## What Is Length? A Kid-Friendly Definition

Let's start out with an easy way to explain the meaning of length to your students!

Length is the word we use to explain the measurement of how long an object or distance is. It is typically measured in units such as metres or centimetres.

In primary school, students typically begin by learning basic concepts related to length, such as:

- Measurement tools — Ruler, tape measure, metre stick, etc.
- Units of measurement — Centimetre, metre, kilometre, etc.
- Comparing and ordering lengths — Shorter, longer, tallest, shortest, etc.

## Units of Measuring Length

In Australia, students learn to measure length using the units of the metric system. Because it's based on units of 10, the metric system makes it easy for students to convert between different units of measurement.

Here are the most common length measurements that your students will likely use in primary school:

### Millimetre (mm)

This is the smallest unit of length in the metric system. One millimetre is equal to 1/1000 of a metre.

### Centimetre (cm)

One centimetre is equal to 1/100 of a metre. This unit of length is found on your classroom ruler.

### Metre (m)

This is the basic unit of length in the metric system. One metre is equal to 100 centimetres.

### Kilometre (km)

One kilometre is equal to 1000 metres and is used for measuring longer distances, such as the distance between cities or countries.

## How to Teach Length

Looking for some fun ways to teach your students about length? Explore this whole collection for printables and digital activities, and take a look at some fun ideas from our teacher team!

**Measure Yourself**— This is an activity that never gets old for students — measuring themselves with a measuring tape! Have students measure their height and then compare their height to their classmates. Students should write down each measurement, and then they can make comparisons such as who is taller or shorter.**Scavenger Hunt**— Scavenger hunts add an element of mystery to this maths skill. Hide various objects around the classroom and have students use a ruler to measure the length of each object.**Explore Non-Standard Measurement**— Before introducing formal measurement tools, using non-standard items such as crayons and paper clips to measure items in the classroom is a good way to help students understand how items relate to one another in size.**Develop a Length Obstacle Course**— Create an obstacle course using cones, hula hoops, and other items. Have students measure the length of the course using a tape measure or metre stick. Once they're done, allow them to get active by actually moving through the course.**Take a Maths Walk With Your Rulers**— This is an excellent idea for real-world application! Take a walk around your school and have students measure the length of different objects they encounter along the way, such as the length of the hallway or the height of a door.
