[MOSAIC] literacy websites

[kmglass at optonline.net]

Hi All,
I am a graduate student currently enrolled in a literacy and technology class.  One of our assignments is to create a litearcy website for elementary school students.  Since I am not teaching yet, I was wondering if those of you who are can offer any good websites that I can link to from the one I will be creating.  I'm looking for fun, interactive websites that have either literacy-related games, online books, and other online activities elementary aged students would enjoy.   If anyone has any suggestions that would be great, thanks!!
