Textbooks develop concepts in increasing levels of abstraction. Each topic is thoughtfully introduced and extended through the use of exploration, play, and opportunities for mastery of skills. Features & Components: Chapter Opener: Each chapter begins with an engaging scenario that stimulates student curiosity in new concepts. This scenario also provides teachers an opportunity to review skills. - Lesson: Engaging imagery draws students into the concept of each lesson. - Exercise: A pencil icon at the end of the lesson links to additional practice problems in the corresponding workbook. - Review: A review of chapter material provides ongoing practice of concepts and skills. Note: Two textbooks (A and B) for each grade correspond to the two halves of the school year. Answer key not included. Soft cover. A & B Books: Our programs divide the school year into two semesters. “A” level books are for the first half of the school year. “B” level books are for the second half of the school year. You need both “A” and “B” material for a complete school year. Required Components: Textbooks, Workbooks, and Guides (either Home Instructor’s Guides or Teacher’s Guides) are all necessary components. These three elements each serve a unique function and work together to build math mastery.
