    Seattle’s high school mathematics students prepare for college, careers, and life by completing at least three core courses, with four years of mathematics being highly recommended. State graduation requirements mean that students will complete at least three years of mathematics in high school, including at least:
    Algebra I, Geometry, and Algebra II or its equivalent or IB Mathematics. 

    PreCalculus, AP Statistics, AP Calculus, and/or IB Mathematics provide additional preparation for college and careers, and provide an important transition from high school to college-level mathematics.

    Our high school mathematics program, guided by Washington State standards, provides a balance of:

    • Conceptual Understanding
    • Procedural Proficiency
    • Problem-solving and Processes

    State Mathematics Requirements for Graduation

    Starting with the class of 2013, Washington State requires that students earn AT LEAST THREE credits of math (Algebra I; Geometry; and Algebra II or a rigorous, high school‒level math course that meets the student’s education and career goals identified in the student’s high school and beyond plan). For a list of state minimum credits to graduate, please see the Washington State Board of Education.

    End of Course exams for Algebra 1 and Geometry begin in 2011. These exams are being replaced by the state graduation exam.  For a list of required tests for graduation, please see the Office of the Superintendent of Public Instruction

    Mathematics Textual Materials

    In 2009, Seattle Public Schools adopted materials published by Key Curriculum Press for Algebra I through PreCalculus, and by Pearson Learning for AP Statistics, as shown below. Each student will receive a hardback textbook for use at home and in school. The books include detailed examples, a glossary and index, and selected answers and hints.

    Each student will also receive a code from his/her teacher to access the entire textbook online. The online text has interactive features which enable students to link from pages in the book to practice problems, dynamic explorations, and calculator notes.

    Click on the textbook links below for family resources available online, or go to and click on the book cover for each course. Online resources include:

    • A Guide for Parents (in English and Spanish)—A brief summary of each chapter, includes tips for working with students, chapter summary exercises and review exercises with complete solutions.
    • Condensed Lessons (in English and Spanish)—A detailed explanation of each lesson. These can provide extra help for students who have fallen behind or missed class, as well as support for adults who want to understand the details of the mathematics.
    • More Practice Your Skills—a set of additional exercises for each lesson in the book for students who want extra practice.
    • Calculator Notes, Programs and Data—helpful information, programs and tips for using calculators for specific activities.
    • Dynamic Explorations—Structured investigations available online so students and their families can explore mathematics concepts at home
