Learning Goals specify the learning that is intended for a lesson. Learning goals are usually restricted to a single lesson and may refer to understanding (i.e. a portion of the Lesson Objective), knowledge, skills, or applications. They may also reference a process for doing math such as the Standards for Math Practice, or behaviors such as modeling quality collaboration. These goals may use words such as know, develop, become fluent, apply, understand, use, or extend. They are often accompanied by success criteria. They can also be identified by their function: concept goals, process goals, or product goals.
