This lesson was designed with the following in mind:
1. Students learn from their mistakes, and are more likely to master content when they can see and explain not only the correct way to solve a problem, but also the common misconceptions associated with the skill.
2. Mistakes are part of learning and "Catch the Error" lessons give teachers an opportunity to normalize mistakes, and name errors as a way for everyone to learn from one another in a deep and thoughtful way.
3. Ideally this lesson will be used as either a reteach or review. I typically use "Catch the Error" lessons when several students have made a common error on an assessment.
4. I begin "Catch the Error" lessons by giving students a few minutes to analyze the work from Student A and Student B and answer questions (1-3). We then begin a class discussion where I ask students questions (1-3) , always in the order shown. The discussion continues until the class is able to give the responses listed below. I then give students time to revise their answers to questions (1-3). We then move into a lesson centered around using the "Key Takeaway" that we learned was helpful in avoiding the error. The key takeaway becomes what I
monitor for as students complete related problems.
