Mathematics is integral to all areas of life, from functioning on the job to successful functioning in the community. It has been proved that high levels of mathematical and technical skills are needed for most jobs in the 21st century. Research shows that 5-10% of students have difficulties in mathematics and that the difficulties in mathematics are common in students with learning disabilities. The aim of this qualitative research was to describe procedure of application of specific cognitive learning strategies (Five pier spiral, Step by step, Method of simple numbers) adopted in process of encouraging child in mathematics and gain insight of contribution of strategy instructions in mathematics in 5th grade child with learning disabilities, though the perspective of family members, mother and grandmother. Cognitive strategies are chosen according to the needs of the child and learning with the student took place in the period from 11th March 2015 to 31st May 2016. For the purpose of evaluation, semi-structured interviews were applied as data collection methods and data were analyzed through a qualitative methodology. Monitoring the performance of teaching mathematics through specific cognitive strategies for student with learning disabilities in this study was conducted trough respect of perspective of mother and grandmother, in order to gain insight on how family members noticed changes in the way of acquiring knowledge, the attention of the child, the motivation for learning and success in the form of academic assessment in purpose to better monitor the functioning of the child and contribute to the quality organization of support for students with learning disabilities in mathematics. The findings of this research on the contribution of cognitive learning strategies in mathematics troughs the work with child with learning disabilities have pointed out following important determinants: Mastering mathematics, mastering mathematics after adopting cognitive strategies and the contribution of cognitive strategies. Based on the findings of research, recommendations for the improvement of learning mathematics in students with learning disabilities in mathematics were obtained.
