Think! Mathematics Grade 1 is a 4-book set composed of Textbooks A and B, and Workbooks A and B adapted from the New Syllabus Primary Mathematics series that has been approved by the Ministry of Education (MOE) in Singapore. Written in accordance with extensively-researched approaches used in Singapore, it adopts a spiral design with the integration of the concrete-pictorial-abstract (C-P-A) approach, careful variation and the use of problem solving, which are integral features of the learning process.

Based on time-tested learning theories, this series incorporates the use of concrete manipulatives and group work. With a three-part lesson format (Anchor Task, Guided Practice and Independent Practice), lessons are designed to be bite-sized for effective learning.
