In February, 2025, I moved to Eastern Canada to become the Director of Nova Scotia Math Circles at Dalhousie University. What a beautiful place!
Thank you to our corporate sponsor, Eastlink, for making this dream position possible.
A talented group of young people is working for Nova Scotia Math Circles: Aaron Yip, Anh Tran, Bram Ogus, Cian Comighod, Danella Calina, Daniel Teixeira, Fatemeh Tofighi Khelejan, Hassan Mahmood, Jeremiah Hockaday, Leila Mohammadi Valehzaghard, Linh Dinh, Margo Paris, Marzieh Palizdar, Rory Whalen-Edwards, Sahil Talwar, and Timothy Power. What joyous mathematics we will be spreading! š
Let’s do an online puzzling experience, or have us visit your Nova Scotian school. Email us at mathcircles@dal.ca and let’s get puzzling together! š
MathPickle provides me with a justification for not doing my Maths homework while still learning about Maths.
I stumbled upon your site, MathPickle.com, this morning and two hours later Iām still there. Ā Just wanted to drop you a brief note to say thank you for all the great resources, ideas, and inspiring videos! Ā I canāt wait to use some these materials this Fall with my elementary mathematics methods students as well as try the unsolved problems with my two children.
The Infinite Pickle should be in every math teacherās back pocket.
The Infinite Pickle does what Martin Gardner did, but widening the door to include much younger learners.
A puzzle collection of infinite delight!

I just wanted to thank you for having our guest speaker last night.Ā I came home so excited! Ā I have always hated math, thought I wasnāt good or smart at it and that I didnāt āget itā. Ā I cried my way through 12 years of math when I was younger. Ā Something clicked last night, as if something in my brain was awakened. Ā I not only believe that math can be fun and that I have it in me to excel, but I now believe that I will be capable to teach it to my future students. So thank you very much!
PS. Please share my appreciation with Gord!
It is impossible to be a great math teacher without teaching great mathematics.
A quality math education celebrates problem-solving and tenacity-building more than arithmetic.
