Concrete-Pictorial-Abstract (CPA) approach

The Concrete-Pictorial-Abstract (CPA) approach is a step-by-step method used in teaching mathematics. It begins with concrete, hands-on experiences using physical objects like blocks or counters to help students understand concepts. Next, students move to pictorial representations, such as drawings or diagrams, to visualize the idea. Finally, they progress to abstract symbols and formulas, like numbers and equations, to formalize their understanding. This progression builds a deep, connected understanding of mathematical concepts, making learning more effective by gradually shifting from tangible to symbolic understanding.
