This is a chart I made for Class Voice Levels. The Levels are described by Superheroes in certain situations.
Attached is a high quality file with the image. Also, I printed it out at Staples for about 10 bucks as a big poster for my room.
The Voice Levels from Highest to Lowest Are:
4 - Outside Voice (Picture of Superheroes playing sports)
3 - Teacher Voice (Picture of Superheroes at school listening)
2 - Table Talk (Picture of Superheroes at lunch)
1 - Sidekick Voice (Two superheroes as partners)
0 - Top Secret (Batman and Superman telling everyone to be quiet)
