Meet the Math Forum Staff: NCSM Booth 411, NCTM Booth 440


Come meet the people behind the Math Forum at the annual conference of the National Council of Supervisors of Mathematics (NCSM) or the annual meeting of the National Council of Teachers of Mathematics (NCTM).

Tell us what you think about our Wednesday (NCSM) or Thursday (NCTM) afternoon Ignite talks, and enter our drawings for chances to win

  • autographed copies of Powerful Problem Solving
  • Problems of the Week (PoW) Memberships
  • opportunities to participate in online professional development courses such as "Developing Powerful Problem Solvers"
  • subscriptions to CueThink

See you in Boston!

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

"It really helped me when I drew my picture on graph paper. One of my hallways is tiled. My kitchen is also tiled. Even my downstairs bathroom is tiled!"
- Isaac, highlighted in the Latest FunPoW

MTBoS Directory and Search


A new directory of math teachers has come online.

Filter, search, map, or browse through hundreds of the teachers in the mathtwitterblogosphere (MTBoS). To join, click the big red "Add Entry" button.

High school teacher Jed Butler's directory features pull-down menus to identify people by their interests, roles, and geographic regions. Slider bars narrow down the years when someone first started teaching, tweeting, or blogging.

The MTBoS now also enjoys its own search engine, thanks to educational technology coach John Stevens. His custom searcher combs through just the blogs of math teachers:


Looking for some inspiration? Hit the "Feeling Mathematically Lucky?" button to get a random post from the MTBoS.

Stevens welcomes other bloggers to his list, which already spans nearly a hundred sources. Simply e-mail him at stevens009@gmail.com or tweet @jstevens009.

Mathematical Cognition and Learning


Elsevier has started publishing a five-part book series subtitled "From Evolution to Remedial Intervention" — and a sample chapter has just become available for free download.

"Evolutionary and Developmental Continuities in Numerical Cognition" examines the ability to represent and manipulate numerical quantities using mental magnitudes alone — no symbols — an ability found in rats and ring-tailed lemurs; in newborn human infants and a Brazilian indigenous group whose lexicon of numbers contains words for one through five only. After surveying the research into this ability and several adaptive educational software programs that aim to boost it, the chapter discusses the relationship between nonsymbolic numerical competence and symbolic mathematics performance — and the implications that this relationship has for mathematics education.

Download a PDF of "Evolutionary and Developmental Continuities in Numerical Cognition" here:


A lead author of the book, entitled Evolutionary Origins and Early Development of Number Processing, recently posted a discount code for purchases of its print and digital formats. Save 30% by entering "STC215" when checking your shopping cart out of the Elsevier Store.
