</div>### Introduction activity(20 minutes) 

**1. Quick Review of Perimeter**

Write on the board:

Perimeter = the total distance around the outside of a shape.

Say:

“If I walk all the way around the edge of a soccer field, what am I measuring?”

Let students respond:

“The perimeter!”

**Next example:**

“Imagine you’re putting a fence around your garden. You need to know how much fencing to buy. That’s the perimeter—the total length around it.”

Draw a rectangle on the board to represent a garden

Label: Length = 6 meters, Width = 4 meters

Ask:

“How much fencing would I need to go all the way around?”

Guide them: 6 + 4 + 6 + 4 = 20 meters

**2. Transition to Area**

Ask:

“What do we mean when we talk about the area of a shape?”

(Wait for responses. Guide as needed.)

Then explain:

“Area is the amount of surface inside the shape. It tells us how much space we’re covering.”

Real-life example:

“If I want to put carpet on the floor of a room, I’m not just measuring around it—I need to know how much space the carpet needs to cover. That’s the area.”

Use the same rectangle drawing:

Say:

“This could be the shape of a room. If I wanted to put tiles or carpet in here, I’d need to know how much flooring material to buy. That’s the area!”

- Engage: Ask students, “How can we measure how much space a shape takes up on a surface?”
- Introduce the word "Area" and explain that it is the amount of space inside a shape.
- Show a square and a rectangle on the board and ask students how they are different and similar.

**Define:**

- Square: A shape with 4 equal sides and 4 right angles.
- Rectangle: A shape with opposite sides equal and 4 right angles.
- Rectangle: Area = length × width
- Square: Area = side × side

###  Main Activity (65 minutes)

**Word Problems: Area of Squares and Rectangles (20 minutes)**

**1. Rectangle – Carpet a Room:**

You are carpeting a rectangular bedroom that is 5 meters long and 4 meters wide. How much carpet do you need to cover the floor?

Shape: Rectangle

Formula: Area = length × width

Solution: 5 × 4 = 20 square meters

**2. Rectangle – Tiling a Kitchen:**

A rectangular kitchen floor is 6 meters long and 3 meters wide. How many square meters of tiles will cover the floor completely?

Shape: Rectangle

Formula: Area = length × width

Solution: 6 × 3 = 18 square meters

**3. Square – Small Rug:**

You are placing a square rug in your reading corner. Each side of the rug is 2 meters long. What is the area of the rug?

Shape: Square

Formula: Area = side × side

Solution: 2 × 2 = 4 square meters

 **4. Square – Garden Plot:**

A square garden has sides that are 7 meters long. How much area will you cover if you plant flowers in the whole space?

Shape: Square

Formula: Area = side × side

Solution: 7 × 7 = 49 square meters

**Team-Based Area Drawing Game (25 minutes)**

**Objective:**

Each team will draw a layout of a real-life space (garden, bedroom, or classroom) using only squares and rectangles, then calculate the area of each object they include.

**Step-by-Step Instructions:**

1\. Divide the Class:

Team 1: Garden Designers

Team 2: Bedroom Planners

Team 3: Classroom Arrangers

 **Team Tasks: Each team must:**

- Design a top-down view of their space
- Include at least 5 real items (all squares or rectangles)
- Label each item with length, width, and area
- Add a title and decorate the drawing

**Team Topics and Ideas:**

**Team 1 – Garden**

- Vegetable bed (2m × 1.5m)
- Flower patch (1m × 1m)
- Pathway (0.5m × 4m)
- Grass area (3m × 2m)
- Bench (1.2m × 0.5m)

**Team 2 – Bedroom**

- Bed (2m × 1.5m)
- Rug (1.5m × 1m)
- Desk (1m × 0.5m)
- Bookshelf (1.2m × 0.6m)
- Window (1m × 1m)

**Team 3 – Classroom**

- Teacher’s desk (1.5m × 0.8m)
- Student desk (1m × 0.5m)
- Whiteboard (2m × 1m)
- Bookshelf (1m × 0.5m)
- Carpet area (2m × 3m)

**Wrap-Up:**

- Have each team present their layout, explain their measurements, and compare total areas. You can even give awards for:
- Most creative layout
- Most accurate math
- Best teamwork

### Review Questions(5 minutes)

- How are the formulas for squares and rectangles similar or different?
- Can you explain what 'area' means in your own words

### Follow Up Task(20 minutes)

**Activity: Measuring Areas in the Classroom**

**Instructions:**

- Form small groups (2–3 students each).
- Assign or let students choose 3–5 objects in the classroom that are square or rectangular in shape.

**Examples of objects:**

- Book cover
- Student desk
- Window
- Student desk
- Whiteboard
- Door

**3. Measure:**

Measure the length and breadth (for rectangles) or the side (for squares) of each object using a ruler or tape measure.

Record the measurements.

4\. Calculate:

Use the correct formula:

Square: Area = Side × Side

Rectangle: Area = Length × Breadth

Work out the area for each item.

5\. Record Findings:

Fill a table like this:

6\. Discuss:

Which object had the largest area?

Which object had the smallest area?

Why is measuring area important in real life?

### Expected learning outcome 

**Knowledge building**

- Understand the meaning of area.
- Measure length and breadth accurately.
- Apply formulas for the area of a square and a rectangle.

**Skill building**

- Calculate the area of classroom objects.
- Compare the areas of different objects.
