Grouping objects is an important skill, particularly for lower functioning children who have autism. The ability to group objects can be linked to activities that include turn taking and waiting. Grouping objects also assists students with autism to develop a greater understanding of characteristics or attributes.
The ability to group and categorize objects is often a prerequisite skill for work preparation activities at school and vocational training for post school options. Many students with autism may develop obsessions associated with sequencing or grouping highly desired objects. Students with autism often need to generalize a skill in a range of setting before the skill can be mastered.
