Dimensions Math 4B Workbook

The Dimensions Math 4B Workbook provides second-semester fourth-grade practice across seven chapters: Measurement, Area and Perimeter, Decimals, Addition and Subtraction of Decimals, Multiplication and Division of Decimals, Angles, Lines and Shapes, and Properties of Cuboids. This 210-page workbook follows the Singapore Math methodology, using a Concrete-Pictorial-Abstract approach that builds from hands-on understanding to visual representation to abstract thinking.

Each lesson includes four distinct sections that increase in complexity: Basics reviews core concepts from the textbook, Practice reinforces learning through progressively challenging problems, Challenge offers enrichment for students ready to extend beyond grade-level expectations, and Check provides opportunities for self-assessment. The grayscale pages incorporate strategic imagery and drawings to support visual problem-solving. Students work at their own pace, and the differentiated structure recognizes that not every student will complete every problem—lessons are designed for flexible pacing based on individual needs.

Answer keys are available separately in the corresponding Teacher's Guide or Home Instructor's Guide. This workbook pairs with Dimensions Math 4A to complete the fourth-grade curriculum and corresponds directly to the Dimensions Math 4 textbook material.
