Essential Understandings

Concrete:

  • Make a set of base ten blocks that represents a three-digit number that is multiple of 100.

  • Recount the set to get a sum or difference.
Representation:
  • Make a visual representation of base ten blocks that represents a three-digit number that is multiple of 100.
  • Add or take away a visual representation of another set of base ten blocks that represents 100.
  • Recount the set to get a sum or difference.
  • Use a thousands chart to count forwards or backwards by 100’s from any given three-digit number that is a multiple of 100.
