Going on a Picnic
Students envision different groups of things and classify them into categories. They are told that they are going on a picnic and that they need to help you (teacher) get ready. Students are told that you want to pack three kinds of things: some food for lunch, some place settings so that they are able to eat their lunches easily, and some toys to play with outside after they have finished their lunches. They are shown an example of each item, and place it in the correct container.
