  • Checks for understanding move beyond traditional multiple choice; kids manipulate graphs to solve a problem.
  • The Community Question section encourages kids to teach each other.
  • Some videos like “Introduction to conic sections” could use better organization.
  • The video, “Trolls, Tolls, and Systems of Equations” presents a creative way to introduce this concept.

How Can Teachers Use It?

Khan Academy's Algebra 2 content might be best used as solid, at-home practice to support kids who struggle. The tutorials and instructional videos are clearly labeled with the topics commonly used in Algebra 2 classrooms. As with much of the site, the videos have a spur-of-the-moment feel. Some kids might enjoy the spontaneity of Sal's conversational tone, and it's probably best utilized to liven up at-home practice and review. However, many videos lack the organization expected of a well-articulated in-class lesson. Whether you're using the Missions or pointing students directly to specific tutorials, be sure to carefully screen content beforehand to make sure it aligns with your in-class instruction.

If using the Algebra 2 Mission, students will enjoy moving through the curriculum at their own pace as well as the immediate feedback on quizzes. This can be helpful for kids who need to catch up with a lot of material over a short time. Advanced students may not find the problems challenging enough; nevertheless, this could be useful practice for those looking to test out of the class. Advanced students could also go to the Community Questions section and earn badges by answering other students’ questions.
