Pros

  • Examples of solving the same problem in multiple ways allow many opportunities for understanding the concept
  • The video clearly describes the common procedural mistake seen in this type of multiplication and explains why it is a mistake
Cons

  • While the title mentions commutative and associative properties, these terms are not used in the video, so be sure to share this academic vocabulary with the class either before or after watching
  • Similarly, the word diagram is used but never defined, so be sure learners are familiar with what this word means
