Dimensions Math 1B Workbook

This 192-page workbook serves as the second-semester companion to the Dimensions Math 1B Textbook, providing structured independent practice for first-grade students. Each lesson follows a four-part progression: Basics reviews fundamental concepts and shows how they were taught in the textbook; Practice offers additional reinforcement; Challenge presents optional enrichment problems suitable for homework or extended learning; and Check allows students to confirm their understanding before advancing. Problems within each section increase progressively in difficulty, and the textbook includes pencil icons that link directly to corresponding workbook exercises.

The Dimensions Math series emphasizes the part-whole concept and circle diagrams throughout, building strong number sense and problem-solving foundations from the start. This pedagogical approach helps first-graders understand how numbers relate to each other and develop flexible mathematical thinking. Students work at their own pace through each lesson's sections, and not every student needs to complete every problem—the differentiated structure accommodates varying learning speeds while maintaining rigor.

The workbook features perforated pages for easy removal and does not include an answer key (found separately in the Home Instructor's Guide or Teacher's Guide). Teachers and parents should note that students may arrive at correct answers using different methods than those shown in the guide.
