Graham Fletcher has served in education as a classroom teacher, a math coach, and currently as a math specialist. He is continually seeking new and innovative ways to support 潑請弝けapp and teachers in their development of conceptual understanding in elementary mathematics. He is the author of Building Fact Fluency and openly shares many of his resources at gfletchy.com.
Tracy Johnston Zager is a district math coach who loves to get teachers hooked on listening to kids mathematical ideas. She is a co-author of the Building Fact Fluency toolkits and the author of Becoming the Math Teacher You Wish Youd Had: Ideas and Strategies from Vibrant Classrooms.
