Ms. Margie Dennison
Greetings mathematicians! My name is Margie Dennison and I am so happy to be a mathematics teacher at Sentinel High School.
This year, I am teaching Algebra 1 and Algebra 1A. Algebra is the backbone of all the math you'll experience as you move forward in school and in life. It is so cool, and I look forward to diving into it with all of you.
