The video Exponents provides explanations and examples of solving problems and properties involving exponents; specifically The Product of Powers Property and the Power of a Power Property. After explaining and talking through examples, guided practice problems are given where there are built in pauses for the student to think and solve. After guided practice, self check problems are given; directions to stop the video and solve are given. Finally, the topics are reviewed. This video is well formatted and the narration is easy to follow. It can easily be used in a classroom setting or by individual students.
