This is a great activity for any age! The booklet contains directions of assembling the activity using PASS Software for PRC AAC users. It also includes a hypothesis page (I think... big go up high/ little go up high) and a right/wrong statement page. The last page of the booklet includes a 24 location manual board to use during the activity to work on phrases - put in big, put in little, blow it up, etc. My clients and their siblings love this activity!
