I am definitely incorporating a quiet corner in my classroom. I think Torey had it right and when students are getting too upset and jumpy, they need to have a place that's designated for them to calm down and be ready to work again.
New Year's Resolutions Foldable - Great activity to use before or after winter break to discuss goal setting with students! 3 versions of the foldable included, along with a short writing prompt, and bookmarks!
Easy No Sew Chair Pockets made from pillow cases~ Love this free make-it-yourself idea! Handy place to keep a few favorite books within easy reach for each student. (An extra pillowcase is something many parents have and are happy to donate.)
