How to approach rounding numbers

Rounding replaces a number with a nearby benchmark at a chosen place. Find the rounding digit, inspect the digit immediately to its right, and then replace all following digits with zeros.

A right-hand digit of 5 or more increases the rounding digit by one; 4 or less leaves it unchanged. Number lines can show which benchmark is nearer.

Learning objectives

  • Round to tens, hundreds, and thousands
  • Identify the rounding and deciding digits
  • Estimate using rounded values

Skills to review first

  • Place value
  • Comparing distances
  • Counting by tens and hundreds
Worked example

Follow the reasoning step by step

  2. Look one place right at the tens digit, 4.
  3. Because 4 is less than 5, keep the 6.
  4. Replace the tens and ones digits with zeros.

Solution: 3,600.
