About Our Classrooms & Courses

The goal of teaching mathematics in the Portsmouth School District is to develop the value and enjoyment of mathematics in our students.  Our goal is for students to be able to reason and communicate mathematically, have confidence in their mathematical skills, use math to make informed decisions in their daily life, and see themselves as mathematical problem solvers. In solving problems, students will be able to question the reasonableness of a solution, be flexible, persevere, and take risks. Students will have these skills to adapt to the changing needs of the 21st Century.


  • A minimum of three credits of math is required for graduation, to include Algebra I. 
  • Progression of courses upon teacher recommendation.
  • All students should consult with teachers and counselors concerning course selection.

In addition to the course offerings in the Math Department, students are welcome and encouraged to join the Math League or other recreational math contests offered throughout the year. The Math League meets twice monthly and competes at surrounding schools eight times a year.

Additional Supports

Students may schedule into Flex Block with their assigned teacher or any other teacher in the department.   Our Math Interventionist hosts the weekly Math Support Center during Flex Block on Tuesdays and Thursdays as well; students can also schedule in with her any day of the week, Tuesday to Friday.   Our Intervention Team closely monitors student progress through student performance data, used to provide additional support for students in need.
