Teacher Resources
Teaching Notes

Emphasize focusing on the tens digit to decide whether to round up or down. Use a number line to visualize how numbers fall between hundreds.

Vocabulary
Round: To estimate a number to a certain place value.
Nearest Hundred: Closest multiple of 100.
Common Mistakes
  • Looking at the hundreds digit instead of the tens digit.
  • Rounding down when the tens digit is 5.
  • Incorrectly identifying the 'nearest' hundred (e.g., 349 to 400).
Differentiation
SupportUse a physical or digital number line to illustrate the rounding process.
ChallengeDiscuss how rounding is used for quick mental estimation in real-world scenarios.
Discussion Questions
  • How does the tens digit help us decide whether to round up or down?
  • When might you use rounding to the nearest hundred in everyday life?
  • Can two different 3-digit numbers round to the same hundred? Give an example.
  • If a number has 0 in the tens place, what happens when you round to the nearest hundred?
