I used an old Kleenex box and covered it with duck tape. You can use whatever for the counting. I used cotton balls (20) and then when a student is starting to throw a fit or having a hard time following directions you have them dump out the 20 items and count them as they put it back in box until they calm down!!
The Worry Box. Perfect for kiddos experiencing anxiety and stress that is negatively affecting their daily functioning. By writing the worry down and enclosing it in the box, kids can tangibly "remove" their worries...hopefully leading to better sleep, easier mornings, and academic/social success.
-- link goes to a store -- but these would be great to have kids (and adults) put around their neck and then explore how negative self talk/worry/perfectionism, etc. is like having this thing on your shoulders all the time.
