FRACTIONS: A MAJOR STUMBLING BLOCK
• Algebra: a Major Gatekeeper
• Problems: Often Not the Algebra
• Areas that Hinder: Lack of Understanding and Skills with Fractions (and integers)
• Often Taught Too Abstractly
• Music Can Help!

THEORETICAL FRAMEWORK:4E X 2 INSTRUCTIONAL MODEL

SIMPLE MEASURES IN 4|4 TIME
![Page 5: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/5.jpg)
CONNECTING MUSIC TO MATH
• Let’s “Sing” Their Durations
• How Might We Record the Durations of Each Note?
• Can We Use Addition for Each Measure?
• Can We Use a Single Fraction for Each Measure?
• How Can We Show Their Equivalence?
![Page 6: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/6.jpg)
LOOKING FOR EQUIVALENTS
• How many beats does a half note receive?
• How many quarter notes does it take to occupy that same number of beats?
• How many eighth notes does it take?
• How many sixteenth notes does it take?
• Express these equivalent relationships in mathematical symbols. Confirm your results.
![Page 7: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/7.jpg)
LOOKING FOR EQUIVALENTS (cont’d.)
• How many beats does a quarter note receive?
• How many eighth notes does it take to occupy that same number of beats?
• How many sixteenth notes?
• Express these relationships in mathematical symbols. Confirm your results.
![Page 8: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/8.jpg)
BUILDING TOWARD THE COMPLEX
• What fraction of a measure does a dotted quarter note occupy?
• What makes this type of fraction more “complex” than other fractions?
• How might we represent this using mathematical symbols?
![Page 9: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/9.jpg)
BUILDING TOWARD THE COMPLEX (cont’d.)
• How many eighth notes occupy the same number of beats as a dotted quarter note?
• How many sixteenth notes occupy the same number of beats as a dotted quarter note?
• How can you express these equivalent relationships mathematically? Confirm your results.

FINDING SUMSFind as many sets of notes as you can that are musically equivalent to 3 quarter notes. You can combine different types of notes in doing so. Use musical and mathematical notation to demonstrate your sets. Then, confirm your results.

RHYTHMS-FRACTIONS-MELODIES The following represents the rhythm of a phrase from a well-known song. Write the duration of each note in each measure in fractional form; then add them together to determine the time signature. Can you guess the song?

AND ONE MORE

EQUAL OR EQUIVALENT?
Name another fraction that is equivalent to . Why is some music written in 3|4 time while other music is written in a time signature that is different, but equivalent?

MUSIC: THE INFINITE MEASURE
• Our standard notes are the whole note, half note, quarter note, eighth note, and so on.
• Starting with the half note, write the first five note values in descending order using words, fractional notation, and musical notation.
• What is the ratio of the duration of consecutive notes?
![Page 16: NOTE BY NOTE; MEASURE BY MEASURE Mike Reiners Bob Horton.](https://reader036.fdocuments.us/reader036/viewer/2022062305/56649ca65503460f94968559/html5/thumbnails/16.jpg)
MUSIC: THE INFINITE MEASURE
• Write a partial measure in 4|4 time with:–A half and a quarter–A half, a quarter, and an eighth–A half, a quarter, an eighth, and a sixteenth–A half, quarter, eighth, sixteenth, and thirty-second
• Determine how many total beats are accounted for in each partial measure. Also indicate what fraction of the measure the notes occupy in total.
• What would it take for a full measure?

CLOSING THOUGHTS• Mathematics is everywhere!
• Context should be used to motivate students and help them learn. Music is one possibility.
• Start with the familiar and simple.
• Concepts BEFORE skills
• Explore BEFORE Explain (and let students explain)
