Dimensions Math 4 Workbook Bundle

This bundle contains the complete fourth-grade Dimensions Math workbook series, featuring both 4A and 4B volumes that correspond to first and second semester instruction. Built on Singapore Math methodology, these workbooks emphasize conceptual understanding through concrete-pictorial-abstract progression, number bonds, and bar modeling techniques. Each 200+ page workbook follows a structured format with Basics sections for foundational review, Practice sections for skill consolidation, Challenge sections with advanced problems, and Check sections for self-assessment.

Workbook 4A covers Numbers to One Million, Addition and Subtraction, Multiples and Factors, Multiplication, Division, Fractions, Adding and Subtracting Fractions, Multiplying Fractions and Whole Numbers, plus Line Graphs and Line Plots. The problems intentionally progress from fundamental concepts to increasingly complex applications, allowing students to build mastery at their own pace while developing mathematical reasoning skills.

Important note: Answer keys are not included with these workbooks and must be purchased separately through the Home Instructor's Guide or Teacher's Guide. The workbooks are designed to complement the corresponding Dimensions Math textbooks for complete curriculum implementation.
