Quotes to put up around your classroom. I print them out on brightly colored paper and laminate. I've had them around the top of my room for years!
1 quote per page, easy to laminate and put up! No editing required!
They are a mix of motivational, environmental, and a wide variety of sources.
Also, a nice one to remind whomever may pop in your room:
"Not everything that counts can be counted, and not everything that can be counted counts."
