What is MyOpenMath?

MyOpenMath is a free, open source, online course management system for mathematics and other quantitative fields. MyOpenMath's primary emphasis is to facilitate the creation and implementation of online homework and assessment, although it also supports content delivery on a limited basis.

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.

MyOpenMath.com is operated by the non-profit organization MyOpenMath.


MyOpenMath.com is supported in part by financial and in-kind contributions from corporate sponsors.

Lumen Learning

Lumen Learning provides supported tools using OER, including Waymaker, an adaptive learning platform, and OHM, an online math homework site.

XYZ Homework

XYZ Homework is an IMATHAS compatible online homework system. They are an OpenStax Ally providing custom templates and coding for their math titles. XYZ Homework specializes in customization including printable eBooks and additional ancillaries based on OpenStax and other OER materials. They are also the online homework partner for XYZ Textbooks.


MyOpenMath operates using a "freemium" model. Use of the site is and will always be available for free.

For institutions wanting a service level agreement and data sharing contract, as well as access to additional administrative features, these are available for a low-cost annual hosting fee paid by the institution. For more information, contact sales@myopenmath.com

MyOpenMath does not provide direct student or instructor support services, regardless of your service tier.

MyOpenMath follows the data protection policies set out in our Privacy Policy and Terms of Use, regardless of your service tier. We will never sell your personal data.


Community-based support is available through active, 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 beyond what is available on MyOpenMath, then you should consider using a commercial homework system. There are number of homework sites that provide homework for open textbooks with support services. Some of these sites are MyOpenMath compatible, meaning most courses on MyOpenMath can be moved to that platform. This listing is not an endorsement of any of these systems.

Our History

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 supported service from the free, community MyOpenMath site.

In 2018, the non-profit organization MyOpenMath was formed to be the official entity operating MyOpenMath.


Operations of MyOpenMath is facilitated by a number of volunteers:

  • Cindy Moss
  • Jessica Kuang
  • James Sousa
  • Jim Smart
  • Patrick Carmichael
  • Roy Shahbazian
  • William Meacham
  • Everyone who participates in the Support Course forums assisting their fellow users

The question and course content on MyOpenMath has been created and contributed by faculty from around the country. They include courses created for the the Washington State Open Course Library project and the California ZTC Degree grant.

The development of the IMathAS platform that powers MyOpenMath has been supported by several grant projects, sponsors, and community contributors, including:
