While visiting a grade 4 classroom in 2005, I did an impromptu “nasty” thing. I challenged the students with an unsolved problem of mathematics from 1937 and asked them to solve it. I didn't tell them it was unsolved. The students became wonderfully enthralled and that experience woke me up.

Seven years and hundreds of classroom visits later, MathPickle.com shows students tackling a wide range of tough problems - the gems of mathematics that deserve to be in every curriculum. Engaging a wide spectrum of student ability is MathPickle’s mission:

Engaging the top students without losing the bottom students...

Engaging the bottom students without boring the top students.

That is inspiring.

MathPickle’s supporters are K-12 teachers - mostly based in North America, Australia and Europe. However, I have asked them not to contribute. Teachers everywhere are hard pressed financially. I want other members of society who value education to be my RocketHub supporters.

In the first weeks, several have donated generously. Kin Lo, a professor at the Sauder School of Business at the University of British Columbia was the first to fuel the MathPickle rocket. Amir Fazel, Robert Hamilton, David Wees and Maria Droujkova followed. David and Maria are both dynamos in mathematics education so their participation is a valued endorsement.
