Who We Are

This project is led by Dr. Karl Kosko and Dr. Rick Ferdig at Kent State University. It is funded with a grant from the Martha Holden Jennings Foundation.

MathApps appreciates the feedback of our partnering teachers and administrators to improve the MathApps website.


What We Do

MathApps is an information, non-profit, and educational resource for individuals in the mathematics education community. MathApps seeks to provide a robust collection of information regarding existing mathematical apps for teachers, enthusiasts, and other individuals in the mathematics education community.

Our Team provides an objective review of each app, offering an initial viewpoint. Our community (anyone who joins the site for free) also provides links to apps, implementation suggestions, stories from personal experience, and unique insight to our reviews. This creates a robust analysis of each app’s potential and actual performance in the classroom.
