## Around the Math Ed Web

Next week NCTM kicks off it's first #MTchat, which rounds out the lineup of article-based chats along with #TCMchat and #MTMSchat. These chats may not have the impact and scope of a conference, but this gives members have a way of interacting with each other and their professional organization on a much more regular basis.Our 1st #MTchat is getting closer. Read the topic article & join the chat on 9/28 https://t.co/Qx5GWMapHr #MathChat pic.twitter.com/htBqixne67— NCTM - MT (@MT_at_NCTM) September 23, 2016

If it's Tuesday night, it's Global Math night. Last week was "Getting Students Talking... Open Questions in the Math Classroom" with Mishaal Surti and next week is "3 Reasons Kids Don’t Know Facts and How to Help."

On the conference front, both the Phoenix and Philadelphia NCTM Regional Conferences are approaching, as is the new Innov8 Conference. NCTM is also asking for proposals for next year's regionals, due December 1st.

### Math on the "Planes"

As far as I know, there are still spots available, so register now!### Boaler Book Study

Cassie Harrelson of Aurora Public Schools will be facilitating an online book study on COPilot with Jo Boaler's book Mathematical Mindsets. Participants will need to purchase the book and register online ($45 for CEA members, $145 for non-members). The book study begins October 2nd and will last for 5 weeks. Let Cassie know if you have any questions!### MSP Grants

If interested in applying for a Mathematics and Science Partnership grant, please submit a letter of intent via SurveyMonkey by Oct. 5. Applications will be due Monday, Nov. 14. For additional information and to access the application, please visit the MSP webpage.### Professional Learning Opportunities

Do you have English learners in your class? Do you want to know more about how to help them access mathematical content? Rebekah Ottenbreit of CDE is offering "Teaching Math to English Learners" on October 18 in Grand Junction. The all-day workshop will offer tools and strategies for making math more accessible to English learners through teaching the Colorado English Proficiency (CELP) standards. You can register for the workshop on the CDE website.Colorado School of Mines will offer weekly Saturday training sessions focused on Computer Science Principles. They are following the Code.org curriculum and started with Unit 2 on Saturday, September 10, but I think it's fine if you jump in late. You are welcome to attend any of the units/lessons that you think might be valuable, whether you are using Code.org or not. Details can be found at the C-START website under the CS Principles link.
