St. Mary Catholic Schools Teachers

Marilyn Peterson


My name is Marilyn Peterson.  I am a math teacher at St. Mary Catholic. I attended Eastern Illinois University and graduated with a major in mathematics and a minor in physics. I have taught since 1983 and I began at SMC in the fall of 2007.  I am married and have three children, one boy and twin daughters all in college, the twins starting this fall.  In my spare time I love to read and cook.   I teach Honors Geometry, Advanced Math, Pre-Calculus, Trigonometry, Calculus A and B, AP Calculus AB, and AP Calculus BC. I am an advisor for the Math team, National Honor Society and a co-advisor for Student Council.  I also have implemented practice sessions for ACT for the students at SMC.  I think SMC is a wonderful place for both students and staff.  For students the smaller class sizes allow you to work closely with your classmates as well as teacher.  Also there are many opportunities to participate in a variety of activities.   For staff the closeness I feel with my students and coworkers really makes a family atmosphere.


      My philosophy on education is very simple.  I want to challenge students and watch them grow to their full potential. I want to take students at different levels and see them develop together for the betterment of each individual.  I want to teach students in a way that has some straightforward instruction but that also gives students room to grow and expand on their own learning.  In other words, it is not just about learning math it is much more about life lessons.  I also feel that as an educator, it is important not only to help the students that you are teaching, but also give them direction to help others. Participating in community service projects allows you to connect more with the community outside of SMC.   I also enjoy my students and everything they have to offer. I want students to know that even when there is a struggle there is always a way to fix the problem.  Everybody can learn, sometimes you have to work harder at a concept.  It is not about what you don’t know, it is about what you are going to do when you have a problem.  No matter what, you have the power to make change.
