For the past two days, we have compared two numbers, sometimes with the same number of digits and sometimes not. Today we are going to compare a group of numbers to put them in order. We might put them in order from least to greatest or from greatest to least.

Note to the Teacher: In today’s lesson, students extend their understanding of comparing numbers by ordering numbers from greatest to least and least to greatest.
1.TEACHER SAY: Let's try this first with a group of easier numbers. Open your student book to page Lesson 29: Apply.
STUDENTS DO: Open student book to page Lesson 29: Apply.
TEACHER SAY: Th e directions ask us to write these numbers in order from least to greatest, so first we will decide which of these numbers is the smallest. Look at all five numbers and then Whisper to me which is the smallest number.
STUDENTS DO: Whisper: 2.
TEACHER SAY: You are right. Two is the smallest number in this group, so we will write 2 in the first empty box.
STUDENTS DO: Write 2 in the first box.
TEACHER SAY: Take a look at the four numbers that are left. If it helps you, you can cross out the 2 since we already used it. Which of the four numbers that are left is smallest? Whisper your answer to me.
STUDENTS DO: Whisper: 3.
TEACHER SAY: Yes, the next smallest number is 3. Write 3 in the second box. Remember, if it helps you stay organized, you can cross out the 3.
STUDENTS DO: Write 3 in the second box.
TEACHER SAY: On your own now, please take a few moments and complete the first problem, writing the numbers in order from least to greatest. If you finish before others, you can draw a picture of yourself comparing numbers.
STUDENTS DO: Finish writing the first set of numbers in order from least to greatest.
TEACHER DO: Walk around to observe students as they work. Take note of students who may need additional instruction or support. Identify students who may be able to help others if needed. After 2 to 3 minutes, use an Attention Getting Signal.
TEACHER SAY: Please turn to your Shoulder Partner and compare your work. Did you order them in the same way?
STUDENTS DO: Work with a Shoulder Partner to compare work. Discuss differences.
TEACHER DO: Select one pair of partners to write their answer on the board.
STUDENTS DO: Selected students write their answer on the board.
TEACHER DO: Make sure the answer on the board is correct.
TEACHER SAY: Check your work. Do you have the same order in your book? If not, correct your work.
STUDENTS DO: Check work. Make corrections if necessary.
2.TEACHER SAY: Great job ordering the first set of numbers. Think about that same set of numbers. If I asked you to write those numbers in order from greatest to least, which number would we start with? Please Whisper that to me.
STUDENTS DO: Whisper: 17.
TEACHER SAY: That is right. 17 is the largest, or greatest, number in this list. Which number would come next if we were ordering the numbers from greatest to least? Please Whisper that to me.
STUDENTS DO: Whisper: 9.
TEACHER SAY: Great thinking. Did you notice that, if we order these numbers from greatest to least, we take the list we have on the board and go backward?
TEACHER DO: At the top of the list the students wrote, write Least to Greatest. Next to it, write the same numbers from greatest to least with the title Greatest to Least.
TEACHER SAY: What questions do you have about ordering these numbers in both ways?
STUDENTS DO: Ask questions if needed.
TEACHER DO: Answer questions as needed.
3.TEACHER SAY: In your student book, you and your Shoulder Partner will now work together on the next lists of numbers. The first problem asks you to write the numbers in order from least to greatest. The last two problems ask you to write the numbers in order from greatest to least.
STUDENTS DO: Work with Shoulder Partner to complete the three practice problems in the student book.
TEACHER DO: As students work, walk around to off er suggestions or help as needed. Note who understands and who struggles with this content.
