Here's a wonderful example of a truly redefined lesson. Below is an interactive Thinglink that showcases Chrome Extensions. Click on any one of the images below to view a snippet of what that extension could do for you and access a link to add it to your list of extensions.
On a second note ... just think what you could create in Thinglink for yourself and your students! Could you do a Thinglink with a picture of your classroom and links to fun facts about each student or maybe a link to each student's email? How about a Thinglink with a picture of your classroom with tags demonstrating a few key places - like where to turn in late work, sharpen your pencil, recycle, and more! How about coaches ... what could YOU try?
