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 Geometry.  I post announcements and assignments to our Google classrooms.

Please feel free to reach out to me by email, mdennison@mcpsmt.org.  Thank you.  Here's to the new school year!  Take care.
