Dimensions Math 2B Home Instructor’s Guide

This 166-page guide supports parents and educators teaching the second half of second-grade mathematics using Singapore's proven instructional methods. Written by experienced Singapore math educators, the guide is intentionally more concise and accessible than traditional classroom teacher's guides, making it practical for home and one-on-one instruction. Each lesson includes background notes that clarify mathematical concepts, detailed teaching suggestions, and structured activities that follow Singapore's CPA (Concrete, Pictorial, Abstract) progression, incorporating number bonds, bar models, and mental math strategies.

The guide's lesson structure walks through Chapter Openers that introduce concepts, Think sections where students explore multiple problem-solving approaches, Learn segments presenting solutions with clear definitions, and Do activities for practice and discussion. Complete answer keys for both Textbook 2B and Workbook 2B are included, along with references to printouts that can be downloaded at no cost to supplement instruction. These printouts provide additional practice materials and visual aids that enhance the hands-on learning approach.

Designed specifically for the second half of the school year, this guide builds on concepts from 2A while preparing students for third-grade mathematics. The curriculum emphasizes deep conceptual understanding rather than rote memorization, using engaging visuals and logical sequencing to help students develop mathematical reasoning skills. The discussion-based approach encourages students to articulate their thinking and explore different solution methods.
