  • Write the words "What Do You Notice?" on the board, and underneath, display a series of numbers in which a specific digit has a different place value in each number. (e.g., 50,000, 5,000, 500, 50, 5)
  • Facilitate a think-pair-share based on the information on the board. Have students think about what they notice about the numbers, and then instruct them to turn and talk to a partner about their ideas. Call on students to share what they discussed with their partner. Provide a sentence stem to support student sharing. For example, "We noticed that ________."
  • Ask the following questions to further elicit discussion between partners and in the large group: "Which number would you want if the numbers represent apples and you have to choose a number that can feed the most people in your town or city? Why would you choose that number?"
  • Listen for students to reveal what they know about place value in their conversations.
  • Share a student-friendly language objective and have students repeat it aloud.
