The students followed a program involving modified schema-based instruction. The results show an improvement in the problem-solving skills of the three students, who achieved successful formal strategies associated with identifying the operation. We analyze the importance of adapting and/or emphasizing certain steps in the instruction process in order to tailor them to the difficulties of each student.}, publisher = {MDPI}, publisher = {Mathematics 2021, 9, 1814}, title = {Strategies for Solving Addition Problems Using Modified Schema-Based Instruction in Students with Intellectual Disabilities}, author = {Bruno, Alicia and Polo Blanco, Irene and González López, María José and González Sánchez, Jon}, }
