• Forgetting to zero out digits after the rounding place

Differentiation

Discussion Questions

• What does the thousands digit tell you?
• When does rounding change the hundred-thousands place?
• When is rounding to the nearest 10,000 useful in real life?
• How does the thousands digit determine the rounding direction?
• What if the thousands digit is exactly 5?
• How is this skill connected to place value understanding?

Extension Activities

• Round distances/populations
• Design two numbers that round to 90,000

Parent Tip

Discuss rounding large numbers like populations of states or countries.
