What sequence of the following instructions should be followed in development of a mathematical concept in elementary classes? I. Drawing pictures II. Using symbolic representation III. Providing experiences IV. Explaining through language

The correct pedagogical sequence in mathematics begins with concrete experiences (III), followed by language to describe what was experienced (IV), then pictorial/diagrammatic representation (I), and finally abstract symbolic representation (II). This Concrete-Pictorial-Abstract (CPA) approach, also known as Bruner's enactive-iconic-symbolic progression, helps children build deep mathematical understanding by moving from concrete to abstract gradually.
