The document describes 10 models for integrating curriculum in K-12 education. The models range from teaching individual subjects separately (the fragmented model) to fully integrating subjects around themes (the integrated model). The 10 models include: fragmented, connected, nested, sequenced, shared, webbed, threaded, integrated, immersed, and networked. They provide teachers with a continuum of options for designing curriculums that help students make connections across different subject areas.
