Two New Techtivities: The Dynamic Tent and The Changing Kite
Two new Techtivities are part of the collection:
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.
Tried these activities with students? Share your experiences with us.
Thanks to Dan Meyer and the team at Desmos for collaborating with ITSCoRe to develop these activities.
ITSCoRe Techtivities Highlighted on the Global Math Webinar

ITSCoRe on Edutopia
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.

Networking Theories to Design Dynamic Covariation Techtivities for College Algebra Students
Heather Johnson, Evan McClintock, Jeremiah Kalir, Gary Olson, University of Colorado Denver
We share our work to develop opportunities for undergraduate students to engage in covariational reasoning.
Building from the work of mathematics education researchers (e.g., Kaput, Thompson, Moore), we developed a suite of Techtivities—free, accessible, digital media activities linking dynamic animations and graphs.
Using a Cannon Man Techtivity to illustrate, we provide four key design components and three theoretically based design principles underlying the Techtivities.
To inform design both within and across the Techtivities, we networked theories of different grain sizes: Thompson’s theory of quantitative reasoning and Marton’s variation theory.
Developing Techtivities for students in the gatekeeping course, College Algebra, we intend to expand students’ opportunities to employ covariational reasoning.
We discuss implications stemming from students’ opportunities to use free, accessible digital media activites, such as Techtivities, to promote their covariational reasoning.
Introduction to Our Techtivities
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!
