Round to a Requested Large Place

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: Round 46,481 to the nearest thousand.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

Rounding a large number still compares neighboring multiples of the requested place. Find the lower and upper landmarks and the midpoint. A number’s many digits do not change the principle. This course uses the higher landmark for exact midpoint ties and labels the result as approximate.

Identify the stated place, bracket the number between neighboring multiples, and compare its distance to each. Round once from the original value rather than repeatedly rounding through smaller places, which can change the result.

Use the requested place’s midpoint. Repeated rounding can differ from rounding the original number directly. Write the lower landmark, midpoint, and upper landmark on a labeled number line.

1. Write the lower landmark, midpoint, and upper landmark on a labeled number line.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Identify the stated place, bracket the number between neighboring multiples, and compare its distance to each.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
