Amarillo Independent School District follows the Texas Essential Knowledge and Skills (TEKS). All of AISD curriculum and documents and resources are aligned to the TEKS. The State of Texas State Board of Education has defined the focal points for Algebra I in mathematics in the first paragraph of the introduction to the Texas Essential Knowledge and Skills. Foundation concepts for high school mathematics. As presented in Grades K-8, the basic understandings of number, operation, and quantitative reasoning; patterns, relationships, and algebraic thinking; geometry; measurement; and probability and statistics are essential foundations for all work in high school mathematics. Students will continue to build on this foundation as they expand their understanding through other mathematical experiences Unit 1 Functions and Expressions Using Functions / Solving Linear Equations / Inequalities Unit 2 Linear Patterns Unit 3 Linear Functions Unit 4 Investigating Real World Situations / Scatterplots Unit 5 Systems of Equations Unit 6 Investigating and Solving Quadratics Unit 7 Simplifying Polynomials Unit 8 Exploring Non-Linear Functions Page 1 of 6

To ensure that every student has an opportunity to learn, understand and demonstrate the Texas Essential Knowledge and Skills. Amarillo Independent has adopted the following protocols for teachers, curriculum and others to use in reference to Curriculum, Instruction and Assessment. Curriculum 1) Prioritize essential learning based on AISD written curriculum and adhere to the scope and sequence. 2) Develop deep understandings of the AISD written curriculum with an emphasis on the essential learning outcomes. 3) Create relevant learning environments in every classroom using the AISD written curriculum. 4) Analyze vertical and horizontal alignment to ensure grade level curriculum is being taught. Instruction 1) Common lessons are developed based on strategically selected grade level TEKS and include learning opportunities for students that: are at the expected level of thinking and rigor utilize research based instructional strategies are actively engaging have real world applications 2) Collaboratively align instruction to assessment. 3) Individual student instructional needs are considered and addressed in the lessons. 4) Strategic re-teaching when students do not understand. 5) Common lessons are analyzed and strengthened through a continuous improvement process such as the Professional Teaching Model, Lesson Study or other method for collaborative study and sharing. Assessment 1) Collaboratively align all assessment to the AISD written curriculum and reflect appropriate rigor. 2) Collaboratively engage in purposeful dialogue about assessment tied to clearly defined essential learning outcomes. 3) Continuously improve and adjust instruction based on common assessment results and student work. 4) Provide feedback to the annual curriculum feedback and revision process.
