FINDING AREA 

Area is the amount of space inside a shape, and we measure it using square units, like counting how many little squares can fit inside the shape. Learning about area is important because it helps us know how much space we have for things like putting furniture in a room or planning a garden, so we can use our space better!

Let us take for example the Giant’s kitchen. Looking at the picture, how many square tiles cover the kitchen floor?

To know the number of tiles that cover the kitchen floor, we may count the square tiles that cover the floor.

 1. Count from the first row left to right, then downwards.

2. 12 square tiles can cover the kitchen floor.

3. Therefore, the area of the kitchen is 12 square units. 

Another way of finding the number of tiles that can cover the floor is:

First, count the number of tiles arranged in each row. This stands for the length side.

Then, count the number of tiles in each column. This stands for the width side.

Multiplying the length side with 4 and the width side with 3, gives us 12.

Therefore, we can say that when we multiply the side and the length gives us the same result as when we counted all the tiles that cover the floor.

Multiplying the length and side gives us the area, therefore this lead us to the formula

Area = Length X Width

Using the formula to find the area of a larger space, like a big rectangle or square, is very important because it saves us time and effort compared to counting each unit one by one. Counting can work well for smaller spaces, but as spaces get bigger, the formula helps us find the area quickly and accurately. Learning to use the formula makes it easier for us to measure and understand the size of any space, big or small, in a smart and efficient way.

Let us try to solve word problems, involving area:

Let us assume that the giant’s kitchen was extended for more space that covers another row of square tiles. What is the new area of the kitchen floor? (Originally the dimensions were 4 square units by 3 square units)

We can also solve problems about area by drawing or illustration in graphing paper or by using ruler if there is no graphing paper

 

Looking at the figure formed, the kitchen floor now have the same side length of 4 square units, the shape of the floor now becomes square.

Therefore, we can just multiply the side length by itself to get the area.

We can then use the formula:

Area = side × side or Area = s²

Solution:

Area = side x side

A = s x s

A = 4 units x  4 units

A = 16 square units

 Or we can just count the number of squares covered by the illustration.

When we measure the area of different spaces, we use units like square centimeters and square meters. Smaller spaces, like a book cover or a small garden bed, are often measured in square centimeters, while larger spaces, like walls or playgrounds, are measured in square meters. Let’s look at some examples to see how we can find the area using both of these units!

Example 1 

Emma has a rectangular picture frame that is 5 cm long and 3 cm wide. She wants to find out how much space the frame covers. What is the area of Emma’s picture frame in square centimeters?

Solution:

To find the area of the rectangular frame, multiply the length by the width.

Area = length × width

Area = 5 cm × 3 cm

Area = 15 square centimeters

So, the area of Emma's picture frame is 15 sq. cm.

Example 2

Liam has a square pool in his backyard. Each side of the pool is 6 meters long. He wants to find out the area of the pool What is the area of Liam’s pool in square meters?

Solution:

To find the area of a square, multiply the length of one side by itself.

Area = side × side

Area = 6 m × 6 m

Area = 36 square meters

So, the area of Liam's pool is 36 square meters.

  

Direction: Color each small squares that make up the figures. Find the area of each figure below by counting the number of square units.

                                                       

Direction: Assuming that each square measures 1 cm each side, find the area of the following figures using the formula: A = LxW. Write your solution in the box .

 Direction: Color the following figures on the grid. Then count the number of units around the figure. Write your answer below each figure.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Who Owns It? Let's Learn Possessive Pronoun

POSSESSIVE PRONOUN

A possessive pronoun is a word that tells us who owns something or who it belongs to. It shows that something is mine, yours, his, hers, ours, or theirs. These words help us know who owns something without saying the name every time. We use them to make sentences shorter and clearer. For example, instead of saying, “This is Jack’s pencil, and this is my pencil,” we can say, “This is his pencil, and this is mine.”

Use the motivation activity as examples.

The man owns the magical beans. The beans are his.

Mother owns the house. The house is hers.

The giant owns the treasures. The treasures are his.

Jack owns the cow. It is his.

Instead of saying, "This is Jack's cow," we can say, "This cow is his."

Rather than "This is the mother’s house," we can say, "This house is hers."

The giant is replaced by the pronoun his to show ownership.

His replaced Jack as the owner of the cow.

The different possessive pronouns are the following: mine, hers, his, ours, yours, theirs.       

Mine is used in showing you are the owner of something.      

Example: I brought a water bottle to class. The water bottle is mine.

Here, "mine" replaces "I” as owner of the water bottle the second sentence.

Hers is used in showing ownership of a female.       

Example: Sarah has a blue backpack. The backpack is hers.  

Here, "hers" replaces "Sarah" as the owner of backpack in the second sentence.

To shorten or combine ideas: Sarah has a blue backpack, and it is hers.

In this example, "hers" takes the place of saying "Sarah's backpack" again.

His is used in showing ownership of a male.        

Example: Tom brought a lunchbox to school. The lunchbox is his.

Here, "his" replaces "Tom" as the owner of the lunchbox in the second sentence.

To shorten or combine ideas: Tom brought a lunchbox to school, and it is his.

In this example, "his" stands in for "Tom's lunchbox" to avoid repetition. 

 

Yours is used in showing ownership by someone you are talking to.        

Example: You left a notebook on the desk. The notebook is yours.

Here, "yours" replaces "you" as the owner of notebook in the second sentence.

Combined: You left a notebook on the desk, and it is yours.

In this example, "yours" takes the place of "your notebook," making the sentence simpler and avoiding repetition.

 

Ours is used to indicate that something belongs to you and others in your group.

Example: We have a big dog and a small dog. The dogs are ours.

Here, "ours" replaces "we" as owners of the dogs in the second sentence.

Combined: We have a big dog and a small dog; the dogs are ours.

In this example, "ours" takes the place of "our dog," making the sentence more concise and avoiding repetition.

 

Theirs is used in showing ownership by many persons being talked about.        

Example: The learners forgot their backpacks in the classroom. The backpacks are theirs.

Here, "theirs" replaces "the learners" as the owners of backpacks in the second sentence.

Combined: "The learners forgot their backpacks in the classroom, and those backpacks are theirs."

In this example, "theirs" takes the place of "the learners' backpacks," simplifying the sentence and avoiding repetition.
