A math teacher at SPA since 1969, Bill Boulger says, "My most satisfying moments have been the result of assisting students to develop an independent understanding of mathematical concepts through an open discussion of well-chosen problems." Mr. Boulger coaches the Upper School mathematics team. He teaches 9th and 10th grade Honors Geometry. In his classroom, he says, “Discovery through exploration fosters curiosity and imagination while providing the foundation and tools for lifelong learning.” Mr. Boulger is chair of the math department, has received distinguished teaching awards from the Mathematical Association of America, and received the Presidential Scholars Teacher Recognition Award in 2006. He enjoys researching math curricula from other countries, and collects math texts from Ireland, Japan, Taiwan, Singapore, and Germany. He holds a B.A. and an M.Ed. in mathematics from St. Mary's University and serves on the board of the Minnesota High School Mathematics League. In his spare time he enjoys reading and spending time with his family.
