In his book Mastery, George Leonard has some interesting thoughts about slow learners. My experience as an instructor has shown me, for one thing, that the most talented students don't necessarily make the best martial artists. Sometimes, strangely enough, those with exceptional talent have trouble staying on the path of mastery. In 1987, my colleagues at Esquire and I conducted a series of interviews with athletes known as masters of their sports, which tended to confirm this

3:48 PM | #July2014Challenge: Guess my graph

Can you guess my graph?I have done this activity with countless students over the years, in all classes from Algebra 1 to Calculus AB. I'll admit that it goes better when there is candy involved, but even without the candy engagement is high. Students need to have a graphing calculator for this activity (Desmos or Geogebra are also fine). I show them a graph using either my graphing calculator under the document camera, or a premade powerpoint with images from Geogebra/Desmos. […]

Awesome session Mary and Alex! Thank you. Thank you. Thank you. The session focused on their experiences with Grade 10 Applied students ( Canada). The entire course is activity based which allows students to not miss out on big ideas as they would in a traditional unit by unit aligned course. Students have repeated opportunities […]

tl;dr: Here is my #GTASYD Application Video!!!Full version: So I finally submitted an application to #GTASYD. Last time around on the #GTASYD I got hung up on perfecting my video using scripting and wasn't happy with the result and never submitted it. Then I submitted for GTAMTV and GTAATL this year and was not accepted for what I believe was a bad video.This time I was determined to plan ahead and spend enough time to produce a video I was happy with. I wanted to create a video using only

Here is another installment in my series reviewing the NY State Regents exams in mathematics. The following question appeared on the June, 2014 Algebra 2 / Trig exam. To start, steeper is not a well-defined term, not in an Algebra 2 / Trig class, anyway. I’m not against using the word in everyday mathematics conversations, but I’m not […]

12:52 PM | Concentric Circles Puzzle

This morning I happened across this tweet from David Marain (@dmarain) As you may know, I have a penchant for puzzles, and find it hard to leave them unsolved, so I thought about it and came up with an answer. I thought I would jot down my thought process here. For those who can’t see […]

In Kentucky, we have Program Reviews for Arts/Humanities, Writing a nd Practical Living / Career Studies (PLCS).

5:06 AM | we all crave the real stuff

I’m gonna let a couple of other people say the things I’ve been thinking about. “Learning how to be present with the big, scary openness of not-knowing is no small thing. That is why we zone out, check our phones a hundred times an hour, play video games, watch TV, assault-eat, numb out, zone out, distract […]

4:06 AM | San Diego Conversions

I was in San Diego, California the past few days doing the whole San Diego Zoo and SeaWorld thing with the family. We had a great time, but that's not the point of the post. There were definitely a handful of opportunities to capture some math moments, but I've found it more important to contain myself (mathematically) when I'm with family and make the most of our time together. Here are the two things I captured and want to share.Number 1: We were waiting to board the Wild Arctic Ride […]
