Why is it sound teaching practice for a teacher to begin with the end in mind and to share her lesson objectives or intended learning outcomes?

Beginning with the end in mind helps the teacher set clear goals and stay focused on what students should achieve by the end of the lesson. Sharing lesson objectives or intended learning outcomes clarifies expectations for students, helps them understand the purpose of the lesson, and provides a roadmap for their learning. This approach promotes student engagement, motivation, and accountability in achieving the desired learning outcomes.
