Unfair Thrones - subtracting fractions ($100 classroom challenge)

Created by

MathPickle

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.

Venus Flytrap - Dangerous Decimal Game

Created by

MathPickle

This game gives students practice ordering decimals between 3.88 and 4.22. Which is larger 4.09 or 4.2 ? Which is larger 4.0 or 3.99 ? Top students are engaged because the game is interesting and requires tough problem solving - other students get curricular practice where they need it.

Experience

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)"
