Dear Future Algebra 2 Students and Parents: The Algebra 2 teachers in the Tigard-Tualatin School District look forward to working with you next year. It is our strong desire to help all students to achieve success in Algebra 2! Algebra 2 is a fast-paced course and now, with the new Common Core State Standards, Algebra 2 is becoming increasingly challenging as well. Algebra 2 students are now expected to have more advanced levels of conceptual understanding and to use advanced problem-solving skills to tackle more complex algebraic questions. In order for students to be successful in Algebra 2, they must have quality understanding of many math concepts, including number sense, graphing and solving linear and quadratic equations and inequalities, and functions and their domains and ranges. Without these skills, students are likely to struggle greatly with the pace and material covered in Algebra 2. In some cases, students may be withdrawn from Algebra 2 in order to learn the requisite skills in Algebra 1. The attached Algebra 2 Readiness summer packet is designed for students to review the skills necessary to be successful in Algebra 2. Completion of this Algebra 2 Readiness summer packet is highly recommended so that students are fully prepared for the challenges they will encounter next year in Algebra 2. Algebra 1 is the foundation for advanced math courses, including Algebra 2. Students who struggle to complete the Algebra 2 Readiness summer packet, which contains many basic Algebra 1 concepts, should strongly consider enrolling in Algebra 1 for the upcoming school year. With the implementation of the new, more rigorous Common Core State Standards for Algebra 1 and Algebra 2, next years’ students must have an even greater understanding of Algebra 1 than before in order to be successful in Algebra 2. The placement of students into the appropriate course, whether it be Algebra 1 or Algebra 2, is critical for student success. Parents can contact their student’s counselor to make schedule changes, if needed. The Algebra 2 Readiness summer packet is designed to include explanations of concepts and example problems so that students can relearn material they may have forgotten. Students can find additional help on the Holt textbook website by reviewing related examples and/or watching video tutorials. The Algebra 2 Readiness summer packet includes textbook section numbers at the top of each page, which correlate to the Holt Algebra 1 textbook. Use these section numbers to navigate to the appropriate areas of the Holt textbook website, which can be accessed using the following information: Website: my.hrw.com (Be sure to omit the “www”.) Username: tuhsalgebra Password: ilovemath Students can check their work with the answer key provided at the end of the packet. The answer key is meant to be a tool for students to check their progress and identify areas where further work is needed. Students should be sure to show their work throughout the packet and should not rely solely on the answer key during completion of the packet. The Algebra 2 Readiness summer packet is also available online on the Tigard-Tualatin School District website. We look forward to working with fully prepared Algebra 2 students and guiding them through a successful year in Algebra 2. Sincerely, Algebra 2 Teachers of the Tigard-Tualatin School District
