Find 10 things, living or nonliving, that have some similarities and design a key for the 10 things with a partner. test the effectiveness of the key by giving the key and the objects to another group in the class and see if they can follow through with the proper identification of the objects.

Here are some ideas:

  • 10 Arthropods, live or pictures

  • Cut out 10 different shapes from a piece of paper

  • 10 different leaves from trees

  • 10 flowers

  • 10 pieces of fruit

  • 10 nuts
