This Week in Math Ed: October 21, 2016

Math Ed Said

October 14: A story in BBC News called "Maths becomes biology's magic number" says the future of biology research will involve a lot of mathematical modeling, and well-trained researchers who know how to avoid pitfalls of working with big data.

October 16: People were sharing new youcubed videos that answer the question "What is number sense?" These Jo Boaler productions demonstrate flexibility in calculations and come in both English and Spanish.

Note: If liked the youcubed number sense videos, you might really like Cathy Fosnot's "What is numeracy?" video:

October 17: Wendy Menard was featured in the MfA Teacher Voices blog with "Enrich and Enhance Your Professionalism through Blogging." Like so many of us, she's experienced both individual and community benefits through blogging and sharing with others about math education.

October 19: An article in Slate called "How technology can facilitate classroom discussion" (originally seen in The Hechinger Report) looked at Desmos's Activity Builder, Classkick, and Pear Deck, three apps that have added features to make technology use in the classroom more social.

October 20: Ibram X. Kendi's article "Why The Academic Achievement Gap Is A Racist Idea" makes the claim that achievement gaps don't just measure racism, but even the idea of an achievement gap conditions us to think in terms of racial hierarchies, which have a long history in American academia.

Around the Math Ed Web

Did you miss last week's #MTMSchat? If so, you can scroll back through these tweets and see what people had to say about Maryellen Williams-Candek's article, "All Talk and More Action." Next up on Wednesday: #MTchat.

Gail Burrill at the 2016
ASSM Annual Meeting
Global Math last week featured "6 Hand Signals That Bring Learning to Life" with Ellie Cowen and Megan Nee. Next week, Gail Burrill will be presenting "Reasoning from Definitions & Theorems: An Important Calculus Practice."

James Middleton is giving a webinar on Wednesday called "'Why Should I?' Insight Into the Choices Students Make Regarding Mathematics Engagement" as part of their Innov8 series.

There is an ASCD webinar on Thursday called "Lesson Imaging in Mathematics and Science: Mindfully Planning for Inquiry Instruction" with Michelle Stephan, David Pugalee, Julie Cline, and Chris Cline.

If you prefer to do your learning in person, go to Phoenix! On Tuesday NCSM is holding their Fall Leadership Seminar prior to NCTM's Conference from Wednesday through Friday.

Research Notes

Are you a professional development facilitator who works with elementary teachers? You might be interested in participating in a research pilot of some geometry materials from a project led by Tim Boerst, Kara Suzuka, Deborah Ball, and Hyman Bass at Michigan, with partners at the University of Denver and AIR.

Three new articles have appeared for the December 2016 issue of The Journal of Mathematical Behavior:

Math Ed in the News

Math Ed in Colorado

Colorado Academic Standards Survey

If you missed the announcement a few days ago, here it is again. Please reply to the survey by November 13!

CDE invites educators, educational leaders, parents, students and the general public to share their perceptions of the Colorado Academic Standards through an online survey available through Nov. 13. To participate, click here.

The results of the survey will inform the department’s planning for the upcoming review and revision of the standards, required by Senate Bill 08-212, known as Colorado’s Achievement Plan for Kids (CAP4K). The law requires a review and revision of the CAS on or before July 1, 2018 and every six years thereafter.

In addition to the survey on general perceptions of the standards, CDE will launch an online feedback system in November which will enable all educators and others to provide specific feedback on every expectation within the 10 content areas included in the Colorado Academic Standards.

In early 2017, CDE will provide comprehensive information about the timeline and phases of the standards review and revision process as well as information about how to become involved.
The survey and online standards feedback system can be found at General questions and comments about the review and revision process can be sent to

COmath Calendar

During a CCTM board meeting a number of us were discussing ways to help bring Colorado math educators together. One idea was to have a centralized calendar, not just for CCTM events, but for all events of interest to math educators in Colorado. You can access it here:
If you have an event you'd like to add to the calendar, email to submit your request.

Math Day at Colorado State University

The deadline to register for the CSU Math Day is Monday, October 24!

Computer Science Standards Meetings

During the 2016 legislative session, the Colorado General Assembly passed House Bill 16-1198 requiring CDE to develop academic standards for computer science for secondary students. The new law allows districts to elect to adopt these standards for their high school students. These voluntary, secondary computer science standards must be adopted by the State Board of Education by July 2018, and CDE is hosting three stakeholder meetings in October and November to engage a broad array of stakeholders to inform the development process:
  • Monday, October 31 in Pueblo
  • Monday, November 14 in Denver
  • Thursday, November 17 in Grand Junction
There will also be a webinar on Monday, November 28 from 3:30 to 5:00. For more information and to register to attend any of these meetings, see the announcement on the CDE Standards and Instructional Support webpage.
