In nearly four decades of working as an accomplished math teacher and administrator, Mark authored numerous test preparation and problem solving books, guided the professional development of other teachers, and advised many schools on curriculum. And he tops that off with the self-description, “half comedian, half educator,” as he believes humor helps both children and adults learn. Mark assisted in implementing and teaching our SAT prep program at schools, and he is advising More Than Scores And Tests on math professional development for school teachers.

Read Mark’s advice (from our April 2017 blog) for the teachers in all of us.
