# Dimensions Mathematics Common Core Textbook 8A

The *Dimensions Mathematics* Common Core Textbooks emphasize the empowerment of students to learn math independently and effectively, a variety of approaches are used to help students master integrated pre-algebra, algebra, geometry, trigonometry, and advanced math topics. This series follows the Singapore Mathematics Framework as well as the topics in the **Common Core State Standards**.

Key Features:

- Worked examples followed by a "Try It!" question to ensure understanding.
- Lesson exercises that include the following exercise categories:
*Basic Practice*(simple questions involving a direct application of the concepts);*Further Practice*(more challenging questions);*Maths@Work*(questions that apply mathematical concepts to real-life situations);*Brainworks*(questions involving higher order thinking or an open-ended approach to problems).

- Review exercise, an "
*Extend Your Learning Curve*" activity, and "problem solving corner" exercises are also integrated throughout.

The answer key at the back of the book provides answers to the* Try It!* and the problems in the exercises for the Basic Practice, Further Practice, and Maths@Work questions. It does not include answers to the class activities, Brainworks questions, or the Extend Your Learning Curve activities; the answers can be found in Teacher's Notes & Solutions.

**Teaching Notes and Solutions** is a succinct and useful tool for educators. It contains teaching notes for each chapter, and fully worked solutions for all problems in the textbook. .
