I also got some "hot lips" clips for working on bilabial sounds.
The Octopus hanger is my ALL TIME favorite for Articulation Drills. I hang it on a long string in my therapy room. The children have to say the card a certain number of times before the Octopus will "eat" their card. Then they have to say each card again (maybe in a sentence) as they take the cards down at the end of the activity. I got the Octopus hanger at Ikea last year for under 10.00. Well worth the money.
