Students will be able to write three-digit numbers using number names.
Students will be able to explain how to write three-digit number names with content-specific vocabulary using sentence frames and partnerships for support.
Create a table on the whiteboard with two columns and two rows (four squares total).
Write one of the following numbers in each square: 375, 258, 361, and two hundred eighty six.
Ask students to pair up and say, "I want you to look at the information on the whiteboard. Turn and talk to your partner and think about what you notice about each of these numbers. Which numbers go together? Why? Which number or numbers don't fit in with the rest? What similarity do all the numbers share? Justify your reasoning."
Provide the following sentence stems to support students as they share their ideas:
I notice that some of the numbers ________.
The number that doesn't fit in is ________.
The numbers that go together are ________.
All of the numbers are the same because ________.
Read through the sentence frames and allow students a few minutes to discuss their ideas with their partners.
Allow a few partnerships to share their reasoning for grouping numbers in various ways.
