Name Summer Assignment for College Credit Math Courses 015-016 To: All students enrolled in Pre-AP PreCalculus and Dual Credit PreCalculus at El Campo High School College math classes utilizes skills and concepts you learned in previous math courses such as solving equations, working with algebraic expressions, and factoring. If you are unable to apply these skills, this course will be difficult. Therefore, this summer assignment is a review of previously learned concepts you need in order to be successful in college math. This assignment is due on the first day of school and will count as one daily grade. Be sure to show your work on every problem in the space provided, write neatly, and circle your final answer. In addition, you will be tested on the topics covered in this packet during the second week of school. This test will be a major grade. Before the assessment, you will have the opportunity to ask questions about the summer assignment in class. Below are website resources and a reference sheet that have full instructions on the reviewed skills in this assignment. If you are unsure how to attempt these problems, please consult the resources. If you have any questions regarding this packet, please email dhamman@ecisd.org or msandoval@ecisd.org..
