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.

Teacher's Guides 1 to 5 are designed to help teachers understand the course material and prepare for the day's lessons. The lessons have been developed according to the approach and methodology central to the series. Detailed, stepbystep lesson plans and introductory content are provided to assist teachers in using the Primary Mathematics program.

Our recommendation:
The Teacher’s Guide can be easily adapted for any setting. They are recommended for all users, particularly firsttime users, whether in a home or classroom setting since they provide valuable information and ideas for presenting the concepts concretely, along with background information, reinforcement activities, mental math pages, and other resources. They round out and add to the material in the textbooks and workbooks. They will be particularly useful for parents/ teachers who have not used earlier levels of the program. Some of the activities that involve multiple students will have to be adapted for a home setting.
