There are many ways to get involved as a mathematics educator in Colorado, including a listserv, several organizations for teachers and supervisors of mathematics, and events you can attend.

CoMath Listserv

Latest Update | Update Archives

CoMath is a listserv designed to bring content, news, and information to support quality mathematics education to educators in Colorado. CoMath is Colorado's original social network for mathematics educators, and owes its origins to rural math teachers from around the state who started the listserv in the 1990s. Today, CoMath generally features:

  • 1-3 posts per week from members with information about events, professional learning opportunities, job postings, news items of interest, or questions for the field
  • Regular posts from Raymond Johnson, CDE Mathematics Content Specialist, about the latest in mathematics education
  • Moderated, non-commercial content

To sign up for CoMath, or to have an item included in a CoMath Update, email Raymond Johnson.

Colorado Teacher Organizations for Mathematics Educators

CCTM is an affiliate of the National Council of Teachers of Mathematics (NCTM), the largest professional organization of mathematics teachers in the country. CCTM serves its membership by hosting an annual conference, publishing a journal three times a year, providing grants to communities of learners, recognizing outstanding teachers and teacher leaders with annual awards.
