It’s a Common Core Revolution – Ensure complete coverage
On Core Mathematics provides complete coverage and comprehensive instruction strategies for implementation of the Common Core State Standards. Activities and direct instruction is also embedded to ensure implementation of the Standards for Mathematical Practice.
Accessible for all Teachers and Easy to Use
This program makes it easy to incorporate Common Core content and the Standards for Mathematical Practice into your current curricula. The Teacher’s Editions provide correlations, math background information and teaching notes for every lesson.
Assessments and Beyond
On Core Mathematics make math meaningful and relevant by actively engaging your students in their math. Explanation, Reflection, and Justification as well as Preparation for common assessments is found throughout the texts and will guarantee a successful transition to the Common Core State Standards.

Common Core
On Core Mathematics is an innovative, instructional solution that develops students' understanding of the Common Core State Standards in an interactive format, while integrating the Standards for Mathematical Practice. Students actively participate in lessons that use clear, steppedout models and incorporate manipulatives when appropriate, to develop a deeper understanding of the mathematics.
Each lesson includes opportunities for understanding and practice. Practice focuses on helping students master both Standards for Mathematical Practice and includes opportunities for realworld problem solving. Problem solving is integrated into every lesson as well as in special problemsolving lessons. Problemsolving lessons help students pull together concepts and skills and apply them to realworld situations. Reflect questions challenge students to think about the mathematics that they are studying and share their understanding with the class.

On Core Mathematics for Grades 6–12
Interact sections allow students to actively participate in every aspect of a lesson. This interactivity promotes a deeper understanding of the mathematics. Reflect questions challenge students to think about the mathematics that they are studying and share their understanding with the class. Problemsolving connections help students pull together the mathematical concepts and skills taught in the unit and apply them to realworld situations. On Core Mathematics integrates the Standards for Mathematical Practice throughout the students' learning, helping students master both content and practice standards.
Teacher Editions provide lesson background for all topics, questioning strategies to prompt classroom discussions, strategies on how to integrate the Standards for Mathematical Practice into every lesson, and instruction on how to help students avoid common errors.
 Each lesson introduces the content standard(s) that apply, the prerequisite vocabulary needed, and the background information in the context of the Common Core State Standards, as well as ways to introduce the topic and connect it to prior learning.
 Questioning strategies prompt discussions that help students develop and demonstrate a deeper understanding of math concepts and provide onthespot intervention when necessary.
 Suggestions for integrating Standards for Mathematical Practice appropriate to a particular lesson are highlighted and explained in the Teacher Edition.
 On Core Mathematics provides strategies and tips within the Teacher Edition to help students avoid common errors in math.
