Klingon Attack gives students practice factoring as they try to save the earth from Klingons. The puzzle is deep so the addition of the Klingon story-line is not the only thing that will engage children. I'll offer $100 for an example of the problem in the classroom. Submissions to gord@mathpickle.com should be photographs or stories. The best will be added to this pdf file so that other classrooms can enjoy. All photographs with people must have appropriate consent. The winning classroo

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)"
