Children with developmental disorders do not acquire the same way as do children with an age-appropriate intellectual level, so it needs to be carefully chosen what kind of methods to use and in what way to teach the children. For preschool children, the most efficient and simplest method of teaching mathematics is a playful approach to learning activities. The purpose of this work was to create a set of materials to support the teaching and learning of mathematical concepts for preschool-age children with special needs. There were created learning materials such as Train, Shelves, Long and short, Butterflies and cars, Wide and narrow road, and board game Owls. All the learning materials, including a board game, are laminated and most of them are provided with velcro strips to stick different parts. All the learning materials are tested on preschool-age children and asked specialists and teachers, who work with children with special needs, to give their expert evaluation. Learning materials support teaching mathematical concepts for preschool-age children with special needs.
