Students can work individually, in pairs, or larger teams. Have students number from 1- 25 on a piece of paper.
From a box, teacher places on a table an object that serves as a clue for a mastery reference. A new object is placed on the table every 30 seconds. Students write the object and the reference on their worksheet. Each of the 25 SM is used ONCE.
When all 25 objects are on the table, students get 10 minutes to figure it all out. At the end of 10 minutes, the teacher bellows STOP! One object at a time, the teacher guides the class to the correct answer.
