Give some examples of how math is connected to music.

- When might a musician use counting?
- Can the volume of an instrument change its sound?
- If you know how to read music, how are notes measured?

- Listen to the music as a class and tap out the beat with your classmates.

AUDIO: Beats

Open the interactive and play one of the sound tracks. Follow the instructions and tap the beat as you listen to the songs.

After listening to a track, discuss these questions with your partner.

- Is the number of beats per minute constant? How do you know?
- How are the beats expressed on the double number line?
- Choose the graph option. How are the beats expressed on the graph?
- Compare the graph and the double number line. How are they alike? How are they different?
- Play another track and verify your findings about the questions.

INTERACTIVE: Tap the Beats

Think about what a point on the graph means.

Take notes on the beats per minute and how they are represented on the double number line and the graph.

- What is meant by
*constant rate*? - How does your double number line show beats per minute as a constant rate?
- How does your graph show beats per minute as a constant rate?
