The Texas Education Agency is pleased to announce the availability of state-developed, open-source instructional materials, which are provided to districts free of charge.

The materials in this resource were created by Rice University's OpenStax. They are organized into units and chapters and can be used like a traditional textbook as the entire syllabus for each course. Individual lessons and units can also be accessed for supplemental use. Request teacher materials and other ancillaries for OpenStax products by emailing open-sourceinstructionalmaterials@tea.texas.gov from your school email address.
