1 CURRICULUM GUIDE Algebra II College-Prep Level Revised Sept 2011 Course Description: This course builds upon the foundational concepts of Algebra I and Geometry, connects them with practical real world applications, and prepares students to meet the challenges of a higher education and practical work in the world. Students will be looking at mathematics from various vantage points as a way of learning to confront problem-solving in new ways and in new situations and will develop mathematical understanding through the solving and guided investigation of both real-world and abstract mathematical problems. Students will learn to formulate solutions to these problems as well as communicate these concepts to others in an understandable manner. The school wide learning expectation for problem solving is addressed throughout the course. Intended Audience: This course is designed to meet the needs of students who are college bound and have successfully completed Algebra I and Geometry, but whose main strength is not in mathematics. While this course contains a treatment of topics from both Algebra I and Algebra II, there is some reinforcement of basic algebraic skills and a review of concepts and methods seen before in Algebra I. Course Goals: Students will learn to Solve problems using a graphing calculator. Find solutions to linear, quadratic, exponential, logarithmic, polynomial, radical and rational equations both algebraically and graphically. Find solutions to systems of linear equations, both algebraically and graphically Analyze and formulate equation models and systems to solve real-world problems algebraically and graphically. Understand the concepts of function and relation and be able to differentiate between these as well as analyze functions algebraically and graphically to determine domain, range, x- and y-intercepts, zeros. Gain a full understanding of quadratic functions and equations including the analysis of graphs of quadratic functions and solutions of quadratic equations using both factoring and the quadratic formula. Develop an understanding of complex numbers and their relationship to the roots of quadratic functions. Gain a full understanding of exponents (positive, negative, fractional) and radicals and the relationship and conversions between these. Gain an understanding of polynomial functions, their zeros and values. Learn to operate fully (addition, subtraction, multiplication and division) with rational expressions including those involving literal expressions to be factored.

2 Essential Questions/Habits of Mind What is a reasonable answer for this problem? Do I have a reasonable estimate of expected solutions? What method should I use to solve this problem? What is the relationship between the roots of a function and its graph? What is the relationship between a problem and the equations / functions which are used to model and solve it? This course addresses the following school-wide expectation: Demonstrate problem solving and critical thinking skills Collects and evaluates information to identify patterns, make inferences, and draw conclusions Predicts results using conceptual knowledge Identifies and analyzes the possible alternative strategies to solve a problem Develops original and well-thought decisions/solutions that apply appropriate and relevant information First Quarter Course Outline Unit 1: Functions, Equations, and Graphs Relations and Functions Linear Equations Linear function, dependent and independent variables, intercepts Slope Standard form of a linear equation Writing equation given point and slope or two points Slope intercept form of a line Parallel and perpendicular lines Direct Variation Using Linear Models Absolute Value Functions and Graphs Vertical and Horizontal Shifts Two-Variable Inequalities Standards*: [AI.N.1] [AI.N.2] [A1.P.10] [A1.P.5] [10.P.10] CBL Lab: Modeling Motion with Linear Equations Graphing Calculator Absolutely activity Unit 2: Linear Systems
