1 Name: Date: SUMMER ALGEBRA II ASSIGNMENT ONLY REQUIRED FOR ADVANCED ALGEBRA II & HONORS ALGEBRA II The following review assignment is required to be completed by ALL students who plan on taking Advanced Algebra II or Honors Algebra II next school year. The goal of this assignment is to review the key components of Algebra I necessary for success in Algebra II. In addition, Section 2 is designed to prepare students for questions they will encounter on the PSAT (October 10 th, 2018) and SAT examinations. Due Date: Tuesday, September 11 th The packet will be collected and graded by your teacher. Record your answers on the answer sheet provided (pages 10-12) and show all work in the boxes provided for each question. ALL WORK is required for full credit. If you need additional resources to assist in completing this assignment, it is STRONGLY RECOMMENDED you utilize all the resources found at The Math Lab will be open after school starting on September 7 th in the 9/10 Library after school from 2:15-3:00pm on Mondays, Tuesdays and Thursdays. Please contact Mr. Michael Concilio mconcilio@srsd.net if you have questions or concerns over the summer. 1
