Concrete- Representational- Abstract

Concrete Representational Abstract (CRA) is a three-step sequential instructional approach that has been found to be highly effective in teaching math concepts. Students move from working with concrete materials (virtual or physical manipulatives) to creating representational drawings to using abstract symbols like numbers.
