Converting Measurements to Solve Real Life Distance Problems

This lesson teaches how to solve real-life distance problems by converting measurements. It reviews the metric system, focusing on kilometers, meters, centimeters, and millimeters, and explains how to convert between these units. The lesson also covers solving word problems, identifying key information, and addressing common misunderstandings in measurement. It emphasizes the importance of choosing the correct mathematical operations and provides examples, such as determining if two people are taller than a certain height when combined. The lesson concludes with a practical problem involving a height requirement for a roller coaster ride.

Which of the following is NOT a unit of measurement in the metric system?

• Centimeter

• Meter

• Inch

• Kilometer

What is the first step in solving a word problem involving measurements?

• Convert all units to meters

• Add all given numbers

• Draw a diagram

• Identify what the problem is asking

If Toby is 1 meter and 50 centimeters tall, how tall does Marla need to be for their combined height to be 3 meters?

• 1 meter and 50 centimeters

• 2 meters

• 1 meter and 60 centimeters

• 1 meter

Why is it incorrect to assume that a larger number always indicates a longer distance?

• Because larger numbers are always in meters

• Because different units represent different lengths

• Because numbers are not related to distance

• Because all units are the same
