thought I'd share this cute video about the word "cling." Anyone ever feel like Jude Law when at school? I know I do!
