# Chapter 5: Number Patterns and Fractions

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

## Introduction

In Math 6, 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. In this fifth chapter, Number Patterns and Fractions, students will engage in many Concepts including factor pairs, divisibility, prime and composite numbers, prime factorization, greatest common factors, equivalent fractions, simplifying fractions, multiples, and writing fractions in different forms.
