During the interview, the interviewer may ask you about a lesson that went well and why for a few reasons. First, they want to know about your teaching style and how you approach lesson planning. Additionally, they want to see how you handle challenges and obstacles in the classroom. By understanding what has worked well for you in the past, they can gauge how you may handle similar situations in the future. It's an excellent opportunity to showcase your strengths and demonstrate your ability to adapt and problem-solve. Be prepared to share a lesson that you're proud of and explain why it was successful. However, a successful lesson doesn't necessarily have to achieve any math goal. Sometimes, a good lesson can go well because the students are happy or feel accomplished. There's no correct answer to this question, as your response is based on personal experience.
