You may already do this, but I:
1) have the students point to where the word goes and we put it up together
2) play one game a week that requires cross-referencing. I feel that these games are what REALLY affects my student's abilities to find a word. From playing them, they not only know what general vicinity every word is in, but also if a word is a word wall word or not on first glance.
My favorite one is Mystery Word. Kids number their paper or white board #1-5. The first clue is always: It's on the word wall. They write any word. NO ERASERS! The 2-4 clues are always stuff like: it's between A and F, it has a basement letter in it, it has 2 vowels, it is a noun, it fits this shape (draw shape of word on board), it has more than 3 letters, etc.... When the last clue is ready to be given, it is always down to about 3 or 4 words it could be. The last clue is always, "It fits in this sentence: _______" I attribute all my kid's success with the word wall to this game!
