Module 18: Using Customary and Metric Tools- Math 2A - Course Guide

Module Overview:

In this module, your student will estimate lengths using inches, feet, and yards and estimate lengths using centimeters and meters. Students will measure to determine how much longer one object is than another and compare the lengths of two objects using subtraction. Students will also measure objects to compare their length, compare the metric lengths of two objects using subtraction, and measure the length of an object by selecting and using correct tools such as rulers, yardsticks, meter sticks, and measuring tapes.

Learning Coach Notes:

Lesson #	Lesson Title	Notes
1	Estimate Using Inches, Feet, and Yards	Have your student select 5 items around the house to measure. Before they measure, first have them estimate what they think the length is, and then measure the item to see how good their estimate was.
2	Estimate Using Centimeters and Meters	Have your student choose 5 objects around the house to measure. First, have them estimate how long the objects are in centimeters or meters, and then have them measure the objects to check their measurements.
3	Compare Customary Lengths	Have your student find 2 objects to measure and compare their lengths.
4	Compare Metric Lengths	Ask your student to get 2 objects to measure using centimeters or meters and to compare the measurements.
5	Select and Use Customary and/or Metric Tools	Have your student find various objects around the house to measure and compare.

Guiding Questions

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.

Lesson Title	Question
Estimate Using Inches, Feet, and Yards	How do we estimate measurements?
Estimate Using Centimeters and Meters	How do we estimate using the metric system?
Compare Customary Lengths	How do we compare measurements?
Compare Metric Lengths	How do you compare measurements?
Select and Use Customary and/or Metric Tools	How do we choose a measuring tool to compare?

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?
