## What our Measuring Length lesson plan includes

Lesson Objectives and Overview: Measuring Length teaches students how to measure various lengths using both standard and metric units. The lesson describes why people need to know the length of certain objects or the distance between two places. Students will discover that there are many ways to measure the length of something. They will learn about the metric system and the units it uses to measure. By the end, they will know the difference between the metric and standard methods and how to use both.

Two pages of content outline the two methods for measuring length. First, the lesson describes what length means. It then defines the standard method and the metric system. It explains how the standard method uses inches, feet, yards, and miles to measure objects or distances of various lengths. Students will learn that smaller objects, like pencils or desks, require inches or feet as the unit of measurement. Larger objects, however, would use yards or miles, such as tennis courts and state distances.

The lesson then describes the metric system. Students will discover that many countries use the metric system and not the standard method that the U.S. uses. The metric system involves units that increase or decrease by factors of 10. People most often use millimeters, centimeters, meters, and kilometers, which are actually increasing or decreasing by factors of 100. The lesson provides a couple tables that summarize the units and conversion rates for the two methods.

### MEASURING FEET ACTIVITY

Students will work alone and with others for the activity. First, they will read a short passage about why a foot is 12 inches. Then they will measure their own feet and two others’ feet. Next, they will measure the distance across a room. Then they will count how many steps it takes them to get across the room. They will also count the steps of the same two people.

### MEASURING LENGTH PRACTICE WORKSHEET

For the practice worksheet, students will first measure seven lengths using the standard method. They will measure to the nearest quarter-inch. Next, they will use the metric system to measure the same seven lengths. This time, they will measure to the nearest whole number.

### MULTIPLE CHOICE HOMEWORK ASSIGNMENT

The homework assignment requires students to answer 11 questions. Several of them focus on figuring out which unit to use to measure certain things, such as the distance between two cities. Other questions focus on testing students’ ability to convert units.
