Enhance foundational skills with these comprehensive file folder activities designed for special education teachers and parents of autistic students. This resource, featuring clear instructions and printables, focuses on association and function through eight engaging tasks. Non-identical matching is employed to teach students how to sort items based on common features, fostering essential categorization and discrimination skills. The tasks are thoughtfully structured across three levels of "What Goes Together" and two levels each of grouping items by function and feature. This diverse set of activities promotes generalization and is suitable for early childhood or students with autism and special needs.
