Tina Cardone spent over 10 years teaching high school math at public schools in Massachusetts. In addition to her teaching experience, Tina is an author and community organizer. Active in the online math community, in 2013 she cataloged the ideas of her Twitter network and wrote the book *Nix the Tricks* (followed by a second edition in 2015). Tina has presented at regional and national conferences on a variety of topics. One of her passions is helping teachers shift mathematics instruction towards concept development and away from tricks. She also enjoys thinking about ways to make math class an enjoyable and successful experience for all students. When she isn’t writing or talking about math, Tina enjoys crocheting and hiking with her foster dogs.
