Do your same goals - but, do them with actions. Throw a beach ball to them after they say their sounds. Borrow some of those floor scooters from PE or the PT...and have them scurry around to get pictures. Make a no-bake recipe...but they have to work to get the items for the next step. Use watercolors or the white board to paint pictures for vocabulary... or idioms ... or opposites, etc. Have a scavenger hunt in your room or on campus for items per artic. sound. Provide a piece of a floor puzzle per participation. Shoot a video. Make a commercial for a product ...using language goals or speech sounds or fluency or voice skills.
...I feel the same as you do! I think I'll "shake things up" a bit more, tomorrow!
