Mathematics
The mathematics program at Greyhills Academy High School (GAHS) is aligned to the Common Core State Standards (CCSS). A student earns four mathematics credits to satisfy graduation requirements. To assess academic growth, each student is assessed three times a year using the Northwest Evaluation Association (NWEA). This assessment is used to ensure that student’s academic needs are met.
It is the goal of the mathematics department to provide all students access to an analytical and cultural curriculum aligned to the CCSS and Diné Culture Standards (DCS), and to provide additional opportunities for students who wish to excel in mathematics.
GAHS strives to align all instruction to include Dine language, history, and culture standards that will encourage Diné language, cultural values, and teachings in the daily academic courses and daily routines of students. These opportunities are to solidify the self-identity of students as they prepare to enter the workplace, vocational education, community college, and/or a university.
The mathematics program also aims to increase annual reading and writing fluency and growth, engage all students with relevant and productive instruction for life-long learners, and provide incorporation of Arizona state, Navajo Nation, National, and local standards. It is a goal to develop critical thinkers and problem solvers for societal and global issues.
Algebra
Algebra I and Algebra II are offered with the introduction of algebra concepts that focus on Common Core State Standards in the topics of: Seeing Structure in Expressions, Arithmetic with Polynomials & Rational Expressions, Creating Equations, and Reasoning with Equations. After the algebraic foundation skills are mastered, students will begin to be introduced to word problems that relate to real-world situations.

- Algebra I/ II Faculty – Ms. M. Sloan
Geometry
Geometry is offered to students who have mastered algebra concepts and are prepared to apply algebraic concepts to Congruence, Similarity, Right Triangles, &Trigonometry, Circles, Expressing Geometric Properties with Equations, Geometric Measurement & Dimension, and Modeling with Geometry standards in Interpreting Functions, Building Functions, Linear, Quadratic, & Exponential Models, and Trigonometric Functions, including Statistics & Probability.
