Mathematics and Computer Science



The goal of the Harrison Central School District K-12 math curriculum is to develop independent problem solvers (flexible and resourceful) who appreciate mathematics and its purpose in their everyday lives.  To achieve this goal, the curriculum is accessible to all students; it is mathematically rich, providing students opportunities to engage in hypothesizing, conjecturing, predicting, and verifying.  The curriculum is built on the following tenets:

  • High expectations and strong support for all students
  • Balanced approach between conceptual understanding and procedural fluency
  • Coherent, well articulated, and aligned to Common Core State Standards



The progression of concepts and skills developed through the elementary grades (K-5) is aligned to the Common Core State Standards.  In grades K-2, the major focus is on number, place value, operations (addition and subtraction), and properties (communicative and associative).  Geometry, Measurement, and Data play supporting roles in the development of number concepts and relationships in K-2. In grade 3, the focus shifts from addition and subtraction to concepts of multiplication and division, with an understanding of the distributive and associative properties.  In grades 4-5, students become fluent with multiplication and division concepts and procedures.In grades 3-5, there is a major emphasis on fraction understandings, progressing from conceptual (grade 3) to fluency with operations (addition, subtraction, multiplication and division), which culminates in grade 5. As in K-2, Measurement, Geometry, and Data play supporting roles in the development fractions.

Grade K: Counting Skills and Early Addition and Subtraction
Grade 1: Addition and Subtraction within 20
Grade 2: Addition and subtraction within 1000
Grade 3: Relationship between multiplication and division
Grade 4: Multiplication/Division/Fractions
Grade 5: Fractions and Decimals

Required Assessments:
NYS Common Core Mathematics Exams Grades 3,4, & 5



The 6-12 curriculum and pathway offerings are organized to ensure all students are College and Career ready, a goal of the Common Core State Standards.The middle school curriculum connects the learning students have done in the elementary grades to the formal study of Algebra, Ratios and Proportions, Geometry, and Statistics.  In grade 7, all students receive an accelerated curriculum to prepare for the Algebra I course in grade 8. 

Grade 6: The Number System, Ratio and Proportional Relationships, Algebra, Geometry
Grade 7: Rational Numbers, Proportional Relationship, Algebra, Geometry, and Statistics/Probability
Grade 8: Number Sense and Equations, Functions, Systems of Equations, Inequalities, Quadratics, Statistics

Required Assessments:
NYS Common Core Mathematics Exams Grades 6 & 7
Regents: Algebra I - Grade 8



To meet the interests and needs of all students, the Department of Mathematics and Computer Science offers a variety of courses at Harrison High School that comprise differentiated pathways with options for Regents, Non-Regents, International Baccalaureate, and Advanced Placement courses.  The unique aspect of our mathematics program allows students to merge into different pathways at different points in time as they feel comfortable with the learning materials at different levels of readiness.
