Here’s a break from Math. Ever feel like you’re just not good enough? You’re appreciated somewhere. Here’s a music video from Secret Agent 23 Skidoo, a musician from Asheville, NC whose friend Adam Strange is a super painter and whose art is hanging in my apartment. Ok, enough of the run-on sentences… Chin up and Enjoy!

Music is funky, I know. It was free from YouTube. My original Vivaldi remix was flagged by a very busy YouTube user! Let’s factor some trinomials! For a “how?” instead of a “why?”, see Factoring Trinomials: A Video ‘How To’ When A >1 .

Thank you for visiting my site. I hope you find it informative and that you will see the usefulness of the ZeroSum Ruler. I am currently testing the ruler’s effectiveness for my graduate thesis, and so far the results have been positive. Student quiz scores went up! In a month or so, I plan to give a delayed retention quiz that will test if student knowledge of the relationship between positive and negative integers stuck long-term. Hopefully it did, but they will always have their rulers if they still need help. I made one for every student to give out at the end of my study.
Please email me with any questions! In the meantime, below is the unedited video on how the ZeroSum Ruler works. If you like shorter videos, the green one over there in the margin is the one for you ——————————————————->

That’s Beck in the background. I hope he doesn’t mind!
