Instructor Overview

In this lesson, students are introduced to rate in the context of music. They will explore beats per minute and compare rates using mathematical representations including graphs and double number lines.

Key Concepts

Beats per minute is a rate. Musicians often count the number of beats per measure to determine the tempo of a song. A fast tempo produces music that seems to be racing, whereas a slow tempo results in music that is more relaxing. When graphed, sets with more beats per minute have smaller intervals on the double number line and steeper lines on the graph.

Goals and Learning Objectives

  • Investigate rate in music.
  • Find beats per minute by counting beats in music.
  • Represent beats per minute on a double number line and a graph.
