Word of the Week "title" for a bulletin board.
Since I am a related arts teacher this year, I don't have enough time to incorporate small groups during my time with the children. However, I have used something similar in the past - Small groups could rotate the room, and this could be a station to stop at. The children could write their guesses about the word's definition, or use the word in a sentence after looking up the definition --- endless possibilities!
This board could be used during a novel study working on vocabulary from the novel.
