I display these on my writing wall so the students can refer to them when writing. I use these charts as an introduction to using an actual thesaurus.
They are also great ways to introduce new vocabulary.
I used Woodland, Camping, and Forest graphics on a striped, polka dotted, or chevron background, so I could incorporate all of these into my classroom.
I print them 2 or 4 to a page, because of the amount of space I have on my walls.
