Christina Tondevold: “I am a former middle school math teacher who learned, and taught, math the traditional way. That was until I realized that many of my students did not learn math the same way I did. So, I embarked on a journey to increase my understanding of mathematics in order to teach it to my students. Now I am a Recovering Traditionalist and a teacher educator who gets the pleasure of helping other teachers learn what I learned about how children think about mathematics.”
