Ohio educators, many of whom engage daily with Ohio students, drove the process to make improvements to Ohio’s Learning Standards for Mathematics as part of a periodic review. In many cases, the changes reflect instruction already taking place in Ohio’s classrooms. The clarifications in the revised standards will guide districts in modifying, not replacing their existing local curriculum, instructional plans and materials. In addition to the information available now, we will be providing additional resources to help educators learn about, and begin using, the revised standards.
