What activity/game can I do for my vocabulary word?

Why not try a pictoword. This is where you use the letters in the word to illustrate the meaning. Simple examples would be to draw running feet on the letters of run. Make eyes out of the e's in see. It can be challenging, but very creative. Have some examples of other words that you have made pictowords out of, cause if you show them an example using advocate, then you will get mostly copies of your word. Give them each a piece of printer paper and then cut them loose with their creativity. Good luck.
