HS Math Pathways

The following course pathways can be used as a guide for planning out your/your child's math courses throughout HHHS.  Graduation requirements for all students who are proficient include earning four credits in the mathematics curriculum. Students are also required to take a minimum of three mathematics courses during their freshman and sophomore years.

For full course descriptions, course pre-requisites, and graduation requirements, please see the HHHS Course Selection Guide (available on the student information page).

Math Pathways

Additional recommendations for course selection from the Math Department:

  • As a College Prep student it is recommended that you schedule a minimum of one math class per year.

  • As an Honors student, unless you plan on taking Multi-Variable Calculus, it is recommended that you take Honors Precalculus as a Junior.

  • In addition to AP Statistics, an alternative elective is Honors to Intro to Engineering (pre-requisite is completion of Honors Alg II or an "A" in CP Alg II).
