1 Dear Student: Congratulations on being placed in the GSE Accelerated Analytic Geometry B/Advanced Algebra class for the 0-09 school year! This is a fast-paced and rigorous college-preparatory math course that includes substantial work with the skills and concepts presented in each lesson. The course emphasizes more complex applications and challenging exercises than students might be exposed to in the traditional high school Geometry and Advanced Algebra courses. You will be required to think, to apply what you know in new and different situations, and to use problem-solving skills. The course is one in which the concepts from the beginning lessons build upon one another and are essential to the mastery of the material that will be encountered later in the semester. In order to be successful, you must have strong foundational math skills and be consistent with your homework and study habits. It is our hope that you will not only learn the major concepts of this course but that you will also become more independent in your learning and study habits, skills that you will need to be successful in future honorslevel and AP courses. It is your responsibility to be the best student you can be! Because of the pace of our curriculum, we will not be able to spend time in class reviewing skills that were presented in the pre-requisite courses. This packet represents a brief review of some of those topics that will be an important foundation for this course. This assignment will not be graded. You are responsible for this material. A basic skills test will be given the first week of school. Prerequisite Skills Basic math skills (order of operation, fractions, decimals, percent) Linear functions and their characteristics,write and graph the function Linear equations Shape, domain, range, equation and characteristics of parent functions Operations with polynomial expressions Factoring polynomial expressions Properties of exponents Geometry of circles (properties and theorems) Similarity and Congruency Area, Surface Area and Volume of plain figures and solids If you have any difficulties with this assignment, please find additional problems for practice and mastery.
