Piano students should learn about music as a whole. One way to learn about the broader musical world is to quiz students on musical instruments. I created this quiz sheet by copying and pasting images from the internet onto a blank document. After coloring the instruments I laminated the sheet. The quizzing usually takes less than one minute or two, and students simply name the instruments from the page. A variation of the quiz could be to play clips from certain musical instruments and to have students say which instrument is being featured (ex. playing a clip of a violin).
