Google+SketchUp

google.sketchup.com by Barbara Duenk This website is free but there are levels that may be purchased. From what I've seen this is a lower version of AutoCAD type software. Although there are many high level (high school and up) things you can do with this software, there are many activities/demonstrations that apply for elementary levels as well.

This is easy to install. Once installed an icon appears on your desktop. There are many tutorial videos to watch but many begin at very high levels. Once you double click on the sketcup icon, you will get a screen that allows you to view videos or other tips and help pages. To get going click on "Start Using Sketchup" to bypass this page. The next thing I did was delete the person in the middle. I will demonstrate some key features in class.
