The talented Candy McGregor and Megan McQuinn built an incredible bank of tools on their Google Site (linked below). Here are some of the ones I was able to find.
Google Site of Tools:
1) I viewed the Live Webcams tools:
-great way to show students actual locations around the world
-show kids live animals
-virtual field trips
-This tool just changed my life!
-Allows you to do anything you ever wanted to do to a PDF: convert, edit, rearrange, etc.
3) TakingIT Global
-Connect students to global issues like human rights, environment, poverty, education, etc.
-Students have access to a global community & resources to begin to solve the problem
