The CRA Approach

The Concrete-Representational-Abstract (CRA) Instructional Approach is an intervention for mathematics instruction that research suggests can enhance the mathematics performance of students with learning disabilities. At Math Journeys, we know from experience that all students can benefit from this approach to mathematics instruction.

Concrete. The “doing” stage using concrete objects to model problems
Representational. The “seeing” stage using representations of the objects to model problems
Abstract. The “symbolic” stage using abstract symbols to model problems
