The Primary Math International Curriculum

Primary Math International focuses on problem solving, encouraging students to try problems and find solutions on their own, with support and guidance from the teachers. Priority is placed on developing the student’s ability to think for themselves, while making sure that they have thoroughly understood the fundamental concepts. The goal of Primary Math International is to develop the student’s Will and Skill to use Math for Life.

The Concept:  Four Steps to Learning through Problem Solving

Students learn each topic through four steps:  Try, Understand, Apply, Master.  These steps reflect "learning through problem solving" in actual classroom activities.

  • Try is a step of responding to a new challenge.  Students try to solve a problem involving a new topic by themselves, and then they discuss ideas with the class.  At the end of a lesson they reflect on their findings.  Through this process they grasp the learning task of the new topic.
  • Understand is a step of building conceptual understanding.  Students organize key concepts and procedures they have learned from the introductory problem.  Next, they deepen their understanding by working on problems that follow the pattern of the introductory problem.  Then they summarize their understanding in their own words.
  • Apply is a step of becoming proficient with the procedures.  Students solve problems with different situations and numbers, explain the procedures in their own words, and share creative ways to solve problems as well as common mistakes with the class.
  • Master is a step of mastering the topic so that the concepts and procedures can be used in various situations.  Students work on advanced problems that are more practical or that combine multiple concepts, and explain and evaluate solutions in small groups.  Finally, they review the entire topic and summarize what they have learned.

What's Unique:  Integration of Textbook and Notebook

The Lesson Book has plenty of writing space for students to record their calculations and thinking processes.  Grids are used on every page to enable students to write numbers and equations neatly so they can reflect on and examine their own thinking processes.

It is important for students to write down their own ideas and those of other students, and to verbally explain these ideas based on their notes.  Doing so helps students check, correct, and deepen their own understanding.  Therefore, in each learning step, there is a blank space for writing something related to the topic, and there are many activities that focuses on explaining.

Using Primary Math International, students will acquire not only knowledge of mathematics but also effective learning strategies.
