Santino and I explored the properties of a half-filled/slightly deflated yoga ball today. We examined its surface texture, rolled it, squished it, threw it, rolled it down and off objects, sat on it, cradled it, and used it as a recliner. Santino enjoyed all the sensory-motor information he gleaned from manipulating and engineering the ball in various positions and operations. Throughout the discovery phases as he engaged with the ball, I narrated and repeated all the various terms and concepts that applied to our actions and operations. Santino repeated a few words and clearly enjoyed the stimulation received; he enjoyed the freedom to manipulate the large ball as he wished. At one point, as Santino reclined in it and it cradled him. Santino interacted with the same student with whom he engaged the other day during one part of our session as well. I intend to introduce it on our visual communication board if this is pre-planned in the future. After washing our hands towards the end of the session, I offered Santino a drink of water from a Styrofoam cup, and he drank from it twice when it was held to his lips. He pushed my hand away when he was done and lay down for a few minutes as I read him a book and we awaited his next teacher to arrive. Santino walked outside with me but was re-directed by his next teacher and returned to the classroom for his next class.
