Introduction

Welcome 2nd Graders!

Today we will learn how to compare three-digit numbers based on their values.

Your friend Mr. Alligator is going to help us learn this lesson today! In the next pages, he will be sharing everything we will be going over today.

In today’s lesson you will learn how to feed your friend Mr. Alligator!

You will first want to watch the YouTube videos, and this will show you how to feed Mr. Alligator!

Then you will complete a worksheet to show you mastered this lesson.

Check out the video below and it explains which symbol you use to compare the numbers.

Now since we know how to use these symbols, you will watch another video that will compare 2-digit numbers.

In class after reviewing all the attachments above, I will pass out a worksheet where you will compare 3-digit numbers and check your understandings.

This is how you will be evaluated on your work.
