Instructional Materials

The teacher will teach this lesson with the aid of:

Computer system (desktop or laptop)
Mouse (wired or wireless)
Mouse pad (if available)
Projector or large monitor (if available) for demonstration
Charts/pictures showing mouse parts and operations

Rationale for the Lesson

The mouse is one of the most common input devices used to control what happens on a computer screen. Understanding its parts and operations helps pupils use computers effectively for learning, typing, and basic tasks.

Prerequisite/Previous Knowledge

Pupils have seen a mouse before and have basic knowledge of input devices such as keyboard and mouse.

Lesson Content/Board Summary

Input Device – Mouse

Definition of Mouse

A mouse is a pointing input device used to control the pointer (cursor) on the computer screen and select items by clicking.

Features/Parts of a Mouse

The following are common features/parts of a mouse:

Left button (primary button) for selecting and opening items.
Right button (secondary button) for showing options/menus.
Scroll wheel/middle button for scrolling and quick navigation.
Sensor/ball (older mouse uses a ball; modern mouse uses an optical/laser sensor) for tracking movement.
Cable and USB connector (for wired mouse) or battery compartment (for wireless mouse).
Mouse body/grip area for holding and moving the mouse.

Functions of a Mouse

The following are functions of a mouse:

Moving the pointer on the screen.
Selecting items such as icons, files, and buttons.
Opening programs and documents.
Dragging and dropping items to a new location.
Scrolling through documents and web pages.

Mouse Operations

The following are basic mouse operations:

Pointing: Moving the pointer to an item on the screen.
Clicking: Pressing and releasing the left mouse button once to select an item.
Double-clicking: Pressing the left button twice quickly to open a file, folder, or program.
Right-clicking: Pressing the right button once to display a list of options.
Dragging: Holding down the left button while moving the mouse to move an item.
Dropping: Releasing the left button after dragging to place the item.
Scrolling: Using the scroll wheel to move up or down a page or document.

Teaching Methods/Instructional Techniques

Discussion, Lecture, Demonstration, Question and Answer, Visual Aids

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher displays a mouse and asks pupils to name it and state what it is used for, then links responses to the lesson topic.
Pupils’ Activity: Pupils identify the mouse and respond to questions.
Learning Point: The mouse is a common input device used to control the pointer on the screen.

Step 2: Definition of Mouse

Time: 6 minutes
Teaching Skill: Explanation
Teacher’s Activity: The teacher defines the mouse as a pointing device and writes the definition on the board, giving short examples of where it is used.
Pupils’ Activity: Pupils copy the definition and mention places they have seen a mouse used.
Learning Point: A mouse is an input device used to control the cursor and select items on the screen.

Step 3: Features/Parts of a Mouse

Time: 7 minutes
Teaching Skill: Demonstration
Teacher’s Activity: The teacher points to each part of the mouse (left button, right button, scroll wheel, sensor/ball, cable/USB or battery compartment) and explains the name and basic use of each.
Pupils’ Activity: Pupils observe closely, identify parts, and copy notes.
Learning Point: The mouse has parts that support clicking, scrolling, and movement tracking.

Step 4: Functions of a Mouse

Time: 7 minutes
Teaching Skill: Explanation and Illustration
Teacher’s Activity: The teacher lists the functions of the mouse and demonstrates selecting an icon and opening a folder on the screen.
Pupils’ Activity: Pupils state functions and relate them to what they observed on the screen.
Learning Point: The mouse helps users select, open, move items, and navigate on the computer.

Step 5: Mouse Operations

Time: 10 minutes
Teaching Skill: Demonstration
Teacher’s Activity: The teacher demonstrates pointing, clicking, double-clicking, right-clicking, dragging and dropping, and scrolling using simple items on the desktop and a document page.
Pupils’ Activity: Pupils observe the operations and describe what happens on the screen for each operation.
Learning Point: Mouse operations control selection, opening, movement of items, and page navigation.

Step 6: Practical Activity (Guided Practice)

Time: 5 minutes
Teaching Skill: Guided Practice
Teacher’s Activity: The teacher guides pupils to practice mouse operations in turns: select an icon, open a folder, drag an item, and scroll a page, correcting improper handling.
Pupils’ Activity: Pupils practice in turns and assist one another to perform the operations correctly.
Learning Point: Practical use improves accuracy and confidence in mouse handling.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define a mouse as an input device.
List four features/parts of a mouse.
State three functions of a mouse.
Explain the difference between clicking and double-clicking.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 0 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the definition, features, functions, and operations of the mouse and corrects mistakes observed during practice. Assignment: write the features of a mouse and describe five mouse operations.
Pupils’ Activity: Pupils copy the summary and assignment.
Learning Point: Proper understanding of mouse parts and operations supports effective computer use.

Lesson Keywords

Mouse – A pointing input device used to control the cursor and select items on the screen.
Cursor/Pointer – The moving arrow or symbol that shows the position on the screen.
Click – Pressing and releasing the left mouse button once.
Double-click – Pressing the left mouse button twice quickly to open an item.
Right-click – Pressing the right mouse button once to show options.
Drag and Drop – Holding the left button to move an item, then releasing to place it.

Differentiation

Pupils who need support will practice with a mouse pad and simple tasks such as pointing and single clicking, while advanced pupils will practice dragging files, right-click menus, and controlled scrolling within a document.

Note for teachers using this lesson plan

Ensure every pupil practices the mouse operations in turns and enforce careful handling of the equipment. Use clear, simple tasks on the desktop for demonstration and practice. Emphasize examinable points: definition, parts, functions, and correct meaning of each mouse operation.
