High-Quality Curriculum Materials for Mathematics Rhode Island’s list of approved high-quality curricula in mathematics was published in advance of the 2023 selection and adoption requirement for LEAs outlined in RIGL§ 16.22.30-33. The intent of this published list is to provide LEAs with the ability to choose a high-quality curriculum that best fits the needs of its students, teachers, and community. Each LEA must choose a curriculum from the list for core mathematics. When possible, LEAs should adopt early because every student in Rhode Island deserves access to high-quality curriculum materials. The list is found in Appendix B of the guidance document Selecting and Implementing a High-Quality Curriculum in RI.
