Use specialized equipment. Different companies offer a wealth of options for children with disabilities, like all-terrain wheelchairs, lighter rackets for tennis or badminton or balls with beepers inside for children who are visually impaired. PE Central, a website for physical educators, also has a list of suggestions for making homemade equipment, like using a dowel rod and a 2-liter soda bottle to create a bat with a large hitting surface.
Adjust the rules of the game to accommodate students with disabilities. Texas Woman's University, which offers a major in adaptive physical education, has several suggestions, such as keeping basketball quarters to 5 or 6 minutes or limiting bowling to four or five frames for children who don't have the stamina for longer matches.
Shrink the size of the area where the game or sport is played. For example, in golf, this may mean decreasing the number of holes that are played or placing the holes closer to tees. Other examples would be allowing children playing tennis to stand closer to the net when they serve or reducing the distance between bases in softball or baseball.
Change the equipment that is normally used for the sport. This can help instructors adapt games and activities for children with special needs without buying anything new. You could use inflatable beach balls for volleyball or soccer games, suggests PE Central.
