What does mathematical reasoning look like? How do we listen for a convincing argument? As a middle school teacher in New Jersey, I am immersed daily in the development of my students' mathematical ideas.
I began my forty-year career in education as a middle school math teacher. When I briefly took time to stay home and raise my children, I co-authored two math workbooks for McGraw Hill and taught developmental math and math education courses to undergraduate and graduate students at Rutgers University.
