Because there are two legs on each side! At a Math Club, we were working with paper punches and folding. Symmetry of all sorts was on everybody’s minds. A. (4) drew a unicorn with two legs. We all started to ask about it, and she said: “It has two legs on this side and two [...]

This is a sketch for an Early Algebra activity from Math Clubs. Kids can draw their own family trees, use photographs, or clipart of their favorite characters. Once the tree is built, it can be used for several activities. Start from common words, gradually moving to mathematical terms: How many grandparents are there? (point to [...]

Here is a partial list of educational practices that are quite widespread, accepted and well developed: (by CommLab ) – Rapid prototyping of everything, short cycles of [...]

Here are some ways I use Twitter for education: 1. Hashtag aggregation for topical conversations at online events, conferences and so on 2. A way to communicate about face-to-face events as they go on, with other attendees, without breaking up the oral presentations flow 3.

This parking meter is a contribution to What Can You Do With This, or WCYDWT, project. Dor Abrahamson sent it to me, together with this story for WCYDWT people: “I’m co-teaching w/ Prof. Alan Schoenfeld an undergraduate course for future teachers, at UC Berkeley. It’s a problem-solving based course, and the problems are often based [...]
Natural Math: the culture shift
May 15, 2009 - 10:01 am
Posted in Make your math, Social Math, The Now | No comments
In an overview of the Natural Math project, an audience member asked why we are doing such diverse things. Why work, all at once, on mathematical art, programming-based math, algebra for toddlers, meta-cognition and quite a few other directions we pursue at the same time? These are necessary tools for a gradual, gentle cultural change [...]
