Course Overview

NC Math 2 Curriculum Overview
 
Students explore two new functions: inverse variation and square root. They use the functions to model contextual situations, interpret their key features, and solve problems. Students identify the effect of transformations on the graphs & tables of functions. Lastly, they extend their understanding of expressions as they work with radical expressions and rational exponents. 
 
Students extend their understanding of quadratic functions from Math 1. They rewrite quadratic expressions into vertex form by completing the square. They solve quadratic equations with real and complex solutions using quadratic formula. Students build quadratic functions using a variety of different strategies. 
 
Students analyze and compare functions. They solve one variable inequalities using different methods. Students create and solve systems of equations that include any combination of equation types: linear, quadratic, inverse variation, and square root. 
 
Students develop an understanding of proof while examining the properties of angles and parallel lines. They extend their understanding of transformations from middle grades to develop more formal definitions. Students use transformations as a foundation for establishing congruency and properties of geometric figures. 
 
Students recognize dilations produce similar figures and learn to identify and use the scale factor and center of dilation to solve problems. They establish the AA criteria for similar triangles. Students reason with similar right triangles to define the trigonometric ratios and use them to solve problems. 
 
Students use sample spaces to calculate probabilities. They develop an understanding of conditional probability and independence. Students generalize their repeated reasoning to develop probability rules and strategically use the rules to solve problems. Students compare results from simulations to theoretical probability. 


NC PreCalculus Curriculum Overview

The purpose of Precalculus is to build upon the study of algebra, functions, and trigonometry experienced in previous high school mathematics courses. This course will build on students’ algebraic skills and understanding of functions to delve into real world phenomena and to deepen understanding of the functions in the course. This course is designed for students pursuing careers in STEM-related fields. Students will be prepared for Calculus, AP Calculus and any entry-level college course.
