What is MyOpenMath?

MyOpenMath runs on the open source, IMathAS platform, providing free hosted use of this platform in support of free, open textbooks like the ones listed on OpenTextBookStore.com. The intent is to provide classroom use of the platform, without any required cost to students, for schools wanting a managed install of the IMathAS platform, and to provide students self-study opportunities.


Community-based support is available through open support forums and training videos. MyOpenMath does not provide direct support for instructors or students.

If you are in need of more comprehensive support services, then you should consider using Lumen Learning's OHM platform. Lumen's services include curated course bundles with regular updates, faculty training and support, LMS integration support, large scale adoption and administration support, service level agreements a nd backups, and long-term access to course data. The support fee typically costs less than 10% of what students currently pay for commercial products (yes, we mean 90% less).

How/Why is it Free? Our Story

It is always concerning when you visit a website that offers a free service. What's the catch? Are you going to be advertised to? Get forced to pay for service in a year? To address those concerns, here is a bit of info about MyOpenMath's history and business model.

MyOpenMath was born out of free, open source software developed by David Lippman, a community college math professor in Washington State, starting in 2005. With a little grant support and a lot of his free time, David ran a state-wide installation of that software at wamap.org. Faculty from around the state got involved, and collaboratively contributed much of the question content now found on MyOpenMath. Out of the Open Course Library project in Washington, several complete courses based on open textbooks were created. Other folks got involved, including James Sousa from Phoenix College who contributed a huge collection of questions tied to his video examples.

In 2011 David started MyOpenMath as a way to share with the world this software system and all the great content that had been built around open textbooks. He self-funded the site for the first year, then joined forces with Lumen Learning, which had been using MyOpenMath with the Kaleidoscope Project. In 2017, Lumen split off their own version of MyOpenMath, called Lumen OHM, to help differentiate their low-cost supported service from the free, community MyOpenMath site.

David and Lumen both feel very strongly that a free community version of MyOpenMath should always exist, without advertisements. They are also committed that all the content remain open as well, so it could be moved to a local install of the IMathAS software if desired or needed. For now, Lumen is providing financial support for MyOpenMath. In the future, MyOpenMath will likely explore a "freemium" model, in which institutions will be able to pay an annual hosting fee in return for a basic service level agreement and data sharing contract, as well as access to additional administrative features. MyOpenMath will never provide instructor support services. David's intention is that students will never be directly charged on MyOpenMath, as ensuring student access to high quality materials is our number one priority.


While Lumen Learning now funds MyOpenMath, the development of IMathAS and the content has been supported by several grant projects as well as the time, effort, feedback, suggestions, and dedication of its users. Grants from the Washington State eLearning Council and the Transition Math Project helped develop the platform and create a large set of content.

Courses developed for the Washington State Open Course Library project are a basis for many of the open courses found on MyOpenMath. Others were contributed by faculty, including James Sousa from Phoenix Community College. Many of these courses were improved by contributions and feedback from faculty involved in the Kaleidoscope Project.
