This is a very interesting site that I think might have an elementary focus. I enjoyed looking at the content I checked out, and I can see that it might be useful in class. Maybe on a SMARTboard during an inside recess? Or for playing at lunch? Or perhaps there is a trip that fits with your curriculum?
I LOVE the video book reviews - these are dead simple to do! Perhaps you could do some of these?
Maybe you and your class could create and submit a virtual field trip to somewhere local and see if you can get it put it online?
The following description is from their homepage, located at http://www.meetmeatthecorner.org/:
MEET ME AT THE CORNER, Virtual Field Trips for Kids takes you to meet fascinating people from all over the world.
New educational, kid-friendly episodes are uploaded every two weeks. Included are links to fun websites and our Learning Corner with follow-up questions.
Check it out....maybe you'll find it interesting?
