If you've ever had the pleasure of reading The Phantom Tollbooth, you may remember the huge amount of word play and silliness with language. Puns galore! There are also quite a few examples of homophones, as a way for the author to make a clever little joke. For example, early on our young hero Milo meets a whether man. This man doesn't tell you the temperature or current conditions, but asks you whether you want this thing or that. A little later he meets an old woman named Faintly Macabre. She is a not-so-wicked Which. A Which is in charge of choosing which words were to be used for all occasions.
We spent some time thinking of other homophones, and I had some already listed on the board. Children were asked to use a pair of these words, use each word in a sentence, and illustrate their meaning. It was a fun exercise. Here is one example (and, of course, we could have added SENT to this).
