Tina Cardone is an enthusiastic, collaborative, and experienced educator whose professional interests span from K to 12 as well as from math content to equity. She began her career as a high school math teacher before transitioning to curriculum writing and providing professional learning. During her decade in the classroom she taught all levels of high school mathematics to diverse groups of students with a variety of learning needs at public schools in Massachusetts. As an active member of the online math community, in 2013 she organized the ideas of her Twitter network into the book Nix the Tricks (followed by a second edition in 2015). She has worked with districts to make a shift toward conceptual development and presented at regional and national conferences. Tina first left the classroom to write curriculum; she was the geometry lead for the Illustrative Mathematics high school curriculum. In 2019, Tina joined the Center for Mathematics Achievement at Lesley University, where she acts as assistant director, engaging in research while providing professional development and coaching to educators nationally and internationally. Across her professional ventures, Tina enjoys thinking about ways to make learning mathematics an enjoyable and successful experience for all students. When she isn’t writing or talking about math education, Tina enjoys crocheting and exploring the outdoors.
