Lesson planning is a teacher's guide for what students need to learn, how it will be taught, and how learning will be measured. It helps teachers be more effective by providing a detailed outline to follow. Good lesson planning is essential for teaching and learning as it allows teachers to thoughtfully plan objectives, activities, sequencing, materials, timing, and grouping. A detailed lesson plan has five parts - objectives, subject matter, procedure, evaluation, and assignment. The first step in any lesson is effective lesson planning, which includes knowing your students, setting learning objectives, writing the lesson objective, and planning your timeline.
