IB Math Studies SL Summer Assignment Information Welcome to Pre-Calculus! This summer review assignment is designed to refresh your Algebra 2 and Trigonometry skills. It includes information that was taught in Algebra 2 Trig and will be used daily in PreCalculus.

Assignment Requirements: You MUST show all work in order to receive credit! This includes the multiple choice problems. All work must be done on the attached answer sheets in a neat and organized manner. No work, no credit! Please show work and respond to Part 1 in the space provided. For Part II, please write your multiple choice answers on the answer sheet that has been provided in this packet. Due Date: This packet must be completed by the 1st day of school. 15 % will be deducted for each day that this packet is late. Grading: This assignment will be collected and graded based upon completion and correctness. It will count as your first test grade for Quarter 1. You will have an opportunity to ask questions during the first couple of days of school. A quiz covering the material will be given during the first week of school. These topics also tie in with the first few units of Pre-Calculus. About IB Math Studies SL: The course concentrates on mathematics that can be applied to contexts related as far as possible to other subjects being studied, to common real-world occurrences and to topics that relate to home, work and leisure situations. The course includes project work, a feature unique within this group of courses: students must produce a project, a piece of written work based on personal research, guided and supervised by the teacher. The project provides an opportunity for students to carry out a mathematical investigation in the context of another course being studied, a hobby or interest of their choice using skills learned before and during the course. This process allows students to ask their own questions about mathematics and to take responsibility for a part of their own course of studies in mathematics. A TI-84 Plus calculator is recommended and will be used by the instructor during lessons throughout the year. Be prepared for at least a half hour to an hour and a half of homework each night with weekly quizzes and/or tests. This course requires an individual project that is an extended piece of work based on personal research involving the collection, analysis and evaluation of data
