Students will learn all the key principles of classification as they work with the hands-on materials in this kit. Common nuts, bolts and screws are the objects to be classified! Students will be guided step by step as they develop their own dichotomous key for the collection of fasteners. When the keys have been written, the fun begins as students exchange their keys and objects. The principles of classification become obvious immediately. A perfect hands-on, introductory classification activity. Includes teaching suggestions and student materials.

Super Value Kit is complete for 30 students working in pairs. All materials are reusable.
