think! Mathematics is a series of textbooks and workbooks written to meet the requirements of the latest National Standards. In tandem with adapted approaches used in Singapore to develop critical thinking, as well as problem-solving and analytical skills, students can gain a strong foundation to achieve the highest possible level of mastery of mathematics.

This series adopts a 3-part lesson structure and a spiral design within and across grade levels. The concrete-pictorial-abstract (C-P-A) approach and the infusion of fun-filled activities help develop students’ cognitive and metacognitive skills. New-trend questions and open-ended questions are included throughout the series to encourage analytical and lateral thinking.
