Objective: To introduce fractions as they occur in music. To demonstrate the common use of mathematics in other curriculum.
Materials:
Required: The below Youtube video, chalkboard & chalk or pencil and paper
Optional: Metronome, Sheet music of Old Time Rock & Roll, piano
Steps:
1. Introduce to the class the concept of fractions and how common they are in daily life.
2. Play the video the first time. If a piano, sheet music and sufficient piano skill (or the music teacher), play the music the first time on the piano.
3. Draw the first line of music on the board or paper. If the sheet music is available, distribute a copy of the first line or project on an overhead.
4. Set the Metronome to the tempo of Old Time Rock & Roll (I believe 4/4 time)or have one half of the class keep the beat.
5. Have the other portion of the class, tap to the rhythm of the music as a counter. Repeat 2-3 times.
6. Demonstrate how a bar is broken up into 4 beats. Show how the notes are written as whole, half, quarter and eight notes. Demonstrate the fractional equivalent to show how the same notes are represented in math terms.
7. Get ready for an excited class looking to you pointing out more such similarities to prove how math is relevant.
