I also combined some ideas from Pinterest and made this Circus Sensory Bin.
We targeted categories and yes/no questions during our play with the sensory bin. For students who are non-verbal, you can use simple yes/no switch buttons.
Our craft for the day was centered around yes/no questions as well. Every time the student answered the yes/no question correctly he was able to add a popcorn to the bag. We also incorporated the core word on into this activity.
If you have time the students can make their own elephant hat.
Finally, we built a bridge for the elephants to cross to get to the circus. The student was able to make requests, comment, and give directions during this activity using communication book. And as always, the real fun is in knocking the bridge down at the end and building it again.
