Dimensions Math 1–5 follows the same Singapore math approach as Primary Mathematics 1–6. It emphasizes the CPA (Concrete, Pictorial, Abstract) progression. It centers on the use of number bonds and bar models to solve word problems, and encourages the mastery of mental math to gain number sense, computational fluency, and logical thinking.
The problem solving processes of the learning tasks deepen and broaden student understanding of concepts (in contrast to the method of simply following an example to solve a similar problem). There is minimal vocabulary and textual information. Concepts are conveyed primarily through images and careful sequencing.
