The current research is designed to investigate the impact of a BBL theory training program on developing mathematical skills and scientific thinking of mathematic disabled students. The proposed training program works as an independent variable comprising (22) training sessions. The methodology of the proposed program is based on integration between (Caine and Cain's) principles of BBL and (Karen D. Olsen, Susas Kovalik's) principles of BCL. The dependent variables were mathematical and scientific thinking skills. The validity and reliability of both independent and dependent variables were checked and confirmed by a pilot study, the study sample was divided into two groups; a control group of 36 participants; (16 males, 20 females), and an experimental of 35 participants; (16 males, 19 females) both with an average age (13 years). The research design used quasi-experimental design. Results showed the effectiveness of the training program employed.
