October 10: Graham Fletcher wrote about "Geometric Subitizing: A Different Kind of Number Talk." It certainly looks clever, and I hope teachers of young students who are willing to try it take a bit of a researcher's eye when sharing how the activity works with their students.

October 11: It's posts like this that exemplify the rewards I feel for digging through everything that gets shared each week. Joe Schwartz wrote about "Unknown Unknowns," in which by asking students to say everything they know about a figure he finds out so much more than asking them to solve a single problem.

October 12: A recent OECD report says "Math Students From High-Performing Countries Memorize Less, PISA Shows." Not too surprisingly, there's also an association between students who say they rely on memorization in mathematics and students who claim higher levels of anxiety towards mathematics.

Around the Math Ed WebThis week's #TCMchat focused on the article "Assessming Students' Understanding of Fraction Multiplication." Next week it's the #MTMSchat for the middle school crowd, and the free article to be discussed is "All Talk and More Action" by Maryellen Williams-Candek.
This week's Global Math Department meeting was "Teaching Ideas to Prepare Your Students for the AP Stats Exam" with Amy Hogan, Bob Lochel, and Doug Tyson. Next week you can look forward to "6 Hand Signals That Bring Learning to Life" with Ellie Cowen and Megan Nee.

Math Ed in Colorado
Elementary Mathematics Specialist EndorsementI am looking to recruit people interested in doing the work necessary to establish an elementary mathematics specialist endorsement in Colorado. Such an endorsement has been wished-for by quite a number of people in K-12 and higher ed, and we now have an opportunity to do the work in the coming weeks. From the COmath community, I'm especially interested in elementary teachers with extra mathematics training, like a math major or minor, or other specific preparation to teach mathematics. The committee will probably consist of 4-6 representatives from higher ed, 4-6 district math specialists, and 4-6 classroom teachers who have extra training and expertise in mathematics teaching. Volunteers from rural districts would be especially appreciated! Email me if you are interested and I will follow up with more information in the coming days.
Computer Science Standards Input MeetingsDuring 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
Math Day at Colorado State UniversityMath Day at CSU is Thursday, November 3. Math Day is a day of individual and team competitive mathematics for high school students, with scholarships available for high-performing students. The cost is $20 per student and registration is by recommendation of high school teachers. The registration deadline is Monday, October 24.
Teaching English Learners Workshop now in Bayfield, TooIf you have emerging bilingual students in your class, and you want to know more about helping them access mathematical content, there are now two upcoming workshops to attend. Rebekah Ottenbreit of CDE is offering "Teaching Math to English Learners" on October 18 in Grand Junction, and on October 20 in Bayfield. 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.
Job OpeningsFort Lewis College in Durango is looking for a non-tenure track lecturer with statistics experience.
CDE has two jobs which aren't math ed, but they might be of interest to someone who reads this. First, we're looking for an Assessment Principal Consultant who would oversee assessments for Grades 10 and 11. Second we need a Digital Literacy Instructional Specialist who would work in the department and with schools around issues related to ed tech and digital literacy.
