Effective teachers think proactively when planning lessons.  Consider the particular students you will be working with, your time frame, the activities you’ve planned, the materials you are using and possible scenarios that may impact your plans; be prepared to adjust your instruction accordingly.  Describe the possible points in the lesson in which adjustments may need to occur and points in which instruction might be flexible in approach in response to student needs.  Prepare a plan to give more direct instruction or adapted instruction to students who may not be understanding the topic as well as a plan for increasing the rigor or difficulty of tasks when necessary.  Anticipate any behavioral challenges and create a proactive plan for managing classroom climate.  Consider the technology planned during the lesson and describe a backup plan should the technology fail.  Also consider pacing, teacher roles, grouping, assistive technology, and individualized student accommodations.
