Mathagogy's Nine Newest


Mathagogy is back!

New pairings of "mathematics + pedagogy" rolled out last week organized around nine themes:

  • change and justice
  • resilience and understanding
  • video and ability
  • critique and inquiry
  • computers and thinking
  • creativity and beauty
  • practice and memory
  • grit and mindset
  • visualization and gaming

Each theme pairs a video and an article. Speakers include Sir Ken Robinson, Dan Meyer, Sal Khan, and Michael Pershan. The accompanying essays come from Jo Boaler, Paul Lockhart, Daniel Willingham, and James Gee, among other authors.

Mathagogy first appeared in these pages shortly after it came online last June. With this recent release, creator Peps Mccrea, a Senior Lecturer in the School of Education at the University of Brighton (UK), now also offers portfolio space online to compose "think-pieces" that respond to tasks for each theme.

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

"From 'Women's Walkway' I have actually learnt so many things and the most interesting thing was that Women's Walkway had a relationship with fractional parts. At first, I used the sheet that Mr. Booth printed out. However, when I got the idea of folding the walkway in half, I only had to color the 1/2, so that when I just find the number of the half, I can just do 'times two' and get the answer of the full area."
- Seeun, highlighted in the Pre-Algebra PoW's Latest Solution



What has zero volume ... infinite surface area ... and levels on four continents?


By folding up over a million business cards, volunteers from around the world have been assembling Menger sponges — fractals that resemble a cube with a square section cut through the center in each of its three directions. Successive levels of Menger sponges will come together the week of 20-26 October, in conjunction with the Martin Gardner Global Celebration of Mind (CoM) Gatherings.

Follow the fun on Twitter with the hashtag #megamenger — or join in by downloading instructions and contacting your nearest MegaMenger build site, of which the U.S. already has fifteen.

Now taking place: math education conversation of the day

"That's easily the coolest flyer I've ever had my name on. :)"

Pure Numbers Daily Blog


The Pure Numbers Daily Blog posts a new equation out of the individual numerals in the date, such as

  • 10.14.13, the last Ada Lovelace Day
            (1 + 0) * 1 * 4 = 1 + 3
            1 + 0 = 14 - 13
            10 = (1 * 4) + (1 * 3!)
  • 6.15.13, the Math Forum's 21st birthday
            6 + 1 = 5 - 1 + 3
            6 = 1 + 5 = 1 * 3!
            6 / (1 + 5) = 1^3
  • 3.14.13, the only palindromic Pi Day this century
            3! = (|1 - 4| * 1) + 3
            3 = |1 - 4| = 1 * 3
            3 - 1 + 4 = 1 * 3!

Search for past dates back to 10.11.12 — when the blog began, two years ago ... tomorrow!
