Math Department


Welcome from the Horizon High School Mathematics Department!

In the 21st century, a vibrant democracy depends on the full, informed participation of all people. We have a vast and rapidly growing trove of information available at any moment. However, being informed means, in part, using one’s sense of number, shape, data and symbols to organize, interpret, make and assess the validity of claims about quantitative information. In short, informed members of society know and do mathematics.

Mathematics is indispensable for understanding our world. In addition to providing the tools of arithmetic, algebra, geometry and statistics, it offers a way of thinking about patterns and relationships of quantity and space and the connections among them. Mathematical reasoning allows us to devise and evaluate methods for solving problems, make and test conjectures about properties and relationships, and model the world around us.

Calculator Reminder!

All students enrolled in a Mathematics course MUST have a TI-83+ or TI-84+ graphing calculator. These can be purchased at a variety of stores and online. We also have calculators students can rent for $20/school year. You can either rent one at the bookkeeping office or at Just show the teacher the receipt and they'll check it out to you.

Philosophy on Homework

We believe that homework supports and enhances student learning by allowing students to practice skills, deepen understanding and become more confident in their mathematical ability.  The Contemporary Mathematics teachers will assign meaningful homework problems two or three days a week that students can complete in a (weekly) total of 30-40 minutes.  We will ensure students understand the concepts  and have the necessary skills to successfully complete these assignments before assigning them as homework.  We will provide timely feedback on student homework, with time allotted in class and/or outside of class, for student clarification.  Homework is an assessment of developing knowledge and understanding, and hence will be scored in the "formative assessment" category of the gradebook.

Homework Help and the Math Help Center

Horizon math teachers provide homework help and supervise test re-takes and corrections in the Math Center. Three days a week, for as many periods as possible, there is a math teacher in mobile 2 to assist students. There is a schedule under Documents below.
