Everyone had their sound on and I had to frequently tell students to turn the volume down. Our students are now able to focus on their individual math lessons without being distracted by other student's computer sounds. I also have a student who does not speak proficient English, and he is now able to use the headphones to help him read in Spanish. Students are also able to use their headphones during online tests. We love our headphones!

As a teacher I do not have the added stress of creating lesson plans with very limited materials, which then limits the creative process and the limits the opportunities for my students to explore. 2. The zeal my students have to create and explore is even more potent. Some of my students have never painted not only can practice with paint but with paint sticks, water colors and mice paper.
