I work on an elementary campus (K-4) in north Texas with an enrollment of around 460 students. I am fortunate that I have a large office space with areas for small groups, individual sessions, a calm down corner, and room for activities on the floor. I will share where I bought items (if I can remember). Please note that I am not an affiliate of any of these companies just sharing my office space with you.
When students first enter my office they sign in using a flower pen. This dresser I bought from Facebook Marketplace for $40 and it sits near my Calm Corner. I turn on the music and set the little blue timer when students need a few minutes to gather their thoughts or calm their emotions.
Here is my Calm Corner. There are calm down toys inside the baskets in the dresser and a lamp when I turn the lights down. I was lucky to find this chair for $10 from Facebook Marketplace. Facebook Marketplace is a goldmine for counselors and teachers. #TrashtoTreasure
I have two bookshelves on opposite sides of the room. I took the same material from the curtains and hot-glued it to the doors of the upper shelves. One is used for game storage and the other holds books that are easily accessible for my students.
As I mentioned earlier, I'm blessed to have such a large office space where students feel comfortable and have a variety of activities and areas to enjoy the Counselor's Office.
