  • Ask students to turn to a partner and discuss the term decimal. Listen in on student conversations and guide them to the discovery that a decimal is one way to show fractions or parts of a whole. On a piece of chart paper, take notes on their conversations and add a few examples of decimals.
  • Ask students when/where they have seen decimals in the real world and jot down students' responses on the chart paper as well. Validate students' ideas and add on any necessary points.
