The Louisiana mathematics standards were created by over one hundred Louisiana educators with input by thousands of parents and teachers from across the state. Educators envisioned what mathematically proficient students should know and be able to do to compete in our society and focused their efforts on creating standards that would allow them to do so. The new standards provide appropriate content for all grades or courses, maintain high expectations, and create a logical connection of content across and within grades. Students in Louisiana are ready for college or a career if they are able to meet college and workplace expectations without needing remediation in mathematics skills and concepts. The standards define what Louisiana students should know, understand, and be able to do mathematically and represent the steps students must take along the way to be able to meet this goal. The K-12 mathematics standards lay the foundation that allows students to become mathematically proficient by focusing on conceptual understanding, procedural skill and fluency, and application. This report addresses: (1) Development of K-12 Louisiana Student Standards for Mathematics; (2) The Role of Standards in Establishing Key Student Skills and Mathematical Proficiency; (3) Structure of the Standards; (4) Reading Standards and Interpreting Their Codes in Grades 3-8; (5) Reading Standards and Interpreting Their Codes in High School Courses; (6) Companion Documents for Teachers; and (7) Progressions in Math Standards. In addition to discussing standards for mathematical practice in Louisiana, the report presents standards for mathematical content by grade--Kindergarten-Grade 8; Algebra I; Geometry; and Algebra II. A list of resources including instructional materials resources, standards by domain, teachers companion documents, and remediation guides is also provided.
