Dimensions Math 4B Home Instructor’s Guide

The Dimensions Math 4B Home Instructor's Guide provides comprehensive teaching support for parents and tutors working with fourth-grade students in home settings. This spiral-bound resource includes detailed background notes, lesson-by-lesson suggestions, teaching tips, and complete answer keys for both the 4B Textbook and Workbook. Designed specifically for one-on-one instruction rather than classroom use, the guide offers flexible approaches that adapt to individual pacing and home learning environments.

The 4B semester covers measurement, area and perimeter, decimals (including addition, subtraction, multiplication, and division), angles, lines and shapes, and properties of cuboids. The guide follows Singapore Math's concrete-pictorial-abstract methodology, walking parents through each lesson's five-part structure: Think (introducing concepts through real-world problems), Learn (teaching with manipulatives and visual models), Do (guided practice), Activities (optional reinforcement), and Workbook (independent practice). This mastery-based approach ensures students develop deep conceptual understanding before advancing to new topics, with particular emphasis on word problems that build mathematical reasoning skills.
