Language
Students will be able to explain the value of digits in a number and how to round to the nearest 10 or 100 using discussion supports and sentence stems.
Introduction
(5 minutes)
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.
