Primary Mathematics (2022 Edition) is a K-5 program written to reflect the current practices of math instruction in Singapore. The content and lesson structure are completely new and do not resemble those of previous Primary Mathematics editions. The development of this series was led by Dr. Kho Tek Hong who helped create the original Primary Mathematics series. 

Like previous editions of Primary Mathematics, the program builds strong problem solving, critical thinking, and computational skills through classic Singapore math methods, such as the concrete-pictorial-abstract approach and bar modeling. The scope and sequence is similar to previous editions of Primary Mathematics, and topics are aligned to state and national standards.
