I do a few thing for vocab.
1) Flash cards: These can be used as a "memory" game. Students draw a simple picture or symbol for the word that defines it. Then, they match them up with a partner in a game like Memory.
2) Act them out. "Who can show me 'rambunctious?'" "Can you do it differently?" "Who can show me the opposite (or antonym)?"
3) A chart with the following columns: Word, Dictionary, Mine, Sentence, picture, Synonym, Antonym. You can pick and choose which ones you want, but turn the paper landscape and make boxes about 1" so they have room to work. I can post it I think... just let me know if you want to see it.
4) I make a note in my plans reminding me to use the word during the next few lessons. "So, that cat was kinda crazy, wasn't it? I'd say it was a bit ... RAMBUNCTIOUS, wouldn't you?"
5) When we reread, I have them put a finger on their nose or do deaf applause when they hear one of our vocab words in the text. Sometimes I forget and have to think about why they are doing deaf applause....

Let me know if this is helpful or if you have any further questions.
