This chapter explores the main issues to be considered when planning long-term units and daily lesson plans. It discusses how veteran teachers “lesson image” instead of lesson plan. A good lesson plan sketches out a beginning point and an objective or list of objectives for the class period as well as a set of instructions for how to get a class to where the teacher wants it to go. Instead of the teacher telling students what they were supposed to know, student opinions and questions were valued and used to redirect the instruction. The lesson procedure, a set of instructions for the teacher, is the heart of the lesson plan. The extension component of a lesson plan is an activity that provides the teacher with an option if students catch on more quickly than anticipated or are in need of an additional challenge.
