Age: 12–15 years
Topic: Perspective Drawing
Sub-topic: Definition and One-Point Perspective
Duration: 60 minutes

Behavioural Objectives

By the end of this lesson, students should be able to:

1. Define perspective drawing.

3. Identify the uses of one-point perspective in real-life scenarios.
4. Draw simple objects using one-point perspective.

Keywords

• Perspective Drawing
• One-Point Perspective
• Vanishing Point
• Horizon Line
• Converging Lines

Set Induction

The teacher displays a photograph of a road that appears to narrow in the distance and asks the students why the road looks smaller as it moves farther away. This introduces the concept of perspective.

Entry Behaviour

Students already know how to draw basic objects and have experience with isometric and oblique projections.

Learning Resources and Materials

• Graph paper
• Pencils, rulers, erasers
• Whiteboard and markers for demonstration
• Images of roads, train tracks, or buildings drawn in one-point perspective

Building Background/Connection to Prior Knowledge

In previous lessons, students learned about different ways to represent objects in 3D, such as isometric and oblique drawings. Today, they will explore perspective drawing, which shows objects as they appear to the human eye, especially over distance.

Embedded Core Skills

• Visual-spatial skills
• Critical thinking
• Creativity

Learning Materials

• Graph paper and drawing tools
• Models or printed images with vanishing points
• Perspective drawing templates

Reference Books

• Lagos State Scheme of Work
• Basic Technology Textbook for Junior Secondary Schools
• “Technical Drawing for Beginners” by J. O. Oloruntola

Instructional Materials

• Pencils, rulers, and graph paper
• Photographs demonstrating perspective (e.g., roads, railways)

Content

I. Definition of Perspective Drawing

• Perspective drawing is a technique used to represent 3D objects on a flat surface, giving them depth and dimension.
• It shows how objects appear smaller as they recede into the distance, mimicking the way the human eye perceives things.

II. One-Point Perspective

• One-point perspective uses a single vanishing point on the horizon line where all the lines of the object converge.
• This type of perspective is often used to draw objects facing the viewer directly, such as hallways, roads, or railways.

Steps to Draw Simple Objects Using One-Point Perspective

1. Step 1: Draw the horizon line across the paper.
2. Step 2: Mark a vanishing point on the horizon line (usually in the center).
3. Step 3: Draw the front face of the object (e.g., a square or rectangle).
4. Step 4: Draw lines from the corners of the front face toward the vanishing point.
5. Step 5: Choose a depth for the object and draw vertical or horizontal lines to close the shape.
6. Step 6: Erase the lines going to the vanishing point to finalize the object.

Examples of Objects to Draw Using One-Point Perspective

1. Road
2. Railway tracks
3. Hallway
4. Box
5. Room interior

Class Activity Discussion (FAQs)

1. What is perspective drawing?
   It is a way to represent 3D objects on a 2D surface, showing depth and distance.
2. How is one-point perspective different from other types?
   One-point perspective has only one vanishing point where all lines converge.
3. What is a vanishing point?
   It is the point where all lines appear to meet as they recede into the distance.
4. What objects are best represented using one-point perspective?
   Roads, hallways, and interiors where objects face the viewer directly.
5. What role does the horizon line play in perspective drawing?
   It separates the sky from the ground and helps position the vanishing point.
6. Can curved objects be drawn in one-point perspective?
   Yes, but it requires more advanced techniques to maintain realism.
7. What is the importance of perspective drawing?
   It helps artists and designers represent realistic spaces and objects.
8. How does one-point perspective relate to real-life observation?
   It mimics the way our eyes see objects becoming smaller in the distance.
9. What is the first step in creating a one-point perspective drawing?
   Draw the horizon line and place the vanishing point.
10. How is perspective drawing used in architecture?
    Architects use it to design and illustrate building interiors and landscapes.
