# Dimensions Math for Grades 6-8

The Dimensions Mathematics is a remake of the original Discovering Mathematics. This course follows the Singapore Mathematics framework while also covering topics in the Common Core State Standards. The revision is currently in progress, with grade 6 being developed to accompany grades 7 and 8 courses.
The 6A textbook provides a place to go after finishing 5B in the Primary Math CCSS edition and is the bridge to levels 7 and 8 content. Currently, the 6A and 6B textbooks are only available-contact us for availability of other grade 6 components. Some new topics have been added and others have been rearranged between levels: some US measurement is included (metric is still dominant) and terminology reflects the more common US usage and spelling. Some of the additional topics are in the areas of numbers and operations, solutions of linear equations and inequalities, graphs of linear functions and relations, measurement, and data analysis. Some topics that were once found in books 1 and 2 of the original Discovering Mathematics series are now found in grade 8 of Dimensions Mathematics, but no topics have been removed. Students completing Dimensions Math 8 should be prepared for second-year algebra or geometry at the high school level.

Textbooks for this series are full color and chapters are divided into lessons. The amount of time you take for each lesson is not indicated, but you will want to finish one textbook per semester. Each chapter begins with an introduction to the concept or topic and lists the learning outcomes for the chapter. Each lesson includes an explanation with examples for the topic or concept, and "Try It", which is a question similar to the example. A variety of side notes are found in the margins. For example, "Math Web" includes a link for additional information, "Remarks" lists key learning points, "Recall" asks students to remember earlier presented content, "Discuss" is a thinking question related to the topic, and "Math Bits" states an interesting fact related to the topic. You will find an exercise for every lesson that includes "Basic Practice" (direct application of the concept), "Further Practice" (more challenging questions with application of concepts), "Math@Work" (practice with integrated concepts in practical situations), and "Brainworks" (higher order thinking questions that involve an open-ended approach to problem solving). Occasionally a "Class Activity" introduces new concepts through cooperative learning methods. At the end of each chapter you will find "In a Nutshell," which summarizes important rules and concepts from the chapter for easy review; a "Review Exercise" that offers a variety of integrated questions for students to apply chapter concepts; "Extend Your Learning Curve" that offers an opportunity for individual research; and "Write in Your Journal" that offers questions for reflection on chapter content. An answer key is found at the back of the book.Students will begin using a calculator (TI-30Xa is used for examples) and the Geometer Sketchpad (item # 034839)

Workbooks offer additional practice for each lesson and include Basic, Further, Challenging, and Enrichment sections the latter being the most challenging problems. Answers are listed in the back of the workbook for your convenience. If you would like more complete, worked solutions to the problems in the workbook, a Workbook Solutions is available.

Teaching Notes & Solutions offer fully worked solutions for "Try It", "Class Activity", "Basic Practice", "Further Practice", "Math@Work", and "Brainworks" exercises found in the textbook, as well as the "Review Exercise" for each chapter. The teaching notes are found in the front section of this book. It includes a suggested approach for each chapter and a brief suggestion (about a paragraph) for each lesson and what the student should gain from the lesson. I read on the publishers website that there is a weekly schedule found in this book, but I can find it nowhere. There are just the very brief teacher notes for each chapter and solutions. There are no tests written for this new edition, but you could use your chapter reviews for assessment purposes.

Keep up with the standards and teach good, solid math concepts with Dimensions Mathematics. ~ Donna/Deanne
