The best times to contact me by phone are during 4th block (12:45 - 2:00) or between 3:00 and 3:30.   I check email frequently, and will do my best to respond within 24 hours.

Thank you for visiting my teacher webpage.  I've been teaching at CGBHS since 2014.  I teach Geometry, Advanced Math (precalculus) and Math Seminar.  I am also one of the Junior Class Advisors.   My goals are to create a positive environment for students to learn math, to teach money skills through a year long simulation called "project reality", and to prepare students with 21st century skills that will help them in their future career path.


This year I have made a change in how I assess student learning for my Geometry and Advanced Math classes.  Instead of assigning homework and scoring it, I am now giving a quick learning check after each lesson to see how well students understand each learning target.   I will still give students the opportunity to do the homework to practice, but most of the time those assignments will be optional.  Each learning check is 5 points.  If a student does poorly on a learning check, I encourage them to see me during work time in class or during Rocket Block to practice that lesson some more.  

Quizzes will be typically be between 20 and 40 points, and tests are 100 points.

The reason for the change to learning checks instead of turning in homework is two-fold.  One, it emphasizes to the student that the goal is to learn the concept, not to finish an assignment.  The 2nd is for me to measure where each student is before we take quizzes and tests.  

I allow students to retake quizzes and tests.  Students can retake each quiz one time each, and the retake quiz score will be averaged with the original.  Students get 1 test retake per semester and it will also be averaged with the original score.  For more details, look over the test and quiz retake policy in the syllabuses on each of the class pages.

If you have any questions regarding learning checks or assignments, please contact me via email, phone, or talk to me at parent-teacher conferences.
