What could a tent look like with different lengths for its height and base? In this activity, investigate and graph relationships between the height and base of a dynamic tent. Inspired by Isosceles Triangle Graphs v4 by Steve Phelps: https://www.desmos.com/calculator/yxqay82kh7
What could a kite look like with different lengths and widths? In this activity, investigate and graph relationships between the length and width of a changing kite.
Thanks to Dan Meyer and the team at Desmos for collaborating with ITSCoRe to develop these activities.
Heather Johnson, ITSCoRe project PI, highlighted the Cannon Man Activity in her Webinar for the Global Math Department (@GlobalMathDept)

Thought about trying one of the ITSCoRe Techtivities?
Want to help students to move beyond what graphs look like to what graphs represent?
In a February 2018 Edutopia blog post, Heather Johnson shares how the Cannon Man Techtivity can help.

We have a set of 5 dynamic computer activities, “Techtivities,” developed in collaboration with Dan Meyer and the team at Desmos.
The Techtivities link animations with dynamic graphs, in innovative and exciting ways. Students working on the Techtivities can have opportunities to form and interpret relationships between attributes capable of varying and possible to measure.
In this video clip, Heather Johnson talks about the Cannon Man Techtivity:
So far, the Techtivities are available in three languages:
The Techtivities are free for others to use. We hope you will try them and let us know what you think!
