The school must make sure your child takes part in extracurricular services and activities with children who do not have disabilities, as much as is appropriate for your child's needs. It must also make sure your child has the supplementary aids and services the IEP team decides are appropriate and necessary to take part in nonacademic settings, such as meals and recess.
“In providing or arranging for the provision of nonacademic and extracurricular services and activities, including meals, recess periods, and the services and activities set forth in § 300.107, each public agency must ensure that each child with a disability participates with nondisabled children in the extracurricular services and activities to the maximum extent appropriate to the needs of that child. The public agency must ensure that each child with a disability has the supplementary aids and services determined by the child's IEP Team to be appropriate and necessary for the child to participate in nonacademic settings.”
