This article presents exploratory research investigating the way teachers integrate music into their
regular mathematics lessons as well as the effects of music-mathematics interdisciplinary lessons
on elementary school students’ mathematical abilities of modeling, strategy and application.
Two teachers and two classes of first grade and third grade students (n=46) participated in the
present study. The two teachers designed and implemented music activities as an integrated
part of their regular mathematics lessons across five weeks. Results demonstrated that both
teachers integrated a variety of music activities with different mathematical content. The musicmath
interdisciplinary lessons had positive effects on multiple mathematical ability areas.
