This activity is great for targeting several goals. Describing pictured actions using the correct subject-object, as well as the present progressive verb, and the copula verb "to be." Often kids with language impairment leave out helping words such as "the" and "is." Individualizing the words in boxes, provides the child with a visual cue. Furthermore, this helps with learning site words, as the kids are able to cut and paste the matching words. These sentences are semantically reversible. Semantically reversible sentences are prone to misinterpretation and take longer for typically developing children and adults to comprehend; they are also particularly problematic for those with language difficulties such as aphasia or Specific Language Impairment. These sentences have an interesting property in that when the subject and the object are swapped or reversed (e.g., “The dog is chasing the cat” "The cat is chasing the dog"), these sentences remain meaningful, although the exact meaning of the sentence is changed (for instance, the animal doing the chasing changes). By contrast, in a nonreversible sentence (e.g., “The dog chews the bone”;), swapping the subject (e.g., dog) and the object (e.g., bone) results in a sentence with no real meaning (“The bone chews the dog”).
