Lyman Memorial High School Pre-Calculus Prerequisite Packet Name:
Dear Pre-Calculus Students, Within this packet you will find mathematical concepts and skills covered in Algebra I, II and Geometry. These concepts need to be reviewed and practiced throughout the summer. The completion of this review packet is very important and essential for your success in Pre-Calculus. These skills are used frequently throughout this course. Honors Pre-Calculus is a rigorous and fast-paced course. There will be extensive use of graphing calculators which is required for this course. A TI-84 Plus graphing calculator is recommended. Any other type of graphing calculator will have to be approved by the teacher. For this prerequisite packet, calculators should be used only to check work. The Pre-Calculus prerequisite packet is due the first day of school. It will be graded and it will count as a test grade. Work must be shown to support all answers. Your test grade will reflect both, your effort (50%) which is based on attempting all problems and showing work for all problems, and accuracy (50%). The packet is broken into specific concepts. Some sections have worked out examples followed by problems for you to complete. Be sure to complete each numbered exercise included in this packet. Below are a few websites you may wish to visit for additional examples and support.

Have a nice summer, Lyman Math Department
