Fractions Curriculum Strikes Right Note In California A music-focused math program in the San Francisco Bay Area is showing significant results. Third graders in San Bruno, Calif., who took two 30-minute music classes better understood fractions than those who did not follow the curriculum.

Math teachers know that fractions can be hard for the average third grader. Teachers at a public school in San Bruno, California, are trying something new. They're teaching difficult math concepts through music. As Caitlin Esch reports, they're getting results.

ENDRE BALOGH: Pick up the drumsticks. One, two, ready, go.


CAITLIN ESCH, BYLINE: At Allen Elementary School, a roomful of third graders sits facing music instructor Endre Balogh, their backs straight, eyes ahead, beating a mouse pad with drum sticks.


ESCH: These students are learning fractions. Nine-year old Donte Arevalo explains.

DONTE AREVALO: Two-eighths plus six-eighths, you have eight-eighths. But since it's in the music, it equals a whole note.

ESCH: The program is called Academic Music, and it works like this. First, students learn the basics of reading notes. Then, they learn how to add notes, which is essentially adding fractions. Now, Balogh is drawing the music notes on a board and adding them together.

BALOGH: What should I write on the top here? How many eighth notes do you see?


BALOGH: Good job. Now, I wonder what should I write here because this is tricky?



ESCH: From there, it gets harder. Students learn to how add uncommon denominators and multiply fractions. San Francisco State University researcher Susan Courey designed the curriculum with Balogh in 2007 because as a former third grade teacher she knows how tricky fractions can be.

SUSAN COUREY: If you say, what's bigger, one-eighth or one-fourth, they'll say one-eighth, because eight is bigger than four.

ESCH: Courey says it's all about visualization.

But our students - because of the notes - know that all those little tiny eighth notes are a lot smaller than a whole note or a half note.

BALOGH: Ready? Play.


ESCH: In this class, more than half the students are English language learners. Classroom teacher Gina Grites says Academic Music has especially helped her students, like a little girl who volunteers to solve a problem, even though she barely speaks English.

GINA GRITES: And she knew that it was four counts and put it into a fraction. And just to have her get up and present in front of a class is a really big deal, and she raised her hand and wanted to. So I'm seeing a lot of these kids open up and want to try it, instead of hiding behind the desk and saying, please don't call on me.

ESCH: A recent study found students that went through the program tested better on fractions. The average score of the Academic Music students was nearly double that of the regular math class students. Curriculum creator Susan Courey says even low-performing students did better.

GRITES: That's what I, as a classroom teacher, want. I want to know that those students who typically are the underachievers are benefitting from the instruction that I'm providing.

In a less formal study, Allen Elementary School teachers compared their kids' math scores with third graders in other district schools. Again, Allen students performed better.


ESCH: Back in the classroom, 9-year-old Eric Bogren says he'd never played an instrument before Academic Music.

ERIC BOGREN: It's really easy when it's music, but it's harder to do it when you're doing math.

ESCH: For Bogren, thinking of fractions as music notes helps. The curriculum designers hope to eventually make the program available for any third grade teacher to use in the classroom. For NPR News, I'm Caitlin Esch.
