Are you tired of reading "happy", "sad", "big", "small", etc. over and over again in your students' writings? I came up with a list 11 most common overused words from students and included several good synonyms they can use instead.
I plan to use library card holders on a poster and have the synonyms on card stock tucked inside. I have an example picture on the last page. The photo is from: http://teachlaughlove.blogspot.com/2011/07/tired-words.html
DISCLAIMER: This was made for the intention of 3-5. This could definitely be modified for younger and older grades.
