I was happy to hear a few people liked the idea and wanted more details. I want to keep things simple so here’s what I propose. For now, I’ll suggest a book and then post about it a month later where we … Continue reading MindYourDecisions Book Club Announcement.

I can't really pick one thing that I love most. <br />I absolutely love my students. Even when I think I have a challenging group or student, I am able to separate the student and the behavior. I also love when I can see […]On This Day in Math - August 5http://www.mathblogging.org/post/1258862015-08-04T19:00:00-04:00Pat Ballew<br /><br />Mathematics is like checkers in being suitable for the young,<br />not too difficult, amusing, and without peril to the state. ~Plato<br /><br /><br />This is the 217th day of the year; 217 is both the sum of two positive cubes and the difference of two positive consecutive cubes in exactly one way: 217 = 63 + 13 = 93 − 83. (How frequently would the difference of two consecutive cubes also be expressible as the sum of two cubes?)<br /><br />217 is a palindrome in base six, (1001) and in base 12, (161).<br /><br /><br />EVENTS1638 One of […]What’s in a browser language default?http://www.mathblogging.org/post/1258802015-08-04T18:52:00-04:00Thomas LumleyOk, so this is from Saturday and I hadn’t seen it until this morning, so perhaps it should just be left in obscurity, but: Claims foreign buyers are increasingly snapping up Auckland houses have been further debunked, with data indicating only a fraction of visitors to a popular real estate website are Asian.

For the first assignment I asked everyone to write their mathematical autobiography, detailing experiences that they had, both good and bad, in the past. I also wanted to hear about any teachers who made an impression on them, favorable or unfavorable, and what other subjects they were

Instead of lecturing, I gave my students puzzles and questions to explore together in small groups. What happened over the rest of that semester turned out to be the most astonishing, uplifting experience I’ve ever had as a teacher.art bruthttp://www.mathblogging.org/post/1258772015-08-04T18:15:40-04:00xi'anFiled under: pictures, Travel Tagged: 3460, advertising, métro, Paris, pipe, RER B, Saint-MichelCall for nominations: Prize in Game Theory and Computer Sciencehttp://www.mathblogging.org/post/1258742015-08-04T17:47:31-04:00Jason HartlineFrom Rakesh Vohra: The Prize in Game Theory and Computer Science of the Game Theory Society in Honour of Ehud Kalai was established in 2008 by a donation from Yoav Shoham in recognition of Ehud Kalai’s role in promoting the connection of the two research areas.

Create and share a notecard for your desk as a reminder.<br />My reminder this year is to "have fun!" I love teaching, I love teaching math, and I love kids of all ages! I also have a tendency to get very task-oriented, focused, and forget to laugh. It's not because I'm not enjoying my work ... I am! Doing the math, teaching students ... that's fun for me! And my students comment on my passion for math. But they

I’m learning less and less about it each year so I’m hopping onto a different track for awhile, moving onto other questions. First, I wanted to collect these links in one location: Print Missing the Promise of Mathematical Modeling.

Dick, semplicemente si illudono di avere un qualche potere per poter influenzare le vite degli altri e quindi anche la loro stessa. Storia e politica di una

Only marking the final answer doesn’t necessarily provide an understanding of the student’s capabilities, and it penalizes students that make a small mistake in part of their solution.
