Singapore Math's *Primary Math, Standards Edition* series features the Concrete> Pictorial> Abstract approach. Students begin by learning through concrete and pictorial means before moving into abstract thought and development, which encourages an active thinking process, communication of mathematical ideas, and problem solving. The spiral approach encourages mastery through the modeling method, which helps students to visualize problems as they work on specific skills.

Primary Mathematics, Standards Edition Book 2A teaches students numbers to 1000, addition & subtraction, measuring length & weight, 2s and 3s multiplication tables, and dividing by 2 or 3. 135 full-color pages with index, softcover. Grades 2-3.

Adapted from Singapore Math's *Primary Mathematics* series, these workbooks have been aligned with the Mathematics Framework for California Public Schools. *Standard Edition* books differ in that they include units on probability and data analysis, as well as negative numbers and coordinate graphs. These skills are not taught in the Primary U.S. Edition.

These non-consumable textbooks are meant to be completed with adult supervision and teaching. Featuring the learning tasks, practice and review problems, the sold-separately Primary Mathematics Standards Edition Workbook 2A is designed to be used alongside this text for necessary practice.
