Module 6: Compare NumbersMath 2A  Course Guide
Module Overview:
In this module, students will use different ways to make a number, make a number using baseten blocks, use placevalue concepts to represent amounts of tens and ones, and compare twodigit numbers. They will use placevalue concepts to represent amounts of hundreds, tens, and ones, compare threedigit numbers, and understand that the three digits of a threedigit number represent amounts of hundreds, tens, and ones.

Learning Coach Notes:
Lesson #  Lesson Title  Notes 

1  Number Structure (Tens and Ones)  Ask your student to share with you what they learned about how to make numbers using baseten blocks. 
2  Number Structure (Hundreds) 

3  Make Groups of 10s and 1s to Compare  Ask your student to describe what they learned about comparing numbers in this lesson. 
4  Make Groups of 100s to Compare 3Digit Numbers  In their Math notebook, have your student write and label the sign used to show a number is greater than another number, and write and label the sign used to show a number is lesser than another number. 
5  ProblemSolving Strategy: Reasoning  The Number Cards Worksheet will be found in the cutout section of the workbook if your student has a workbook. The cutout section can be found in the Table of Contents of the workbook. 
Module Guiding Questions:
When a student starts a lesson ask them questions to check for prior knowledge and understanding and to review concepts being taught. At the end of the lesson ask the questions again to see if their answer changes.

Module Video Questions:
When a student watches a video take time to ask them questions about what they watched. Suggested questions for the videos in this module are listed here. Suggestion: Have the student watch the entire video first all the way through. Then have them watch the video a second time, as they watch it pause the video and ask the questions.

Module Suggested Read Aloud Books:
Take time to read to your student or have them read aloud to you. Read a different book each day. While reading the book point out concepts being taught. You may purchase these books or find them at your local library. Suggested things to discuss while reading the book:
 What is the main idea?
 What are three things new you learned?
 How does this book relate to what you are learning about?
