Mathematics The study of mathematics is a valuable asset to one's education. A required subject for seventh and eighth graders and an elective for ninth graders. General Math provides a solid foundation to which more advanced courses can be added. The first of these subjects is the freshmen elective, Algebra, which concentrates on the basic fundamentals of linear equations and elementary geometry. Plane Geometry, offered to senior high students, familiarizes them with useful axioms, postulates, and theorems. Students of the Advanced Algebra classes work with linear, quadratic, and cubic numbers and symbols to facilitate the solving of various types of equations. Lastly, Solid Geometry, the study of three dimensional figures and Trigonometry, a deeper examination of triangles, are semester units combined to form the most advanced mathematical course. Through these progressing series, students not only increase their skill in mathematics, but they also promote the use of logic and reasoning in thinking. Mr. Robert Bowman instructs the sophomores and juniors in both Plane Geometry and General Mathematics. Between his classes he wields the gavel as chairman of the sophomore advisors, and the remaining time he spends with his hobbies: golf, tennis, and chess. Studying at the University of Minnesota, Mr. Bowman attained his Bachelor of Arts and Master of Arts degrees. Mr. James Chapman, an eighth grade advisor, teaches General Mathematics. When not occupied with the problems of fractions and decimals, he takes part in extra-curricular activities. Mr. Chapman attended the University of Minnesota and has a Bachelor of Science degree. Mr. Ted Greer, doubling os a senior class and Hi-Y advisor, is the Trigonometry, Solid Geometry, and Advanced Algebra instructor. Despite this heavy schedule, every season he coaches a sport, whether it's junior varsity football, hockey, or tennis. Mr. Greer finds relaxation in sailing or playing hockey or tennis. An alumnus of the University of Michigan, he has a Bachelor of Science and a Master of Education degree. Miss Thusnelda Doering, in addition to teaching Mathematics to seventh graders, explains the equations and unknown quantities of elementary Algebra to freshmen. Advising the Junior High Red Cross Council and taking charge of the bookstore currently occupy much of her time. From the University of Minnesota, Miss Doering received her Bachelor of Science degree. Mr. J. Orval Engen, known to the entire student body as a photographer, is a seventh grade Mathematics teacher. Interested in both astronomy and geology, he studied at St. Cloud Teachers' College and Augsburg College, where he received his Bachelor of Science degree. Mr. E. W. Ironside prepared for eighth grade Mathematics instruction at St. Cloud Teachers' College where he graduated with a Bachelor of Education degree. In charge of the entire Audio-Visual Aids Department, he orders all the materials requested by various departments and makes arrangements for projection with the student staff. Mrs. Joyce Letvin's two main interests are instruction in elementary Algebra and Plane Geometry, and participation in sports. She particularly enjoys golf, tennis, and horsebackriding. Mrs. Letvin is a graduate of Hamline College, where she earned a Bachelor of Science degree. Hey, thut Ihe door! Page 25
