# Chapter 1: Using Algebra

## Introduction

In Math 8, the learning content is divided into Concepts. Each Concept is whole and complete providing focused learning on an indicated objective. Real-world Concepts involve the student in the learning objective of each Concept. Students are given opportunities to practice skills through real-world situations, examples, guided practice and independent practice sections. There are video links provided for Concept connections with technology. In this Chapter, students will engage with a variety of material including bar graphs, histograms, frequency tables, the order of operations, variable expressions, single-variable equations, perimeter, area, distance formulas, and problem-solving.

## Chapter Outline
