Reference Materials

The following resources was used in planning this lesson:

9 Years Basic Education Curriculum
Lagos State Unified Scheme of Work for Junior Secondary Schools
BBC Bitesize – 3D Shapes and Their Properties (https://www.bbc.co.uk/bitesize/topics/zjv39j6/articles/zcsjqty)
Relevant Textbooks

Instructional Materials

The teacher will teach this lesson with the aid of:

Real models of cube, cuboid, cylinder, cone, sphere, and prism
Chart showing different views of solid shapes
Graph sheet and drawing pencils
Whiteboard and markers
Multimedia image display (if available)

Rationale for the Lesson

Understanding views and plans helps pupils interpret technical drawings and recognise how 3D objects are represented in practical fields like engineering, design and architecture.

Prerequisite/Previous Knowledge

Pupils already know basic properties of 3D solids such as faces, edges and vertices from previous classes.

Lesson Content/Board Summary

Views, Plans and Sketches

Types of Views of Solid Shapes

A view is the way an object appears when looked at from a particular direction. Views help us represent 3D objects in 2D form.

The following are the main views used in drawings:

Front view
Side view
Top view (Plan)

Views of Common Solids

Every solid shape has different views depending on how it is observed. These views help us understand the shape’s structure.

The following are views of common solids:

A cube shows a square in all views.
A cuboid shows rectangles of different dimensions.
A cylinder shows a rectangle in side view and a circle in top view.
A cone shows a triangle in front view and a circle in plan view.
A sphere shows a circle in all views.
A prism shows rectangles and polygons based on its ends.

Plan (Top View)

A plan is the view of an object from above. It shows the outline or shape of the top surface.

Examples include:

A cube has a square plan.
A cylinder has a circular plan.
A cuboid has a rectangular plan.

Sketches of Solids

A sketch is a freehand drawing used to represent an object quickly without measurement. It shows shape and major features.

Teaching Methods/Instructional Techniques

Discussion, Explanation, Demonstration, Guided Practice, Visual Aids, Group Work

Instructional Procedures

To deliver this lesson, the teacher will adopt the following steps:

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: Uses real objects like a box, tin, and ball to ask pupils how these objects would look from different sides. Links responses to views, plans, and sketches.
Pupils’ Activity: Observe objects and answer teacher’s questions.
Learning Point: Pupils become aware that objects look different from different directions.

Step 2: Explanation of Views of Solids

Time: 10 minutes
Teaching Skill: Explanation
Teacher’s Activity: Defines views and demonstrates front, side, and top views using models of solids.
Pupils’ Activity: Watch demonstration and identify the views.
Learning Point: Pupils understand the meaning of views and how they are formed.

Step 3: Plan (Top View) and Elevations

Time: 10 minutes
Teaching Skill: Demonstration
Teacher’s Activity: Shows the plan view of cube, cuboid, cylinder, cone and sphere using charts.
Pupils’ Activity: Observe the displayed charts.
Learning Point: Pupils learn how to identify the top view of common solids.

Step 4: Sketching Views of Solids

Time: 10 minutes
Teaching Skill: Guided Practice
Teacher’s Activity: Demonstrates how to sketch simple views of solids from the board summary. Guides pupils to practice drawing.
Pupils’ Activity: Draw the views and sketches in their notebooks.
Learning Point: Pupils develop drawing and representation skills.

Step 5: Note-Taking

Time: 3 minutes
Teaching Skill: Reinforcement
Teacher’s Activity: Leads pupils to copy the board summary.
Pupils’ Activity: Copy notes.
Learning Point: Pupils retain the core content of the lesson.

Step 6: Evaluation/Review

Time: 5 minutes
Teaching Skill: Assessment
Teacher’s Activity:
The teacher evaluates the learning by asking the following questions:

What is a view?
State the three main types of views.
What is the plan view of a cylinder?
Describe the views of a cube.
Draw the front view of a cone.
Pupils’ Activity: Answer questions and complete tasks.
Learning Point: Pupils demonstrate understanding of views, plans and sketches.

Step 7: Conclusion

Time: 2 minutes
Teaching Skill: Closure
Teacher’s Activity: Summarises the lesson and links it to real-life uses like engineering drawings.
Pupils’ Activity: Listen and ask questions.
Learning Point: Pupils appreciate the practical relevance of the topic.

Lesson Keywords

View – How an object appears from a direction
Plan – Top view of an object
Elevation – Front or side view of an object
Sketch – Freehand drawing of an object
Solid Shape – A three-dimensional object with volume

Differentiation

Use peer support, varied drawing tools, slow-paced demonstrations, and additional examples for learners needing extra help.

Note for Teachers Using this Lesson Plan

Ensure pupils use drawing tools neatly. Reinforce accuracy by showing real-life applications such as building plans or product design.
