    FREE Math Education Webinars

    NCTM has two new learning opportunities to collaborate with your colleagues from all over the country, no matter where you are. This month Webinar Wednesdays will discuss the different pendulum swings throughout the history of mathematics and implementing effective mathematics teaching practices with the newly published Taking Action series—now availiable after selling out completely at the Annual Meeting last month.


    Join us for these free webinars and share your insights before, during, and after the events on social media with the hashtag #NCTMLive. Join your peers in the mathematics education community and let's learn together!

    The Elusive Search for BalanceSMS_2901(1).jpg?r=1492627769989

    May 17 | 7:00 p.m. ET


    Taking place next week! This President's Message webinar will take a closer look at the ideas discussed in the February President's message.  NCTM President Matt Larson explores the different pendulum swings throughout the history of mathematics. He proposes that we seek balance and break the historic cycle of pendulum swings. We need to return to, promote, and implement in our classrooms the NRC definition of mathematical literacy. We want students to know how to solve problems (procedures), know why procedures work (conceptual understanding), and know whento use mathematics (problem solving and application) while building a positive mathematics identity and sense of agency.

    Taking Action, 6-8Taking Action: Implementing Effective Mathematics Teaching Practices

    May 24 | 7:00 p.m. ET


    This Author Talk webinar will engage teachers in activities drawn from the newly published Taking Action series. This new series will help teachers develop their understanding of the eight effective mathematics teaching practices found in Principles to Actions: Ensuring Mathematical Success for All. It will also give information about how to enact the teaching practices in classrooms and, in so doing, promote equity. The activities will include analyzing a narrative case, student work samples, and a video to help teachers understand how engaging in particular practices can support student learning. Download the handout packet and join author Peg Smith in just two weeks to take your teaching to the next level!

    In order to apply, teachers must submit either a 300-500 word essay or 1-2 minute video on the following prompt:

    The Internet provides students a vast resource for research and learning. Yet, navigating the beneficial and dangerous places online has been an ever-evolving battle. What have you as a teacher and your classes learned when it comes to cyber safety?

    More information about this opportunity can be found here:

    The application deadline is April 30, 2017 so it would be great if you could post this opportunity as soon as possible on your News page ( so teachers have ample time to prepare their applications.

    If you have any further questions, please feel free to contact me.

    Kind regards,

    Jason Linton
    Community Manager

The ATOMIC Mission is to ensure that every Connecticut student receives world-class education in mathematics by providing vision, leadership and support to the K-16 mathematics community and by providing every teacher of mathematics the opportunity to grow professionally.
