Singapore Math Primary Common Core Edition books have been updated where necessary to align with the CCSS. However, this does not mean that the content has been reduced in its level of difficulty. If CCSS called for content to be introduced at a later level, Singapore Math didn't move content from the earlier level, but rather simply revisits it more in-depth at the CCSS level. Singapore Math's Primary Math, Common Core 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. Concepts are introduced in the opening pages and taught to mastery through specific learning tasks; regular reviews help provide consolidation of concepts. Primary Mathematics, Common Core Edition Textbook 5B teaches students about decimals, volume, plots & graphs, percentage, and more. 176 pages, softcover. Grade 5. These non-consumable textbooks are meant to be completed with adult supervision and teaching. The sold-separately Primary Mathematics Standards Edition 5B Workbook is directly correlated with this textbook and should be used alongside this text, as it includes the learning tasks, practice and review problems necessary for mastery. Please The Primary Mathematics Common Core Edition resources cannot be used interchangeably with the Primary Mathematics U.S. Edition or Standard Edition resources. Answers are in the sold-separately Primary Mathematics Common Core Edition Teacher's Guide 5B.
