### In this 3rd grade math video on how to **measure** the area of a **shape**...

Zuri and Freddie find an old computer in the landfill. They start playing Block Builders, a game where you can build and explore. Zuri and Freddie are curious about the structures they’ve built and want to know how you calculate the area of their **shapes.** In this video, Zuri and Freddie learn how to find the area of a **shape** by counting **unit squares**.

### What is the area of a **shape**?

Let’s learn more about finding the area of a **shape** and determining the area with **square units** in 3rd grade.

#### Area of a **shape** definition

The area of a **shape** is the amount of space it takes up on a flat **surface.** Area is always **measured** in **square units.**

### What is a **unit square?**

A **unit square** is a special square that **measures** one unit in **length ** on each **side** and thus has an area of one **square unit.** **Unit squares ** are used to determine area in **square units.**

####
**Unit square** definition

We define **unit squares** as taking up one **square unit ** of area. We can lay **unit squares** side by side, without spaces or overlaps, across the entire **surface** of a **figure.** This helps us **measure** the amount of space, or area, the **figure** takes up.

#### How do you count **unit squares?**

Count the number of **square units** needed to cover a **surface** one at a time. This will calculate the total area and is why the area is **measured** in **square units.**

#### What are **square units?**

Let’s explain the relationship between area and **square units:** **square units** are used to **measure** area. This is why questions ask you to find the area in **square units** and why is the area labeled with **square units.**

#### What is the definition of **square units?**

The definition of **square units** is a quantity of **measure** used to determine the amount of space a **figure** takes up on a flat **surface.** The area of a **shape** is expressed in **square units.** How would you calculate **square units?** Let’s say a **shape** is covered by 40 **unit squares,** you would say its area **measures** 40 **square units.**

### How do you find the area of a **shape** in **square units?**

Finding the area of a **shape** is simple. After laying **unit squares** across the entire **surface** of a **figure**, count each square. For example, you can draw **unit squares** across the entire **surface** to show the area of the **rectangle.** This is how to find the total area of a **shape.** Finally, label the area of a **figure** in **square units.**

### How to find the area of an irregular **shape?**

Finding the area of an odd **shape** is the same. After laying **unit squares** side by side, across the entire **surface** of the irregular **figure,** count each square.

### Area Examples

Below are examples of area. To find the area of each **figure** in **square units,**simply count the **unit squares** that cover each.

Comparing the area of **irregular shapes** and **regular shapes.**

Comparing the area of two **irregular shapes**.

### Summary of Steps: Finding Area

First, lay

**unit squares**across the entire**surface**of the**figure.**Next, carefully count each square.

Finally, label the area of the

**figure**in**square units.**
