Here are 3 riddles I used last night for my students to guess on their way in to their lesson. I had planned to do something to test their skills, but in the end I decided to keep it 100% fun (after all, it is summer). Even if the students don't get them, the parents can have fun!
What kind of phone makes music?
What kind of band doesn't make music?
What kind of instrument is in your ear?
These are ones you've probably heard before; I found them at Just Riddles and More under the music category. I will say that I do not necessarily endorse all the jokes and riddles they have on the site- I actually have no idea what all is on there as I only browsed the music section. Use the site with discretion!
