This is a fun activity. You will need a big box with two round holes two holes cut in it - big enough for your students to put their arms in. Get everyone to close their eyes as you put a toy in the upturned box. Model first: put your arms through the holes and feel the toy. Pull a face to show you are feeling something and don't know what it is. Then finally, look happy and say "It's a puppet!" and lift up the box to show everyone what you have found.

Let each student have a go. Also, a great idea is to also add some other objects that students have studied in a previous lesson (e.g. a crayon, plastic fruit, plastic animals, etc.) - this will add an element of surprise and allow for vocab review.
