Michael taught math for over 40 years. He was a high school math teacher for San Francisco from 1969 - 2001. Michael wrote his own curriculum to teach geometry using familiar objects like patty paper, tennis ball cans, and string. This classroom material eventually became the innovative textbook "Discovering Geometry". In addition to "Discovering Geometry", he has published "Patty Paper Geometry", the "Mathercise Series", "What’s Wrong with This Picture?", "Smart Moves" and "Pirate Math." Michael continues to serve as a master teacher and mentor to other teachers. He officially retired from teaching high school in 2001 and teaching professional development workshops with school districts and math conferences in 2017. He volunteers weekly at a San Francisco elementary school. Michael often says working with the fifth grade class is the “highlight of his week.”
I believe students learn with a greater depth of understanding when they are actively engaged in discovering concepts (inquiry learning). In today's world, the skills valued in all working environments are the ability to problem solve, express ideas, and to work as part of a team. I want my students to be engaged daily in doing mathematics and exchanging ideas in cooperative groups.
