High School

Mission Statement

The Ridgewood Public Schools Mathematics and Computer Science programs provide opportunities that encourage all students to develop a positive attitude about mathematics and computer science. By utilizing mathematics and computer science in meaningful ways to explore authentic tasks students are expected to go beyond repetition and memorization into problem solving and understanding. We believe that our students are well prepared for the future.

Period 9

In Mathematics, probably more than most other subjects, practice is important. In order to practice, a student needs to understand what is being taught.  Students are encouraged to reach out to their teachers if they feel the need for additional help.  This is the reason for Period 9 which runs every day from 2:50-3:15.  Each teacher is available during this period and they are there to help.  Please make every effort to see your teacher and take advantage of this opportunity.

Calculator Requirements

Below is a letter explaining the calculator use from Algebra I through AP Calculus.

Dear Parents,

As we plan for another year of school and make preparations for new classes, one consideration is the purchase of school supplies.  Technology has become an integral part of our lives and in the technical subjects, it has become indispensable.  We will be using technology extensively in mathematics and science classes.

One of the tools that individual students must master is the use of a calculator.  This will enable students to visualize functions and make inferences about mathematical data.  Using a calculator is a skill, which should be practiced often to make maximum use of the technology.  For this reason, we strongly recommend that students purchase their own calculator.  This will enable them to use the same calculator for all four years of high school, and it can be taken to college as well.

The mathematics department recommends the purchase of the TI-nspire for use in all high school mathematics courses.   The TI-nspire CX II is the latest version of the calculator that can be used through high school and into college.  If your child is in the honors math program, then the calculator should be the CX II CAS version.  If you want more information about this calculator, you can visit
