I will use Edmodo to send them examples of good designs and bad designs. I will ask them to evaluate and discuss why one design is better than the other.
In the spring I'm going to have them choose an historic building, and make a 3D model. I will use Edmodo to have them teach the class about the history of their building.
I would embed a file; however it is a SketchUp file, and you would need to have that application on your computer to view it.
I liked Today's Meet also. I can see using this as a warm up activity. Since I have a computer lab, this would work well. I would have a question on the board, and have them comment as I take attendance.
I would start class when everyone has made a comment, using a complete sentence. It's always ok to help and encourage your neighbor in my class, so no one is left behind.
