  • Write the following numbers on the board: 0.56, 0.09, 0.75. Gather background information by asking students to place the numbers in order from least to greatest.
  • Have them work on their own using scrap paper. Observe their strategies (number line, converting to fractions, etc.) and whether they got the right answer.
  • Tell students to turn and talk to their partner about their chosen order. Monitor their language use and write some examples on the beginning section of the anchor chart Lesson Language. Make sure to note an example that needs improvement to ask students for their input later on in the lesson.
  • Choose a student to share the order aloud and have other students put their thumb up if they agree, thumb sideways if they're unsure, and thumb down if they disagree.
  • Tell students today they will compare only two decimals to determine which fraction is closer to 1.00.
