In This Unit of Study…

Fifth-grade students extend their understanding of place value by working with decimals to the thousandths place. Students at this grade have a deep understanding of place value and number sense, so they can explain and reason about rounded answers. Fifth-grade students round decimals to the nearest whole, tenth, and hundredths place. Students are expected to apply rounding while estimating an approximation and to determine the reasonableness of an answer.

B.E.S.T. Benchmarks:

  • MA.5.NSO.1.5 Round multi-digit numbers with decimals to the thousandths to the nearest hundredth, tenth or whole number.

Key Concepts:

  • I can use my understanding of place value to round decimals to any place up to the hundredths place.
  • I can use number lines and benchmark numbers to reason about rounding decimals.
  • I can explain how a decimal is rounded.
