Reflection:

 

Although the source of the video is not Khan Academy which is everyone's go to source when it comes to math, this video is still helpful in learning standard 8.EE.7 because the video is clear and precise and breaks everything you must know in order to master this standard. The video is slow because it reviews concepts multiple times in the video, but that's okay, because all that matters is that you get the point of the standard and also that you're having fun!
