1 Algebra 1B Summer Review Packet Algebra 1: Algebra 1 teaches students to think, reason, and communicate mathematically. Students use variables to determine solutions to real world problems. Skills gained in Algebra 1 provide students with a foundation for subsequent math courses. Students should have a scientific calculator to help them throughout the course, but should be able to complete most of this packet using mental math. In May, students will be required to take the Keystone Algebra 1 Exam. Passing this exam is a state requirement for graduation.
