#### Introduction

(5 minutes)
• Project the Alligator Greater Than, Less Than song on the wall or whiteboard using a computer. Explain to the students that you are going to play a song about an alligator who likes to eat numbers.
• Pass out the I Notice, I Wonder, I Learned worksheet to each student. Provide students with pencils to use to record their ideas.
• Explain to the students that as they watch the video, you want them to think about something they notice or wonder. Play the video and pause every so often to model "noticing" and "wondering" things about the video (e.g. I wonder why the alligator ________? I notice that the alligator ________. I wonder what ________ means). Continue this process and watch the entire video with students.
• Provide students with sentence stems and frames to support them as they jot down their ideas on the I Notice, I Wonder, I Learned worksheet. Encourage students to use complete sentences.
• Have students turn and talk to a partner to share one thing they notice or wonder about what they saw on the video.
• Explain to the students that today they are going to learn how to explain if a three-digit number is less than, equal to, or greater than another three-digit number. Tell them to hold on to their I Notice, I Wonder, I Learned worksheets because they will be filling out what they learned at the end of the lesson.
