I first watched a video by the authors of the demos. I found this to be a great introduction as to what the demos offered to teachers and students. The material on the website was well organized. You can find what you need through a key word index or demo collections based on the subject matter.
The quality was presented in a way where I could interact visually with the material. I found this to be very useful and the content was accurate.
I think this website helps teachers and students so much because these demos serve as a way to visually show students a new approach to learning. Now teachers have a powerful tool to demonstrate mathematics in a way where its fast and much easier to teach.
I think at first it’s a bit overwhelming but once you get started it’s worth it because the information is shown in a way where you can interact through activities where you can actually see your work being done through technology.
