Without displaying the visual, ask students to two minutes to rehearse in their heads what each of the voice levels mean—how they would explain the meaning of each of the levels to a friend from another school.  After two minutes, ask individual students to explain the meaning of any of the voice levels, identifying first the voice level and then the meaning. For younger students, you may want to simply ask for meanings in order—from highest to lowest, providing think time in between each level.    

Ask for 3 or 4 volunteers. Have the group draw cards on which you’ve written numbers indicating each of the voice levels. The groups is then instructed to “perform” the indicated voice level while the rest of the class listens. Before the group performs, instruct the rest of the class that their job is to listen and write down the voice level that is being performed.
