A letter is a written message sent from one person to another. It can be written by hand or typed. People write letters to share news, say thank you, invite someone, ask for something, or simply to keep in touch.
Why do we write letters?
Parts of a letter
Envelope and stamp
To send a letter you put it in an envelope, write the receiver's address clearly in the middle, write the sender's address on the top-left, and place a stamp on the top-right. Then drop it in a postbox or give it at the post office.
Simple tips for writing
Key Point: Address format = Receiver's Name + House/Flat No. + Street/Locality + City + PIN/Postal Code
An envelope is a paper cover used to send letters and small flat items. Knowing the parts of an envelope helps us write addresses correctly and put stamps in the right place so the post office can deliver the letter.
Key points to remember: write addresses neatly and clearly, place the stamp at the top-right, and make sure the envelope is properly sealed. Do not put valuable items in a plain envelope without additional protection.
Key Point: Basic postage by weight: Postage = rate_per_unit_weight × weight_in_units. Example: If rate = 5 per 10 g, treat weight in 10 g units.
What are stamps and postage?
A stamp is a small piece of paper bought from the post office and stuck on an envelope or parcel. A stamp shows that you have paid postage. Postage is the money needed to send a letter, postcard or parcel from one place to another.

Key Point: Total postage cost = number_of_items × postage_cost_per_item (use when each item costs the same).
A post office is a place in every town or village that helps people send and receive letters, cards and parcels. It is run by postal workers. The post office makes sure messages and packages travel from one place to another safely.

Key Point: Delivery time ≈ Sorting time + Transit time + Local delivery time (a simple way to think about how long a letter takes).
Who is a postman? A postman is a person who brings letters, cards and parcels from the post office to people’s homes and collects letters to take to the post office. He wears a uniform and often carries a bag and a list of addresses.
What does a postman do?
Why is the postman important? The postman connects people. Before phones and the internet, letters were the main way to send news, gifts and money. Even today, postmen help deliver exam letters, invitations, medicines and important documents.
How to send a letter? Write the address clearly, put the correct stamp, fold and put the letter in an envelope, and drop it into a postbox or give it to the postman. The post office then sorts and sends it to the right postman for delivery.
Key Point: Basic postage formula: Postage = base_rate + (rate_per_gram × weight_in_grams)
Postal items are things sent through the post office so they reach other people. They can be small and flat or big and heavy. Each type has a special name and a different way of being handled by the post office.
All postal items must show the receiver's address, return address and usually a postage stamp or payment mark. The postage depends on size, weight and the speed of delivery.
Key Point: No strict school-level math formulas are needed, but you can estimate time roughly: Delivery Time ≈ Distance ÷ Average Speed of Transport + Handling Time (time spent sorting and transferring).
When you send a letter or a card, it goes through several simple steps before it reaches the person you wrote to. Here is how mail travels in an easy-to-understand way:
1. Writing and Preparing the Letter
You write the message on paper and put it in an envelope. On the front of the envelope you write the receiver's name, full address and PIN code (a number that helps the post office find the area). You also write the sender's (your) name and address on the back or top-left corner. Finally you stick the correct stamp on the envelope.
2. Posting the Letter
You drop the stamped envelope in a local postbox or take it to the nearest post office. If you need extra services (faster delivery or proof of delivery) you can choose Speed Post or Registered Post at the post office.
3. Collection and Sorting
The local post office collects mail from the boxes and people. Mail is then sorted. Sorting means putting letters into piles based on where they must go (same street, same town, different city, or another country). Small post offices send their mail to bigger sorting centers where machines and people sort the letters further.
4. Transportation
Once sorted for the correct area, mail travels by different vehicles: bicycles or on foot for short local delivery, vans or trucks between towns, trains for long distances on land, and airplanes for very long distances or international letters. Which vehicle is used depends on how far the letter will travel and how fast it needs to arrive.
5. Local Delivery
When the letter reaches the post office near the recipient, it is sorted into the delivery list for the postman. The postman delivers the letter to the correct house or school mailbox. If the person is not at home and the service requires a signature, the postman might leave a slip asking the person to collect the mail from the post office.
6. Special Services
There are services like Speed Post (faster), Registered Post (proof and safe delivery), and Insured Post (covers loss). These use special handling and sometimes faster transport so the letter can be tracked and reaches safely.
Important Words to Remember: stamp, address, PIN code, postbox, post office, sorting, transport, postman, Speed Post, Registered Post.
Simple Tips: Always write the full address and PIN code clearly, put the right stamp, and use the sender’s address in case the mail needs to be returned.
Key Point: Address format (template): Receiver’s Name, House/Flat No., Street/Locality, City – PIN, State, Country
What is a postbox? A postbox is a locked box placed outside post offices or on streets where people drop letters and small parcels. It collects mail that postal workers pick up and take to the post office for sorting and delivery.
Where are postboxes found and how do they look? Postboxes are usually found near post offices, on busy streets, or at schools. In many places they are painted a bright color (for example, red in India) so people can easily spot them. They have a slot or opening on top or at the front for dropping letters.
How to post a letter — step by step:
What happens after you drop the letter? Postal workers collect letters from the postbox and take them to a sorting office. There the letters are sorted by area and PIN code. Letters are then sent by road, rail or air to the destination post office, where local postmen deliver them to the receiver’s address.
Important terms: Stamp (proof of payment), Post office (place to buy stamps and post letters), PIN code (a code that helps sort mail quickly).
Key Point: Basic informal letter template: [Date]\n\nDear [Name],\n\n[Opening sentence: How are you? I am fine.]\n[Body: 1–3 short sentences with news or invitation.]\n\n[Closing: With love / Yours / Yours truly,]\n[Your name]
A letter is a written message sent from one person to another. In Class 3 we learn to write simple, friendly (informal) letters to family, friends or a pen-pal. A letter has parts and follows an order so the person who reads it can understand who it is from, who it is for and what the message is.

Parts of a letter: date, address of the sender or receiver, salutation (greeting), body (main message), closing (goodbye), and signature.
Modern note: Today we also send electronic letters called emails. They are fast but the idea of writing clear messages is the same.
Why letters are important for children: Letters teach politeness, clear expression, and help keep memories and important information safe.
Key Point: Safety = Awareness + Rules + Help (from a trusted adult)

Class Activities and Exercises for the Chapter 'Here Comes a Letter' help children learn what a letter is, the parts of a letter and envelope, how letters travel, and why people send letters. Activities should be hands-on, simple and playful so Class 3 students learn by doing and observing.
Key learning outcomes: identify parts of a letter (heading, greeting, body, closing, signature), write a short friendly letter, address an envelope correctly (name, house number, street/locality, city, PIN code), understand the role of the post office and postman, and practise sequencing the steps of mail delivery.
Assessment exercises can include: fill-in-the-blanks about parts of a letter, matching address parts to envelope lines, writing a short letter from prompts, and a simple drawing labelling where mail comes from and where it goes. Use group work to involve less confident writers and to encourage discussion.
