Primary Mathematics Common Core Edition is based on the highly successful Primary Mathematics series from Singapore. The use of Primary Mathematics has contributed to Singapore's first place ranking in the Trends in International Mathematics and Science Study (TIMSS) in 1995, 1999, and 2003. With the support of Marshall Cavendish Education mathematics materials, developed using the Singapore approach, students in Singapore continue to rank top in various international studies, including the most recent 2011 TIMSS results.
This Primary Mathematics series has been updated to align with the Common Core State Standards for mathematics.
Designed to equip students with a strong foundation in mathematics and critical thinking skills, the Primary Mathematics Common Core Edition program offers an integrated solution to different learning needs in the classroom for Kindergarten and Grades 1 to 5.
The above is extracted from Primary Mathematics Common Core Edition with permission from the publishers.
Extra Practice Grades 1 to 5 consolidate and reinforce the mathematical skills taught in the Primary Mathematics series. The short and topicspecific exercises enable instructors to assign work only in topics for which the students need more practice. The simple language used allows students to review mathematics with minimal guidance.

Our recommendation:
Extra Practice for Primary Mathematics Common Core Edition 1A5B books are recommended as a source of reteaching and extra practice of the skills taught in the Primary Mathematics textbooks. They can be used for review for tests, to review concepts taught earlier, as a means to keep parents aware of what is being taught in school with example problem sets, or as a summer math book to keep concepts fresh. They are not recommended as a primary teaching resource. Though each unit does contain “friendly notes” reviewing the concepts, these are not sufficient alone for learning the concept for the first time.
