Dimensions Math 4A Workbook

The Dimensions Math 4A Workbook provides 218 pages of independent practice aligned with Singapore Math methodology, covering the first half of fourth grade. This workbook progresses through nine chapters: Numbers to Millions, Addition and Subtraction, Multiples and Factors, Multiplication, Division, Fractions, Adding and Subtracting Fractions, Multiplying a Fraction and a Whole Number, and Line Graphs and Line Plots. Each lesson is structured with four sections—Basics, Practice, Challenge, and Check—allowing students to build from fundamental concepts to increasingly complex problems at their own pace.

The Basics section reviews core concepts from the textbook and demonstrates how these concepts were taught, making it particularly useful for parents working with students at home. Practice problems provide reinforcement, while Challenge problems offer optional enrichment for advanced students or homework assignments. The Check section allows students to confirm their understanding. This differentiated approach recognizes that not every student needs to complete every problem; students can work through what they need based on their individual mastery and time constraints.

The workbook corresponds directly to the Dimensions Math 4A textbook and represents half of the grade 4 curriculum (the companion 4B workbook covers the second semester). Answer key sold separately. The 8.5 x 11 inch format provides ample workspace for problem-solving, with grayscale pages featuring visual imagery to support comprehension. Teachers should note that students may arrive at correct answers using different solution methods than those shown in the Teacher's Guide—all valid approaches should be accepted.
