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.

Our recommendation:
Primary Mathematics Common Core Edition 1A5B textbooks and workbooks are suitable for both a classroom and home setting.
This series is recommended for those who want a solid, basic math program with a proven track record and an emphasis on concept development, mental strategies, and problem solving, and for those who want to be sure all the topics in the Common Core State Standards are covered. Students are given several approaches for solving problems and are encouraged to discuss their ideas and explore additional methods.
Students should use both the textbooks and workbooks. The nonconsumable textbooks provide activities, learning tasks, and some practice, while the consumable workbooks provide additional practice for consolidation or homework with room to work out the problems. In a home setting, parent/teacher involvement is essential for the success of this program since interaction and discussion are key elements to learning the concepts. The textbooks do not simply provide explanations and answers; instead they provide learning tasks that the student does with guidance. This series should generally be used with the help of the Teacher’s Guides which provide the background information and concrete introduction to the topics along with additional activities.
