## Distance Measurement

### Lesson Plan Overview / Details

This lesson begins to move from the concepts of "approximate" units of measurement to more precise, standardized measurement units. Pacing, Chaining, Taping and the use of odometers and electronic tools to measure distance are covered. Students will be able to demonstrate one or more of the methods for measuring distance covered in this lesson.

### Activities in this Lesson

• Distance Measurement - Hooks / Set

As students enter the classroom today, there will be actual tools that are used in the various measurement techniques for land measurement (Chain, Tape, Odometer, and if available, an Electronic Measuring Device). Teacher posts an A, B, C, D picture with qualifiers that tell how many people needed to use the tool and cost (cheap/expensive). Ask the students which tool they would select to measure 1. perimeter of the ag building and 2. survey for property markers for a new building site. When they have chosen, have them raise their hands for A, B, C, or D.

The discussion will be on the need for standardized tools in order to have accurate measurements. As we look at the tools on display lead the discussion towards the accuracy of one tool over the other. Depending on the objective of the measurement project, a more accurate form of measurement may be required.

If you don't have some of these tools you may substitute a good picture, or better yet, it may be time to become acquainted with some local contractors or your local equipment rental yard and ask to borrow tools to use in this lesson (this may turn into finding a good guest speaker as well).

• This lesson is comprised of a power point presentation titled, "Distance Measurement". After the discussion about the various tools that are on display, handout a Student Outline to each student. As I discuss each slide, the students follow along on their handout and take notes. We ask questions and discuss each item.
