The document provides instructions for rounding numbers to the nearest ten, hundred, or thousand using place value. It explains that to round, you identify the place value being rounded to, underline the number in that place and everything before it, then consider the number after to determine if the underlined portion should round up or stay the same based on whether it is closer to the next highest or next lowest multiple of the place value being rounded to. Several examples are provided rounding numbers to the nearest ten, hundred, and thousand.
