The project below is a research on how to apply the CRA method (Concrete- Representational-Abstract), in math, on a student of toddler age with intellectual disability. Children with intellectual disability have a limited understanding of math senses, resulting in facing a lot of difficulties in various daily tasks. Primary math senses are directly related with obtaining skills during toddler age, such as counting and connecting numbers and quantities. Through this essay we are aiming in researching if there can be an improvement in understanding primary math senses after applying the CRA method (Concrete-Representational-Abstract). More specifically, researchers have focused a lot on creating connections between actual quantities, counting numbers and the use of official math words and symbols.
