# Chapter 7: Equations, Inequalities and Functions

**At Grade**Created by: CK-12

## Introduction

In Math 7, the learning content is divided into Concepts. Each Concept is complete and whole providing focused learning on an indicated objective. Theme-based Concepts provide students with experiences that integrate the content of each Concept. Students are given opportunities to practice the skills of each Concept through real-world situations, examples, guided practice and independent practice sections. There are also video links provided to give students an audio/visual way of connecting with the content. In this Chapter, students will engage with Concepts on writing expressions and equations, simplifying expressions, solving one-step equations, solving two-step equations, solving inequalities, identifying and understanding functions and graphing functions.
