Activity:
This activity will be used during a lesson on radicals and rational exponents. This would be a day two activity to solidify the concepts that were previously taught. The students would need to make sure that they were taking good notes during the video. The teacher would take the notes for a grade and then return them to the students so that they would have them to study. As the video is playing the teacher would need to stop the video during the problems so that the teacher can get feedback from the students to make sure that they are understanding the material.
At approximately 2:58 the teacher should stop the video and go over the table making sure that the students understand how the speaker is getting her answers. Resume video once all questions are answered.
At approximately 5:09 the teacher should stop the video and go over any questions that the students may have on the previous problems. Resume video once all questions are answered.
At approximately 6:12 the teacher should stop the video and go over any questions that the students may have on the previous problems. Resume video once all questions are answered.
At approximately 9:16 the teacher should stop the video and go over any questions that the students may have on the previous problems. Resume video once all questions are answered.
At approximately 13:14 the teacher should stop the video and go over any questions that the students may have on the previous problems. At this point there will be some video left, however, for this lesson, I would stop the video here and move on to the after activity.
Once the video is over the class would then play the game, "Did you know?". Each student would go around the room saying, "did you know..." and then following it with an observation from the video. The goal of the game is to get to the last person without repeating something already said.
After the game, the teacher would hand out the exit ticket, Rational Exponents. The exit ticket would be graded.
Assessment Strategies:
The student's notes would be examined to make sure the students had good material to study.
The teacher would assess the students during the video when she chose to stop the video and go over the problems. The teacher would also need to encourage proper listening and interaction by walking around the room and monitoring student behavior.
The teacher would also assess students' knowledge of the game and the exit ticket.
Advanced Preparation:
The teacher would need to watch the video before class to determine where to stop the video and decide what questions to use and what problems to model.
Variation Tips (optional):
The video could be used as a stand-alone lesson when the teacher has a substitute or wants to try a flipped classroom lesson.
Notes or Recommendations (optional):
This is a stand-alone activity, but also could be combined with the before and after activities below:
