This scenario is assessed:
It is the third month of the new school year and you have just finished a week-long unit of study that covered key grade-level standards for your students. Prior to teaching the unit, you invested significant time and effort into preparing lessons, activities, and supporting materials. However, over 50% of your students failed the end-of-unit test you administered at the end of the week. To keep up with the pacing calendar, you are expected to move on to a new topic the following week.
Describe what next steps you would take to address this situation.
As you describe what next steps you would take to address this situation and still move with your pacing guide, I'd recommend taking each weak/failed standard and place it as bell work or starter work each day on your white board, overhead, ...
Problems with standards are brainstormed using a case study method. This solution also suggests various strategies to align with the pacing guide.
