Ahead of time set the classroom up so there is a box and then a workstation after it. Lay the boxes on their sides so the students can come up and put their hands in the cut out holes. Place one item in each box (one box will have oranges; one will have crayons, etc) and close the flaps. Talk about the five senses: sight, touch, taste, hearing, and smell. Explain that today the students are going to have to use two of those senses, touch and smell, to try to identify some items you have placed in the boxes
