Arnie and His School Tools creates an environment that is accepting of students with sensory modulation difficulties, including many on the autism spectrum. Occupational therapists, teachers and parents will find this book an engaging way to introduce elementary students to basic sensory tools used to help children focus in classroom settings, such as fidgets, chewy pencil toppers, and weighted vests.Additional resources are provided at the end of the book, including definitions of sensory processing and sensory modulation disorder, suggested discussion questions, and lists of related books and websites.
