Provide several examples of different objects or distances and ask students to reflect on them and try to guess what is the most reasonable customary unit of length that they could use for each measuring length/distance in each specific case. Just like kilometers, the distance of the Earth from the sun is measured using miles too. This unit is best used if you want to know how far one city is from another. State that miles are used to measure very large distances. The length of a football field is a good example of things measured using yards. The length of a door and the height of a person are some examples.Īdd that yard is used to measure objects that are larger than an inch or foot. Point out that feet are exactly the size of one ruler and are used to measure bigger objects.

The length of a crayon can be measured using inches. Provide a more detailed explanation for each of them:Įxplain that we use inches for small objects that are less than the length of a ruler. Point out to students that in our daily lives, we most frequently use inches, feet, and yards, whereas miles as a customary unit of length is less commonly used for everyday items.

the length of a runway of an airport is around one mile.

a regular paper clip is around one inch.

So how can we estimate how many inches, feet, yards, or miles is something? You can provide a few examples, such as: Point out that the customary units of length that we use are as follows: This system is also called the US customary system, as it’s commonly used in the US. What Are the Customary Units of Length?Įxplain to students that the customary system of measurement is a set of weights and measures that we use to measure length, weight, temperature, and capacity.

Point out that in this lesson, students will learn how to answer such questions by using the customary units of length. In previous lessons, we answered questions about how long an object is or how far it is to get from one place to another by using the metric units of length. This can also mean the distance between one object and/or place to another. Remind students that we define length as a measurement that determines how long an object is from one of its ends to the other. During these lessons, they also had an introduction of what length is and how we measure how long things are by using the metric units of length. In previous lessons, students familiarized themselves with the metric units of length, such as millimeter, centimeter, meter, and kilometer. Use these strategies in your classroom and get your students excited about learning the customary units of length! Strategies to Teach the Customary Units of Length Review Length To make these measures of length lessons engaging, math teachers can employ a variety of teaching strategies. This includes determining the different customary units of length and how they are related to each other, as well as converting larger to smaller units and vice versa. In the fourth grade, students learn about the customary units of length.
