1 Monroe Township High School Monroe Township, New Jersey Geometry *SUMMER PREPARATION PACKET* Geometry is a fast- paced, rigorous course that will provide you with the fundamental tools of geometric understanding that will support you in all future advanced mathematics courses. Since you will be taking geometry after successful completion of Algebra I, the Geometry Preparation Packet contains review material of the algebraic concepts, skills, and procedures that should be mastered BEFORE entering Geometry in the fall. Essentially, this packet provides a review of the major algebra topics as well as a preview of geometric topics. The sections are based on the Achieve ADP Algebra I End- of- Course Exam Content Standards and the Common Core State Standards (CCSS). The textbooks, McDougal Littell Algebra I (2004) and Glencoe Geometry (2005) are available online and additional support material is available on the Monroe website. Both textbook links are provided below: o USERNAME: GEOM05 *PASSWORD: N6despeZ Alternate online resources are available at: Math.html mthsgeometry The Monroe Township library also has copies of the algebra and geometry materials used in our courses. This practice problem packet is the only formal review of the concepts, procedures, and skills that you will have before beginning your geometry course. Your teacher will expect you to have mastered all topics included here. This collection of problems will identify those concepts that you have mastered as well as those you will need to practice and review. You are expected to seek extra help immediately on those concepts with which you have not demonstrated proficiency. Be resourceful use the online resources provided on the webpage! You are expected to seek extra help immediately on those concepts with which you have not demonstrated proficiency. Be resourceful use the online resources! Problems here are very representative of the types of items you will need to have mastered BEFORE geometry so we strongly encourage that you include it in your summer festivities! Good luck and enjoy! J Page 1

About how far does Michael run? m Julia wants to paint two rectangular walls of her bedroom. One bedroom wall is 15 feet long and 8 feet high. The other wall is 12 feet long and 8 feet high. She wants to put two coats of paint on the walls. She knows 1 gallon of paint will cover about 350 square feet of a wall. Will one gallon of paint be enough? Show all of your work and explain your answer below. Page 9
