This is a PowerPoint Presentation that starts with a review of the instruments of the orchestra. It discusses what instruments are in the Instrument Families and how each Instrument Family makes sound.
Then there's a "Pop Quiz" with animated slides, where a question pops up, and then the answer pops up.
Then, there is a Jeopardy Game that allows the students to work in groups as teams to review what they've learned. (I've found that having five teams works best.) This allows you to Assess what they've learned.
I usually go through the PowerPoint with them, and then the "Pop Quiz" one day, and then review the PowerPoint the next time that I see the class and have them play the Jeopardy game after the review.
