Question 7

Ramona,an 8-year-old with autistic characteristics,exhibits many difficulties in the area of social communication.She is high-functioning academically and enjoys activities involving repetitive movements and math calculations.Her teachers were concerned that Ramona would have difficulty participating and completing activities in a regular classroom.Ramona would sob,cover her ears,and rock in her chair when there was too much visual and auditory stimuli or when she did not know an answer to a question.When the teacher asked her to complete a math facts worksheet,the entire class was amazed to see that Ramona completed the math problems within a minute.From that point forward,Ramona became the "math" leader of the class,which not only increased her self-confidence but increased her social interaction with peers as well.What is Ramona's niche in the following scenario?
