eToolBox is about as cool as Sima...

I really enjoyed reading Wissahickon School District's eToolBox that I found on the website full of edublog awards.  The site is full of resources for integrating technology in the classroom.  One particular link lists the Top 10 Web 2.0 Tools for Young Learners and it discusses blogs and wikis.  I think both of these are wonderful tools for elementary classrooms.  They can be useful for all subject areas and language learners.
