think! Mathematics is a series of textbooks that are based on various learning theories.
Designed in accordance with extensively-researched approaches used in Singapore, these books adopt a spiral design with the integration of the Concrete-Pictorial-Abstract (C-P-A) approach.
A three-part lesson structure of Anchor Task, Guided Practice and Independent Practice are adopted. ICT, concrete aids and manipulatives are incorporated. Students have opportunities to hone problem-solving skills and apply Mathematics in real-world contexts.
Combining the effectiveness of teaching pedagogies and innovative ideas, the content has been aligned to the Common Core State Standards.
