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. methods and the interferences in Math, which are considered to be effective, in order to help people with disability or/and special educational needs, realize and understand math senses, targeting in deploying their workforce, so that they can participate in many different social activities [2].According to many scientific findings, one of the most effective strategies in interfering Math, is the teaching method of CRA (Concrete-Representational-Abstract), which targets in human development and evolution through the Discovery Learning. According to Bruner, each stage of the Discovery Method, represents also a stage of the human development path, their way of thinking, but also the teaching tools that are being used [3] [4].
