Classroom Considerations

  • If you aren't logged in to Learnzillion, you will be prompted to create a free account to access all materials for this resource
Pros

  • The explanation of skip counting is clearly communicated
Cons

  • The title implies that the lesson will discuss rounding, when in fact it simply means it will be focusing on time problems with one-minute intervals
  • The common mistake mentioned is not really a mistake, but rather a different strategy; discuss what extra steps would have to be taken to get to the right answer
  • While the description states that the lesson will focus on one-minute intervals, it actually combines skip counting by five with counting by one
