The Curriculum

The original Primary Mathematics curriculum was created by the Singapore Ministry of Education and written by a team of Singapore teachers. Singapore 4th grade students who participated in TIMSS (Trends in International Mathematics and Science Study) in 1995, 1999 and 2003 scored top place for mathematics. They were using the Primary Mathematics series.

There are currently three editions of Primary Mathematics series in the U.S. All three have been used successfully in U.S. schools and homes.

Primary Mathematics follows the five key learning models integrated in the Singapore math approach: Concrete-Pictorial-Abstract approach, model drawing, teaching to mastery, spiral progression and metacognition.

The Components

Primary Mathematics series of elementary math textbooks and workbooks is meant to be part of a system of learning in which adult supervision and independent practice go hand in hand. Students are provided with the necessary learning experiences beginning with the concrete and pictorial stages, followed by the abstract stage to enable them to learn mathematics meaningfully. This approach encourages active thinking process, communication of mathematical ideas and problem solving, which helps develop the foundation students will need for more advanced mathematics.

Practice exercises are designed to provide the students with further practice after they have done the relevant workbook exercises. Review exercises are provided for cumulative reviews of concepts and skills. All the practice exercises and review exercises are optional exercises.

The teacher's guides 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, step-by-step lesson plans and introductory content are provided to assist teachers in using the Primary Mathematics programs.

Primary Mathematics U.S. Edition, Standards Edition and Common Core Edition

Primary Mathematics U.S. Edition is an adaptation from the original edition used in Singapore but has a few added sections for U.S. customary measurements. It uses American spelling and conventions.

Primary Mathematics Standards Edition meets the 2006 Mathematics Contents Standards for California Public Schools issued prior to the writing of Common Core State Standards (CCSS). Primary Mathematics Standards Edition was adopted as an approved textbook by the California State Board of Education in 2007 for grades 1-5. It is similar to the U.S. Edition with some added units in probability, data analysis, negative numbers, and coordinate graphing.

Primary Mathematics Common Core Edition aligns with Common Core State Standards. Only minor changes were made to scope and sequence, but this edition is not interchangeable with earlier editions. The format for the Teacher's Guides for the Common Core Edition have been updated to include student materials, making them wraparound guides.
