Rounding and estimating are importa

Rounding and estimating are important numerical
thinking skills. Rounding expresses vital
information about a number without being unnecessarily
detailed. The number of passengers in the
airport could be expressed as “more than 1 million,”
“1.2 million,” or “nearly one and a quarter million.”
Rounding emphasizes the important information
without the less important details. Different people
might need more or less precision in a number. The
airport manager and board may need the detailed
information, but the citizens only need to know “a
little more than 1 million.”
