Singapore Math: Primary Math Textbook 4B Common Core Edition
Singapore Math Primary Mathematics: 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.
