Nix The Tricks is simultaneously:
- a free eBook cataloging many of the rhymes, shortcuts, and mnemonics teachers use (I'm looking at you, FOIL) that rob students of a conceptual understanding of mathematics.
- a labor of love from editor Tina Cardone.
- a great example of the deep bench of talent we have in Math Twitter Blogosphere.
It was all sourced from math teachers online. It's all free to you.
There's something for all of us in there from elementary mathematics through Algebra.
