Overview
Unit description, learning objectives, and skills.
Unit 0 — Foundations is the launchpad for all of Algebra 1. Before solving equations or graphing lines, you need a solid command of the building blocks: variables, expressions, the order of operations, real number classification, properties of operations, exponent rules, and scientific notation. Work through every lesson in order — each one builds on the last.
Learning Objectives
By the end of this unit, you will be able to:
Skills You Will Master
Real-World Connection
Every skill in this unit is a tool you will use throughout Algebra 1 and beyond. Order of operations prevents calculation errors in science labs. Scientific notation is how astronomers describe distances between stars and how chemists measure atoms. Properties of operations are the rules that make mental math fast. Mastering these foundations now means every future unit will feel manageable instead of overwhelming.
