# Measurement of Length Lesson Plan: Standard and Nonstandard Units

In this lesson plan, which is adaptable for grades K-3, students use BrainPOP Jr. resources to explore non-standard and standard units for measuring length. Students then use non-standard and standard units to measure the length of various objects and themselves/their classmates.

### Students will:

- Learn about non standard and standard units for measuring length
- Use non-standard and standard units to measure the length of various objects and themselves

### Materials:

- Internet access for BrainPOP Jr.
- Interactive whiteboard (or LCD projector)
- Sidewalk chalk
- Paper and pencil for each student
- Non-standard measurement units, such as DVD cases
- Paperclips
- Rulers
- Class set of the Activity

### Vocabulary:

length; width; height; inch; foot; compare; predict; summarize

### Preparation:

Preview the Inches and Feet movie and prepare pause points for discussion.### Lesson Procedure:

- Project the Talk About It feature for the class. Demonstrate how to measure in standard and non-standard units and record the results by typing directly into the form.
- Show the Inches and Feet movie to the class.
- Pass out the Activity and have students practice measuring with the paperclip (nonstandard unit) and ruler (standard unit.)
- Take students outside. Have a student lay down on the sidewalk and demonstrate how to measure from his or her feet to his or her head. Use both nonstandard and standard measures.
- Pair students up and have them take turns measuring one another using both measurement tools. Have students record the measurements on a chart or on their own paper (perhaps the back of the activity paper they completed earlier.)
- Talk with students about the measurements they recored. Who is taller? Who is shorter?
- Bring students back to the classroom and have them write about what they learned. They could write, for example: "John is 10 bricks long. I am 6 bricks long. 10 is 4 more than 6 so John is taller."
- As a review or assessment, have students play the Game or take the Easy Quiz or Hard Quiz.
