Khan's 8th Grade Math content is best used as a support for good classroom instruction. In class, it's best for kids of this age to learn socially, with both peers and teachers. As such, Khan's best use here may be at home, where kids can sometimes get stuck. Using content from the 8th Grade Mission, you can further personalize kids' at-home work.

With that said, if you're targeting some more specific eighth-grade skills in class, you might want to use some of the tutorials in your daily instruction and activities. Using your dashboard, you can identify points of struggle, either for individual students or your whole class, to help target your reteaching efforts. This may be particularly helpful in classrooms where students have a broad range of abilities. These tools for differentiation can make it easier to provide all your students -- those struggling as well as those more advanced -- the tools they'll need to thrive in next year's high school math classes.


  • Recognizing Rational and Irrational Numbers: Watch a video comparing these two types of numbers; drag and drop examples to see if you understand the difference.
  • Angles Formed by Parallel Lines and Transversals: Although a bit rough, this video guides viewers through the concept. Be patient –- while the ideas are accurate, it may take a while to get to the point. Note: While the standard, and the site's checks for understanding, refer to angles as "congruent," the video uses different vocabulary.

Full Disclosure: Khan Academy and Common Sense Education share funders; however, those relationships do not impact Common Sense Education's editorial independence and this learning rating.
