Lesson Content/Board Summary
Writing Informal And Formal Letters
Types of Letters
Letters are a common way to communicate in writing. They can be broadly categorised into two main types:
- Informal Letters: These are personal letters written to friends, family members, or close acquaintances. They are usually casual and friendly in tone.
- Formal Letters: These are official letters written for professional or official purposes. They are addressed to people in positions of authority, organisations, or for business matters. An application letter, for example, is a type of formal letter.
Characteristics of Informal Letters
Informal letters typically have the following features:
- Purpose: To share personal news, invite, thank, or express personal feelings.
- Recipient: Friends, family, or close relations.
- Tone: Casual, friendly, personal, and relaxed.
- Language: Everyday language, contractions (e.g., “I’m,” “don’t”), slang, and informal expressions are common.
- Layout: Less strict, often includes only the writer’s address and date, a casual salutation, and a friendly close.
- Content: Focuses on personal matters and conversations.
Characteristics of Formal Letters (e.g., Application Letter)
Formal letters, such as application letters, have specific features that distinguish them:
- Purpose: To apply for a job, request information, make a complaint, give official notice, or conduct business.
- Recipient: People in authority, organisations, companies, or official bodies.
- Tone: Respectful, objective, serious, and polite. Avoids emotional language.
- Language: Formal vocabulary, complete sentences, and grammatically correct English. Contractions and slang are avoided.
- Layout: Follows a strict format including:
- Writer’s address and date.
- Recipient’s address.
- Formal salutation (e.g., “Dear Sir/Madam,” “Dear Mr. Smith,”).
- Clear subject line.
- Body organised into clear, concise paragraphs.
- Formal complimentary close (e.g., “Yours faithfully,” “Yours sincerely,”).
- Writer’s signature and full name.
- Content: Focuses on the specific official matter, presenting facts clearly and concisely.

Differentiation
Support for weaker learners: Provide simpler letter excerpts with clear indicators of formality or informality. Use flashcards with keywords and their definitions. Pair them with stronger learners for guided practice.
Extension for faster learners: Challenge them to write a short paragraph explaining why a specific letter excerpt is formal or informal, identifying at least two characteristics. Ask them to brainstorm more scenarios for each letter type.

Teacher Guide for Using This Lesson Plan
Before the lesson, ensure you have prepared clear examples of both formal and informal letter excerpts, either written on the board, printed, or displayed using pictorial aids. During the introduction, engage students by asking about their personal experiences with written communication. Clearly explain the distinct purposes and characteristics of formal and informal letters, using the board summary as a guide. Encourage active participation during the guided practice by having students explain their reasoning for identifying letter types. Pay close attention to common errors, such as confusing the tone or purpose of the two types. Students should copy the Board Summary notes into their notebooks during the designated note-taking step. Conclude by reinforcing the main learning points and setting appropriate homework to consolidate their understanding.
