The following learning progression is based on meeting the cluster on Algebra under ‘Solving Equations and Inequalities in one Variable’ standard under the Reasoning with Equations and Inequalities math domain. This cluster has been taken from the Common Core State Standards for Mathematics. The book where I got activities or homework problems from is called Algebra I: Expressions, Equations, and Applications by Paul A. Foerster. The activities are focused on assuming this is a 9th grade class; however, this may vary.
