Here is Voice Volume Scale 1
This scale is great for older students or those who get easily distracted by pictures. You can also use this after teaching the other scale(s) and see if the students can fill in the voice volumes. Younger students may also like to write and draw in their own pictures to match the levels.
I hope you can use this scale to help your students gain a greater understanding of voice volume.
Thanks So Much and Happy Teaching!
