Key Point: Area of a rectangular room = length × breadth (A = l × b). Example: a 4 m by 3 m room has area 12 m².
A house is a building where people live. It has many parts that keep us safe, comfortable and help us do daily work. Below are the main parts of a house and what they do:
Each part has materials and features: roofs can be made of tiles, sheets or concrete; walls of bricks or wood; windows can have glass and grills. Good houses have proper doors and windows for light and air, a strong roof, safe stairs and a clean bathroom and kitchen.
Why these parts are important:
Simple ways to learn: Walk around your home and name each part. Ask why it is there and what it does. That helps understand how every part makes the house a good place to live.
Key Point: Area of a rectangular room = Length × Breadth (use metres). Useful for buying floor mats or carpets.
Every house has different rooms. Each room has a special job or function. Knowing the rooms and their functions helps us use the house safely and comfortably.
Good rules for rooms:
In the story 'Chhotu's House', Chhotu learns what each room is for and how his family uses them. Seeing real rooms helps children understand safety and manners — like removing shoes in the living room, washing hands after the toilet, and not running in the house.
Key Point: Area of a rectangular room = length × width. (Use same units, e.g., metres × metres = square metres)
What are building materials?
Building materials are the things used to make houses and other buildings. People choose materials based on what is available, the weather, money, and how strong or long-lasting the material is.
Common building materials
Types of houses (simple way to group them)
Choosing the right materials
People pick materials based on climate and availability. For example, in a rainy place, sloping roofs with good tiles or metal sheets keep houses dry. In hot places, thick mud walls keep homes cool. Safety and strength are very important — a strong foundation and good walls protect people from wind and storms.
Care and maintenance
Houses need care: fixing leaks, replacing broken tiles or thatch, painting walls, and checking the foundation. Regular maintenance helps houses last longer.
Simple safety tips for houses
Key Point: Area of a rectangular rug or bed cover = length × width (use same units, e.g., metres × metres = square metres). Example: a rug 2 m × 1.5 m has area 3.0 m².
What are furniture and household items? Furniture and household items are objects found in a home that help people live comfortably and do daily tasks. Furniture includes things we sit, sleep, eat or work on (for example: chairs, beds, tables). Household items include cooking utensils, cleaning tools and small appliances (for example: plates, broom, fan).

Key Point: Handwashing 'formula' (easy steps): Wet hands + Soap + Scrub for 20 seconds (palms, backs, between fingers, under nails) + Rinse + Dry.
What is cleanliness and hygiene?
Cleanliness means keeping our body, clothes, home and surroundings free from dirt and waste. Hygiene means the habits we follow to stay healthy and prevent germs from causing illness.
Why it is important (simple points for Class 3):

Key Point: Emergency numbers (India): 112 (general), 100 (police), 101 (fire), 102 (ambulance)
What is Safety at Home?
Safety at home means keeping ourselves and others free from harm while doing everyday things at home. We learn simple rules and habits so that the house stays a safe place for everyone, especially children, elders and pets.

Key Point: Total chores = Chore1 + Chore2 + ... + ChoreN (count of tasks in a day or week)
What it means: Family roles and household work means the different jobs that people at home do to keep the house clean, safe and comfortable. These jobs are called household chores. Every family member can do some chores according to their age and ability.
Who does what:
Why sharing chores is important:
How to share work fairly:
Safety and rules: Children should not use sharp knives, heavy stoves or dangerous chemicals. Always ask an adult for help with difficult chores.
Benefits: A teamwork approach makes home life happier, teaches skills and builds good habits for the future.
Key Point: Help + Respect = Good Neighbour
Neighbours are the people who live near your home — in the same house, next door, in the same building, or on the same street. In the chapter "Chhotu’s House" Chhotu meets and learns about the people living around him. Neighbours can help each other, share things, and make a neighbourhood friendly and safe.
A community is a group of people who live in the same area and use common places like schools, markets, parks and clinics. A community includes families, shopkeepers, teachers, doctors, sanitation workers, policemen and many others. Everyone in a community has roles that help the area run smoothly.
Follow simple rules like not playing on the road, using dustbins, crossing roads safely, and listening to parents and teachers. For safety, know your house address, a trusted neighbour's number, and how to get help from community helpers like the doctor or policeman.
Key Point: Total animals = Number of pets + Number of domestic animals + Number of visiting animals + Number of insects/pests
Animals Around the House
Animals that live in or visit our house and its surroundings are called animals around the house. These include pets (for example, dog, cat, parrot), domestic animals kept near the home (cow, buffalo, goat, hen), wild or visiting animals that come close to houses (sparrows, squirrels, frogs), and small creatures and insects (ants, houseflies, mosquitoes, rats).
Types and where they live
What they eat
How they help us
How they may harm us and safety measures
How to care for animals
Observing animals around the house helps children learn about different kinds of animals, their needs, and how people and animals can live together safely and happily.
Key Point: OBSERVE = Sight + Sound + Smell + Touch (+ Taste when safe) — use all senses where appropriate
What are Observational Skills?
Observational skills are the ability to notice and remember details using your five senses — sight, hearing, smell, touch and (sometimes) taste. In the chapter "Chhotu’s House," observational skills help children look carefully at rooms, objects and actions in the house to understand and describe them.
What are Language Skills?
Language skills are the abilities to name things, form sentences, describe what is seen or heard, ask and answer questions, and tell short stories. In Class 3 these include using simple nouns, verbs and adjectives, making short sentences, and asking the 5Ws and 1H (Who, What, When, Where, Why, How).
How the two work together
First you observe (see details, notice sounds, smell, textures). Then you use language to describe what you saw, to ask questions and to tell others. Good observation gives rich material for speaking and writing clear sentences.

Benefits for students
Improves attention, vocabulary, sentence formation, listening skills and the ability to speak clearly about real-life things. These are foundational for reading, writing and science observations later on.
Key Point: Average temperature for a period = (T1 + T2 + ... + Tn) / n — where T1..Tn are daily temperatures
Climate vs Weather (simple): Weather is what happens on a single day (sunny, rainy, windy). Climate is the usual pattern of weather in a place over many years (for example, hot summers and heavy monsoons).
Seasons: Many places have different seasons such as summer, monsoon (rainy) and winter. Each season brings changes in temperature, rainfall, plants, animals, clothing and houses.
How seasons and climate cause differences:
Why these differences matter: Knowing how climate and seasons change things helps us plan—what clothes to buy, how to build houses, when to plant crops and how to protect animals and plants.
