Learn as much as you can about the preschooler with ASD. Testing and observations are useful. It is imperative to become familiar with the child's abilities and limitations, as well as her strengths and weaknesses. Understanding whether the child is socially or cognitively low or high functioning is crucial for setting expectations and designing a plan to teach the child.
Gain an understanding of the preschooler's sensory development. Children with ASD often have difficulty with sensory integration, which can lead to behaviors such as rocking and hand flapping, and can cause them to act out when exposed to a sensory stimuli that is unpleasant. Observe what sensory stimuli she avoids or seeks out.
Establish a set preschool routine. Communicate the steps in the routine frequently with the child. Using picture icons to display the day's schedule is a good way to help the child understand the routine.
Minimize distractions. It can be easy for a child with ASD to become distracted, so reducing loud noises, classroom interruptions, and schedule changes can be less disruptive and bothersome to the child.
Consider teaching in a manner that allows a variety of learning styles to be successful. Many autistic children struggle with verbal communication, so using pictures is extremely helpful. When speaking to a preschooler with ASD, be specific and simple with your instructions.
Be flexible. Children with ASD often receive special services, like occupational therapy or speech therapy, so it is important to remain flexible when having the child leave and return to your class. If a preschooler with ASD is being disruptive or having difficulty remaining in class, you may need to be adaptive and use resources such as a school paraprofessional or a special education staff who is specially trained for helping children with learning differences and other conditions.
