I love whisper phones. They help students hear their voice amplified in their own ear. They can help students focus in on certain sounds. They can help with reading fluency, because the student can hear the sound and cadence of their voice in their ear. I also love using them to work on expression. Students are really able to hear the differences between questions, statements, and exclamations.
I know that it is super easy to make your own whisper phones, but I am a little lazy about some things. I wanted one that I could buy and use. I previously wrote about how I love the hardware store and p traps in particular. You can see that post here.
There are two types of p traps that I use. I use the one with a removable drain spout for addition and one without for whisper phones.
Here are the two p traps that I use. A small one for the kids and the “big momma” for me! There may be different sizes than these two, but these were the ones that worked best for me.
