Introduction (5 minutes)

  • Ask students if they know what rounding is and how to do it.
  • Take volunteers to explain it in their own words. Define rounding as altering a number to make it less concise but more convenient.

  • Explain to students that you have a strategy for rounding to a given place value, too.
  • Review your strategy with students: Find the place, look next door, 5 or more raise the score, 4 or less let it rest, To the right: all zeros, all right!
  • Now use the strategy to round a few numbers chosen by you.
  • Leave the strategy on the board and have students copy it down in a journal or on a piece of paper.

Guided Practice/Interactive Modeling (10 minutes)
