What a lovely story I came across during the month of Apri;, Elmer the Elephant by D. Mckee. It was an easy conversation starter about differences and similarities. The first thing we talked about was our differences and if we are happy that we are different from each other. We also talked about how I am different from everyone else in the classroom and why. The kids learnt that being themselves was very important. Here is a reading of "Elmer" in English from youtube.
