Khan Academy's Algebra 1 content might best be used to help kids check their understanding once you've already covered a topic in class. The quizzes at the end of each tutorial can be used for homework or as an in-class formative assessment. Kids can use the Missions to reinforce foundational skills or work ahead. However, take note: Some of the instructional videos here are a bit slow-paced. Kids could get bored or distracted as Sal backtracks, reorganizing the way he writes FOIL, or during his discussion of why he doesn't like this method. As a comparison, Virtual Nerd's tutorial on FOIL covers the same topic much more succinctly. That said, Khan teaches the concept correctly, presenting the distributive property as an alternative to this method. It would just be better if it were clearer and more precise.

On the flip side, the fact that Sal takes time to emphasize the nature of mathematics is a great benefit. For example, the video "Descartes and Cartesian coordinates" highlights the importance of persevering through math problems; this would be an excellent video to watch and discuss as a whole class. For another cool activity, in “Understanding the process for solving quadratic equations,” kids are asked to look for flaws in a sample student’s work. This kind of exercise can help students become more metacognitive about their own mathematical processes.

Khan Academy is great for individualized learning and students who work independently.

Khan Academy is designed to be work well for individual student instruction. The mathematical instruction is sound and the individual pacing of the lessons allows students to progress and review at their own speed. This is an especially effective way to teach a group of students whose mathematical needs are diverse.
