In 2006 the Ohio Department of Education (ODE) submitted and received a three-year Foreign Language Assistance Program grant from the U.S. Department of Education to write and pilot a K-4 content-enriched Mandarin curriculum and to build online professional development modules to support the curriculum. Once funded, ODE formed an advisory committee to reach consensus on a curriculum template and to provide guidance on literacy development. In this article, the author presents unit descriptions and performance outcomes of the K-4 Mandarin curriculum. Teachers affirmed students' enjoyment of learning Mandarin Chinese through these units.
