Primary Mathematics is the original math curriculum that put Singapore at the top of international math tests. This renowned series has two decades of proven results in the U.S.

Primary Mathematics epitomizes what educators love about the Singapore math approach, including the CPA (Concrete, Pictorial, Abstract) progression, number bonds, bar modeling, and a strong focus on mental math.
