Language Lab: Plurals is the fourth of a series of apps featuring the stages of language development. This app focuses on the development of Stage Three or Intermediate language skills and is a great tool to use with augmentative communicators.
This “Plurals” app is designed for individuals who are beginning to use simple sentences, placing them within Stage Three of Language Development. At this stage, the person is adding more words to their vocabulary (including prepositions – e.g., in/on), and increasing their language markers, such as plurals and verb endings. The mean (average) length of utterance grows to 2.75, with typical phrases ranging from two to three words.
Some expected outcomes of Stage Three include speaking in complete simple sentences, knowledge and expression of plural noun concepts, and the use of prepositions to show position.
