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

  • Multiple examples help illustrate the main concept of rounding
Cons

  • The lesson title is not quite accurate, as it uses a combination of hundreds charts, base ten blocks, and addition to determine which direction to round
  • The video could do a better job of showing the correlation between the different-sized blocks and the number each represents; consider using this as a review lesson rather than an initial introduction to base ten blocks
