Lesson Content/Board Summary
Writing Informal And Formal Letters
Types of Letters
Letters are written messages sent to communicate with others. They are generally categorised into two main types:
- Informal Letters: These are personal letters written to friends, family members, or close acquaintances. They use a casual tone and language.
- Formal Letters: These are official letters written for professional or official purposes. They follow a strict format and use formal language and tone.
Formal Letters
Purpose and Intended Recipient
Formal letters are written for specific official purposes and are addressed to individuals or organisations in a professional capacity. The intended recipients are usually:
- Employers or potential employers (e.g., job applications).
- School principals, teachers, or administrators (e.g., requests, complaints).
- Government officials or agencies (e.g., inquiries, petitions).
- Business organisations (e.g., orders, complaints, inquiries).
- Editors of newspapers or magazines (e.g., letters to the editor).
Correct Formal Letter Layout
A formal letter follows a standard layout to ensure clarity and professionalism. The key parts include:
- Sender’s Address: Your full address, usually at the top right corner.
- Date: The date the letter is written, placed below the sender’s address.
- Recipient’s Address: The full address of the person or organisation you are writing to, placed on the left margin below the date.
- Salutation: A formal greeting, such as “Dear Sir/Madam,” or “Dear Mr./Ms. [Surname]”.
- Subject/Heading: A brief, clear statement of the letter’s purpose, usually underlined or bolded.
- Body of the Letter: The main message, organised into clear paragraphs.
- Complimentary Close: A formal closing, such as “Yours faithfully,” or “Yours sincerely.”
- Signature and Name: Your signature followed by your full name printed below it.
Suitable Salutation and Complimentary Close
The choice of salutation and complimentary close depends on whether the recipient’s name is known:
- If the recipient’s name is UNKNOWN (e.g., “The Manager”), use:
- Salutation: Dear Sir/Madam,
- Complimentary Close: Yours faithfully,
- If the recipient’s name is KNOWN (e.g., “Mr. Adebayo”), use:
- Salutation: Dear Mr. Adebayo,
- Complimentary Close: Yours sincerely,
Organising the Body into Clear Paragraphs
The body of a formal letter should be organised logically into distinct paragraphs:
- Opening Paragraph: State the main purpose of the letter clearly and concisely.
- Middle Paragraph(s): Provide detailed information, explanations, or supporting points. Each new idea should start a new paragraph.
- Closing Paragraph: Summarise your request or main point and state any expected action or next steps.
Formal Vocabulary and Tone
Formal letters require precise and respectful language. Key aspects include:
- Vocabulary: Use formal words and avoid slang, contractions (e.g., “don’t,” “can’t”), and colloquialisms.
- Tone: Maintain a respectful, polite, and objective tone. Avoid emotional language, sarcasm, or overly casual expressions.
- Sentence Structure: Use complete sentences and clear, concise expressions.
Drafting, Editing, and Final Presentation
To ensure a high-quality formal letter:
- Drafting: Write a first version, focusing on getting your ideas down.
- Editing: Review the draft for clarity, grammar, spelling, punctuation, and adherence to formal tone and layout. Check for any missing information.
- Final Presentation: Ensure the letter is neatly written or typed, free from errors, and presented professionally.

Differentiation
For weaker learners: Provide partially completed formal letter templates for them to fill in. Offer simpler scenarios for practice and provide a list of formal vocabulary they can use. Pair them with stronger learners for group activities.
For faster learners: Challenge them to write a formal letter on a more complex topic or to a more specific official. Ask them to identify and correct errors in a poorly written formal letter, explaining their corrections.

Teacher Guide for Using This Lesson Plan
Before the lesson, ensure you have clear, legible samples of both formal and informal letters, preferably on charts or printed handouts, to serve as visual aids. Begin by engaging students with their prior experiences with letters to build a connection to the topic. Systematically go through the types of letters, then focus on each component of the formal letter layout, purpose, appropriate language, and tone. Model each step clearly, using the sample letters to point out features. During guided practice, circulate among groups to provide immediate feedback and correct errors. Emphasise that students should copy the Board Summary notes neatly after the main teaching points have been covered and understood. Encourage students to ask questions throughout the lesson to clarify any misconceptions. For the homework, remind students to pay close attention to the structure and formality.
