This is an assessment I used during student teaching. I used this for a lesson I was giving on instrument identification. I played samples of music for the children, and they circled the instrument that they heard. I used YouTube videos during the lesson so the kids could see people playing the instruments. During the exam, I only used the audio so they heard the same things from their lesson.
I have a Powerpoint that I used along with this, but I am currently reconstructing it because it was made very specifically for my class.
