# Mathematics

The usual course of study for a Loyola student is Algebra I, Geometry, Algebra II, Pre-Calculus, and Calculus. These courses are taught as college preparatory courses and the pace and levels of difficulty are set accordingly. For students with exceptional background and/or exceptional aptitude in math there are honors and AP options.

### Mathematics Graduation Requirements (6 semesters)

Students are required to complete six semesters of mathematics. Prior to enrollment, students will take a placement exam to determine math aptitude, and course assignment. Most students will be enrolled in an Algebra/Geometry hybrid course freshman year. Sophomore year students will complete Algebra II or Pre-Calculus, and junior year students take Pre-Calculus or Calculus. Many seniors decide to enroll in a final year of math where they complete advanced placement courses in calculus, multivariable math, or computer programming/science.

#### Mathematics Teacher Aides

**Teachers:** Emily Villa de Rey

This program is for outstanding seniors who want to encounter the learning situation from a different viewpoint. The teacher aide is responsible for assisting the teacher in the daily classroom activities by leading group discussions and helping small groups in their work, and by assisting students who require tutorial help. The generous senior is given a chance to practice concern for his fellow man. Credit is given for this course. Students wishing to apply should consult with the teacher they wish to assist and then inform the Department Chairperson of their choice. This should be done weeks before registration. Prerequisite: Students must have a 3.0 GPA overall, a 3.0 GPA in Math, and a willingness to accept the responsibility of working in the classroom every day. Permission of the instructor and department chairperson is required.
