I learned about graffiti walls from my student teacher. It is a simple way to help students understand concepts. To create a graffiti wall you will need a piece of paper. In the center of the paper, draw a circle or any shape. I like to do a squiggly cloud shape. Write the concept in the center of the shape and everything that has to do with that concept. On the outside of the shape, have the students write everything that the concept is NOT.
My students and I created a graffiti wall bulletin board on vivid verbs. We added as many vivid verbs to the center. Some verbs we came up with are scampered, casting, stroll, animate, devoured. On the outside of our wall we placed helping verbs, conjunctions, linking verbs, nouns, adverbs, adjectives. Students were then allowed and encouraged to add to the graffiti wall whenever they heard of an excellent vivid verb.
I also tweaked this idea by creating a huge idea wall for my students at writing camp this week. I used a huge piece of butcher paper and across the top I placed the headings onomatopoeia, instead of said, adjectives, adverbs, and vivid verbs. I wrote words under each category to start the brainstorming process. When I introduced the wall to my group on Monday, I had them brainstorm aloud and I added words under the category. Throughout this week my students have added words to the wall and have used the words in their writing, which was the goal!
