This might seem elementary.but I love the quiet spray idea! Very cool teacher ideas on this site. Quiet spray has nothing in the bottle but air. This may be the smartest classroom management tool I have ever seen.
The author posted this great idea of a calming caddy. It is filled with different sensory objects to help students calm down when getting frustrated. She includes things such as stress balls, calming glitter jar, play dough and notebook and crayons.
