Lesson Plan (Grades 3-5): Math in Music - A Comprehensive Grades 3–5 Fractions & Rhythm Unit

Explore fractions through rhythm in Math in Music for Grades 3–5—map note values to fractional beats, clap and notate patterns, compose 4/4 measures, prove equivalencies (eighths, quarters, dotted notes), and connect math equations to real musical performance across five sessions.

I. Introduction

Lesson Title: Math in Music

Grade Level: Grades 3–5

Subject Area: Mathematics (Fractions) & Music

Overview Beats and fractions go hand in hand. In this five-session unit, students will discover how musical rhythms correspond to fraction values, compose their own rhythms, and notate them using standard symbols and fractional labels. Students will:

  1. Feel the Beat: Internalize a steady pulse at a comfortable tempo (60 BPM).
  2. Map Note Values to Fractions: Connect whole notes, half notes, quarter notes, and eighth notes to fractional parts of a 4-beat measure.
  3. Perform Rhythms: Clap, drum, or tap rhythms accurately, counting beats and subdividing when necessary.
  4. Compose Measures: Create and notate four-beat measures using a variety of note values, including dotted notes and rests.
  5. Analyze Equivalencies: Demonstrate that two eighth notes equal one quarter, that a dotted quarter equals one and a half beats, and more.
  6. Integrate Notation and Math: Write fraction equations corresponding to each composed measure, ensuring the sum equals four beats (4/4).
  7. Apply to Repertoire: Transcribe and perform rhythms from familiar tunes and explore compound meters.

This unit builds conceptual understanding of fractions through kinesthetic and auditory experiences, reinforces fine-motor skills through notation, and highlights real-world applications of mathematics in the arts.


II. Objectives and Standards

Learning Objectives Students will be able to:

  1. Identify the fractional beat value of whole notes (4/4), half notes (2/4), quarter notes (1/4), eighth notes (1/8), and dotted notes (3/8, 3/4).
  2. Accurately perform rhythmic patterns by clapping, drumming, or tapping while counting beats aloud.
  3. Compose and notate original four-beat measures using a mix of note values and rests, clearly labeling fractional durations.
  4. Calculate the sum of fractional beat values in each measure to confirm a total of 1 whole (4/4) measure.
  5. Demonstrate equivalencies, such as two eighth notes = one quarter note, two quarter notes = one half note, and dotted notes’ fractional relationships.
  6. Analyze and transcribe the rhythmic patterns of simple songs, connecting notation to sound.
  7. Reflect on how mathematical thinking informs musical composition and performance.
