# Oh, the Fractions You’ll See!

A quick quiz: How many fractions are there? This may sound like an absurd question, but in the context of elementary mathematics curricula, it makes a lot of sense. Think about it: Children encounter fractions like 1/2, 3/4, and 2/6 all the time, but do they ever see 1/100, 31/90, or 499/500? Unlikely. No brave soul … Continue Reading ››

# Resources en Español

At the recent NCTM regional conference in Albuquerque, a local teacher stopped by the booth to ask about new features of Sketchpad 5. He then shared with me his website of video lessons for Spanish-speaking students, LaracosMath.com. Some of these Continue Reading ››

# Occupy Wall Street and Quantitative Reasoning

After last week's regional NCTM conference in Atlantic City, I decided to visit New York City for the weekend before flying back home to the west coast. I love that city and, as usual, had an exceedingly good time. On Sunday, I decided to visit Occupy Wall Street, both out of curiosity and support. From what … Continue Reading ››

# Without Motivation, Standards and Assessment Are Worthless

I think all of us who have ventured into a high school classroom have faced the challenge of working with students who, for whatever reasons, are not motivated in class.  There are some reasons for this that go well beyond the scope of a math teacher's relationship with a student.  That said, the common approach … Continue Reading ››

# Those who can, teach. Those who can’t, make education policy.

2010 was a tough year. It was for me, and for many people throughout the country. But when I talk to my teacher friends, I realize how lucky I am to be out of the classroom. I'm not alone. More and more longtime teachers have had enough of being devalued and demonized. Teaching is an incredibly … Continue Reading ››

# Tick Tock: Learning to Tell Time in the Digital Age

A few years ago I was out walking in a park, and I stopped a teenager, about 16 years old, to ask what time it was. He stared at his analog wristwatch intently for a few seconds, as if he were trying to solve a problem. Then he took a cell phone out of his … Continue Reading ››

# Walk Like a Mathematician

Over the weekend, I attended the CMC-North conference at the Asilomar conference grounds. It's my favorite math teacher event of the year. When I was a teacher, the combination of the beautiful, … Continue Reading ››

# Mathematics > Computation

I enjoy browsing the TED video collection, which includes a series of talks by “thinkers and doers” in the areas of technology, entertainment, and design (hence the acronym “TED”). Similar to the five-minute Ignite talks that Key Curriculum Press hosts at various math conferences, TED presentations challenge their speakers to give the “talk … Continue Reading ››

# Thanks for All the Residue!

At this year's CMC-South conference, Dan Teague gave a thought-provoking presentation about "The Residue of Mathematics," which he defines as "what students take with them from class into their futures." Watching Dan's presentation prompted a few thoughts: 1) Wow, I really wish I could take a math course from Dan Teague! 2) What is the residue from the … Continue Reading ››
