Adkins, who has a child with autism and is associated with a company that facilitates training seminars on autism spectrum disorders for parents and professionals in New Zealand, and Larkey, a teacher who has worked with children with autism in Australia, outline strategies and tools for teaching math concepts to children with autism spectrum disorders and other developmental delays. They explain how to use a child's special interests and make math fun when teaching early concepts that will prepare the child for the normal school and preschool curriculum. They present concepts in a progressive order: colors, shapes, categories, numerals, sequencing and order, numbers, visual math addition, attributes to compare, positions, and money. Each includes lessons with materials lists, steps, tips, notes, assessment, and worksheets. The last lesson demonstrates how to use everyday situations to teach math.
