A fun way to teach language is to introduce similes to your class. I read my students the book, Crazy Like a Fox: A Simile Story by Loreen Leedy to introduce the concept of similes. This is a great book with cute illustrations.
Then, I gave each of my students a page with a simile and they illustrated the simile. I put all these together to make a book. My students loved to read their book in the reading center.
