How I Use It
I will honestly say that I do like parts of this app very much as the virtual tools are great for building some understanding. What didn't work for me was some of the tools within the app. The instructions regarding what students should be doing wasn't that clear and several sections never loaded.
For a free app, Autodesk measurement serves its purpose. A simple swipe can change and outcome and also help students to develop some sort of understanding. Again, I had a problem with it lacking instructions as well as several in-operable components within the app that were critical to understanding.
