think! Mathematics is a series of textbooks and workbooks written to meet the requirements of the latest Common Core State Standards. In tandem with adapted approaches used in Singapore to develop critical thinking, as well as problemsolving and analytical skills, students can gain a strong foundation to achieve the highest possible level of mastery of mathematics.
This series adopts a 3part lesson structure and a spiral design within and across grade levels. The concretepictorialabstract (CPA) approach and the infusion of funfilled activities help develop students’ cognitive and metacognitive skills. Newtrend questions and openended questions are included throughout the series to encourage analytical and lateral thinking.
