As a Speech Language Pathologist, I have around 1 year of experience in dealing with children and teaching these children how to speak and communicate. I would be using more of an interesting and fun techniques and methods to teach my children where the sessions and classes will be more fun and entertaining other than making it least interesting for these children.
Making the sessions and classes more lively and teaching children with more environmental and generalisation examples would help these individuals understand what happens around them and not just what is taught to them in books or classes.
Children tend to get very bored and least interested in doing their works or when it comes to learning, so I would teach each of these using various interesting aspects which would be entertaining for the children.
