1 Mathematics Prince George s County Public Schools Course Code: , , Prerequisites: Algebra 1 Credits: 1.0 Math, Merit Geometry provides students with the skills outlined in the Maryland Core Learning Goals for Geometry. These skills include using logic to develop arguments, working with the postulates and theorems of Euclidian geometry, applying rules for parallel and perpendicular lines, identifying congruent and similar figures, classifying polygons, measuring angles and segments, writing proofs of triangle congruence, drawing, constructing, and performing plane transformations. INTRODUCTION: Typically ina Math class, to understand the majority of the information it is necessary to continuously practice your skills. This requires a tremendous amount of effort on the student s part, Each student should expect to dedicate approximately 1 hour of studying for every hour in class. Some hints for success in a Math class include: attending class daily, asking questions in class, and thoroughly completing all the homework problems with detailed solutions as soon as possible after each class session. INSTRUCTOR INFORMATION: Name: Ms. P, Johnston patric.johnston@pgcps.org Planning: A-Day Mod 4 (1:23 PM -2:30 PM), B-Day Mod 3 (12:10 PM - I:20 PM) Phone: (301) ext. 280 CLASS INFORMATION: COURSE NUMBER: CLASS MEETS: Every other day for 85 minutes ROOM: 315 TEXT: Geometry, Prentice Hall WEB SITE: CALCU LATORS The use of a calculator is required, While participants may use any graphing calculator, the instruction in the course requires the use of scientific calculator with trigonometric functions. Knowledge and competence for use of graphing calculators will be the sole responsibility of the student.

2 GRADING: Your grade will be computed from the following categories: class work, homework, and assessment. The following weighted average will be used to calculate your grade, ~ategory ~ri-efl)esc riptfo~ CLASS WORK/ ] HIS INCLUDES ALL WORK COMPLETED IN THE CLASSROOM SETTING.

The curriculum is embedded with standardized test preparation activities and test-taking strategies that will help students be successful on high-stakes tests like the SAT, ACT or college entrance exams. The practice in each lesson will prepare the students for the format as well as for the content.
