Collaboration and Chat: NCTM + TI


Texas Instruments (TI) and the National Council of Teachers of Mathematics (NCTM) have collaborated to develop classroom activities that they've just unveiled at the NCTM Regional Conference now underway in Indianapolis.

Each freely downloadable activity comes with a companion guide:

  • Domain and Range 2
  • The Pentagon Problem
  • Solving Systems by Graphing
  • Boxplots Introduction

TI and NCTM will mark the collaboration by hosting a Twitter chat to explore effective teaching practices that support standards-based learning. Participants include

  • Peter Balyta, Ph.D., president of TI Education Technology
  • Gail Burrill, NCTM Past President
  • Jill Gough, Director of Teaching and Learning at Trinity School (Atlanta, GA)
  • Jennifer Wilson, teacher at Northwest Rankin High School (Flowood, MS) and a Presidential Awardee for Excellence in Mathematics and Science Teaching
  • Jon Wray, current NCTM Board member

Join the chat Thursday, 6 November between 6-8 p.m. (ET) by tweeting with the hashtag #NCTMP2A.

PoW taking place: math problem-solving moment of the week

"Eighty percent of the submitters used this method. You can see examples below from Duncan A. and Isabella M. of Oyster River Middle School, Emily P. from Mesa Union Junior High, Nicole L. from Medina City School District, and Carson S., Will D., and Bodie S. from Hanover Street School. Many of the students at Hanover Street School mentioned in their submissions that their whole 4th grade is going to a fish hatchery soon. Maybe they will send us some pictures!"
- Annie, commenting on the FunPoW's Latest Solution

Proof School Dean's Math Textbook Now Free


The Dean of Mathematical Sciences at Proof School has made his textbook available for free download.

Sam Vandervelde's Bridge to Higher Mathematics gives high school graduates the tools and techniques that they will need to succeed in upper level math courses. The 252 page-long textbook consists of seven chapters:

  • Logical Foundations
  • Set Theory
  • Proof Techniques
  • Number Theory
  • Counting and Induction
  • Relations and Functions
  • Cardinality

It features answers for all exercises, hints to all the writing problems, periodic "concept checks" and "quick queries," and "mathematical outings" designed for self-contained group activities. Download Bridge to Higher Mathematics here:


Vandervelde, who developed questions for the USA Math Olympiad, originally wrote Bridge to Higher Mathematics while an Associate Professor of Mathematics at St. Lawrence University. He now serves as the Dean of Mathematical Sciences at Proof School, an independent school "for kids who love math" first featured here two months ago, upon the release of the non-profit's preliminary draft of an academic calendar.

Now taking place: math education conversation of the day

"I am interested in hearing [from] people [who] used e-math instructions lessons last year for Common Core Algebra. We are considering using it for Algebra II next year."
- Richard, posted to the secondary (grades 9-12) discussion group of the Association of Math Teachers of New York State

Meet the Author of Enlightening Symbols


How did mathematical notations evolve to what we know today?

Join the author of Enlightening Symbols online Wednesday, 5 November, to listen to a short presentation on the subject, pose him questions, and chat with like-minded people in the virtual audience. Freely register here:


Subtitled "A Short History of Mathematical Notation and its Hidden Powers," this most recent book of Mazur's was published by Princeton University Press earlier this year. Other works by the Professor Emeritus of mathematics at Marlboro College and Guggenheim Fellow include Euclid in the Rainforest: Discovering Universal Truth in Mathematics; The Motion Paradox: The 2,500-Year Old Puzzle Behind All the Mysteries of Time and Space; and What's Luck Got To Do With It?

Next week's free virtual gathering is part of a series from Math Future. This international network has organized more than a hundred live online events on math education in the past five years:
