All St. Louis U. High students are required to take three years of mathematics. The normal sequence is Algebra I, Geometry and Algebra II/Trig. Students who enter SLUH having demonstrated a knowledge of Algebra I are required to take Algebra II, Geometry and Precalculus the first three years.

Advanced courses are available in Geometry and Algebra II/Trig for students who are highly motivated in the area of mathematics and have demonstrated by their performance in previous math courses that they are talented and interested in the study of mathematics. Teacher recommendation is required for admission into these courses.

All mathematics courses in the senior year are electives. AP Statistics, Calculus BC and Calculus AB are advanced placement college credit courses taken for the entire year. Precalculus I, Senior Math Topics, Advanced Studies in Geometry, Precalculus II, and Probability & Statistics are offered for one semester only. It is the goal of the mathematics department that all teachers will incorporate as much modern technology into their courses as possible.

All students will master the use of the graphing calculator while the computer and iPad will be used for demonstration as well as a hands-on learning tool when appropriate.
