This playlist contains several activities that will help prepare you for the Algebra 1 Keystone Exam. Many of these topics will be covered throughout the year. If there is an activity you don't recognize, there is a link on each page to a video lesson that should help you.
The Keystone Exam is Broken into two Modules that will take place over two days. Module 1 covers topics from "Numbers and Operations" and "Linear Equations and Inequalities." These broad topics include writing and solving linear equations, writing and solving systems of linear equations and inequalities, exponent rules and simplifying radicals.
Module 2 covers functions and statistics.
