## Table of Contents

In CK-12 Middle School Math Concepts – Grade 6, the learning content is divided into concepts. Each concept is complete and provides 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 explore more practice. There are also video links provided to give students an audio/visual way of connecting with the content.
