Teaching "What's this/that?" in a very different way!

These days I found a great idea in one of the books I use for teaching kids at my mini school. I'd never thought of that before but I got to the conclusion it could be a wonderful way to get my students involved with the content I had to teach. The subject was "What's this/that?" and its corresponding questions and answers such as "Is it a book?", "Yes, it is" or "No, it isn't". Guess what! All we need to use is play dough! Yes! Play dough in the classroom! So I bought it and this afternoon I had the chance to try the activity shown by the book. It was great! Kids love playing with different kinds of material in class so I asked them to create something using play dough about the vocabulary we've just learned. For example: school material, just like: pen, pencil, pencil case, etc. So students had to keep asking each other in order to guess what they were creating. Student A asked Student B: "Is it a crayon?" and the other one would say: "Yes, it is" or "No, it isn't" and so on. Notice that we can work on not only on the structure of questions and answers but also vocabulary. Reeeeally nice! See you, colleague!
