Unfair Thrones - subtracting fractions ($100 classroom challenge)
This is a great way to get your students enthusiastic about subtracting fractions and optionally turning the result into decimals. The set-up is engaging for a wide spectrum of student ability. Struggling students learn how to subtract fractions while top students are engaged in tough problem solving.
This was my first puzzle to get into the New York Times.

Teaching style
All students, especially the top ones, should experience failure every day. Doing this in a light-hearted way helps remove the stigma of failure from the classroom. I fail in front of my students regularly. It's okay. I get over it. So will they ;-)
Awards & shining teacher moments
No honors or awards yet for MathPickle, but the uplifting testimonials and emails from educators make up for the lack of official recognition. Here is a sample:
"Hi Gordon, I stumbled upon your site, MathPickle.com, this morning and two hours later I'm still there. Just wanted to drop you a brief note to say thank you for all the great resources, ideas, and inspiring videos! I can't 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. Thank you, Amy Tanner (Assistant Professor, Education Department, St. Catherine University)"
