This textbook addresses the underexplored field of mathematics education for students with disabilities—specifically Visual Impairment, Intellectual Disability, and Autism Spectrum Disorder. It examines teaching and assessment strategies, including Braille, concrete materials, and high-tech tools for blind and low-vision learners. For students with Intellectual Disabilities, it surveys global practices, emphasizing mathematical literacy for autonomy. The section on Autism Spectrum Disorder explores definitions, learning challenges, and pedagogical strategies, supported by a systematic review. The book also discusses co-occurring disabilities and their impact in inclusive classrooms. Ideal for regular school teachers, teacher trainers, and university students, it offers practical insights, didactic activities, and case studies for both in-person and distance learning.
