What the chapter is about
Nandita's visit to Mumbai describes her experience of going from a smaller place (home/village/town) to a big city. The chapter highlights the differences between village/town life and city life: the crowd and noise, tall buildings and narrow lanes, different modes of transport, busy markets, many kinds of jobs, and how people live close together in small houses or flats. Through Nandita's eyes we learn about how cities work and what makes them different.
Main points to remember
What students should be able to do after reading
Describe one city visit, name different vehicles and shops seen, explain why cities are crowded, and suggest simple ways to keep a city clean and safe.
Key Point: Speed = Distance ÷ Time (Example: If a bus covers 30 km in 1.5 hours, speed = 30 ÷ 1.5 = 20 km/h)
What the topic is about
Travel and transport means the ways people and goods move from one place to another. In the chapter ‘Nandita in Mumbai’, Nandita uses different modes of transport (walking, buses, trains, rickshaws, taxis, etc.) to move around the city. The chapter shows how each mode is useful in different situations and why transport is important for work, school, markets and visiting places.
Types of transport
There are two main kinds: walking (no vehicle), non-motorised (bicycle, hand-pulled rickshaw), and motorised (bus, car, train, auto-rickshaw, taxi, boat). Transport can also be public (bus, train) or private (car, bicycle).
Why transport is important
It helps us reach school, hospitals, markets and friends. Good transport saves time, connects people and supports business. But transport also affects the environment: motor vehicles cause noise and air pollution and traffic jams.
Choosing the right transport
When choosing how to travel, we think about time, cost, comfort, safety and pollution. For short distances, walking or cycling is healthy and clean. For long distances or when many people travel together, public transport (buses, trains) is usually better.
Safety and rules
Always follow traffic rules: use zebra crossings, traffic signals, wear seat belts in cars and helmets on two-wheelers, do not stand near train doors, and let older people and children sit on public transport. These rules keep travel safe for everyone.
Key Point: Area of a rectangular room = length × width (useful to find carpet or paint area). Example: a 4 m × 3 m room has area 4 × 3 = 12 m².
City landscape means the view and layout of a town or city — the roads, open spaces, parks, markets, water bodies and the buildings you see. In the story "Nandita in Mumbai", Nandita notices many things: tall buildings, row houses, busy markets, trains, crowded streets and the sea by the shore. Cities like Mumbai have different types of buildings and places close to one another.
Types of buildings and places you find in a city:
Features of city buildings and landscape:
Safety and environment: Buildings should be strong and safe. Open spaces and trees make the city healthier. Cities can be noisy and polluted, so spreading parks and using public transport help reduce problems.
How children like Nandita learn from the city: By observing different buildings, counting floors, noticing shops and parks, and understanding how people use each place.
Key Point: Total cost = Unit price × Quantity (useful when buying groceries).
Introduction
The chapter “Nandita in Mumbai” shows how different people and their jobs shape daily life in a city. People do many types of work — paid and unpaid — and these jobs provide services and goods that everyone uses. The story of Nandita helps us notice the variety of occupations, how families organize their day, and how people depend on one another.

Key Point: Total cost = (price per unit) × (number of units). Example: cost of 3 kg sugar at Rs. 40/kg = 40 × 3 = Rs. 120.
This topic explains how markets and shops work and how they provide food for families in a city like Mumbai. A market is a place where people buy and sell things. Shops are small or large places inside or outside the market that sell particular items — for example, a vegetable stall, a kirana (grocery) shop, a bakery, a fish stall, a sweet shop, or a supermarket.
Types of shops and stalls:
How food reaches the market (simple flow):
Buying smart and safely:
Everyday money and measurement ideas (practical): use simple multiplication and addition when buying several items; know weight units like grams and kilograms (1 kg = 1000 g). In Mumbai, you can see both bargaining in open markets (Crawford Market-style) and fixed-price retail in supermarkets.
Food and the environment: using reusable bags, avoiding plastic where possible, and buying local produce reduce waste and help the environment.
Key Point: Population density = Population / Area (people per square kilometre or per square metre). Useful to compare how crowded two places are.
What is a slum? A slum is a crowded area in a city where many families live in small, temporary or poorly built houses. These places often lack clean water, toilets, proper drainage, safe electricity and enough space. In the story "Nandita in Mumbai" we see a contrast between tall apartment buildings and close-packed slum houses. This helps us understand how people live in different ways in the same city.
Why do slums form? Slums form because many people move from villages to cities looking for jobs and better life. Cities may not have enough cheap houses for everyone, so people build small homes on empty land, near railway tracks or rivers. Poverty, lack of affordable housing, and fast city growth are main reasons.
What are the living conditions? Common problems in slums are overcrowding (many people in one room), no running water or water from a public tap, few or no toilets (leading to open defecation), poor drainage and toilets that cause dirty water to stand, unsafe or no electricity, and little access to schools and health clinics. These conditions can make people sick and make it hard for children to study.
Effects on children and families Children may get sick often, miss school, or have to work to help their families. Families may lose time and money caring for illnesses. Poor sanitation spreads illnesses like diarrhea, which is dangerous for young children.
How can slums improve? Improvements can come from the government building low-cost houses, providing clean water and toilets, NGOs helping with health and schools, and community actions (clean-up drives, saving groups). Simple steps like building community toilets, fixing drains, and setting up small local schools make a big difference.
What can we do as students? Learn about different lives, help with awareness campaigns, collect clothes or books for children in need, keep our neighbourhood clean, and treat everyone with respect and kindness. Small actions and caring attitudes help change lives.
Key Point: Population density = Total population ÷ Area (people per square kilometre). Example: If 10,000 people live in a 2 km² area, density = 10,000 ÷ 2 = 5,000 people/km².
What is an urban area? An urban area is a city or town where many people live and work close together. Cities like Mumbai are busy places with tall buildings, roads, trains and markets.

Short story link to Nandita in Mumbai (class example)
Nandita visits Mumbai and sees crowded trains, busy roads and piles of garbage near some houses. She learns that many people come to the city to find work. She and her friends start small changes — using dustbins, planting a sapling, and encouraging their neighbors to save water. These small steps help make the place cleaner and healthier.
Key Point: Population density = Population ÷ Area (people per sq. unit) — shows how crowded a place is.
This topic compares life in a village and life in a city in simple terms suitable for Class 4. A village is a small settlement with open spaces, farms, and fewer buildings. A city is a large settlement with many people, tall buildings, and busy roads.
Key Point: Look-Left-Right-Left = Safe to cross (simple road-crossing rule for children).
Living in a city like Mumbai means walking on busy streets, using buses and local trains, visiting markets and parks, and meeting many people. Children must learn simple safety rules and good manners so they can move around safely and respectfully.

Summary: By following simple safety rules and good manners — looking both ways before crossing, using polite words, not littering and staying alert — children can enjoy the city safely and help make it a better place for everyone.
Key Point: Three R’s: Reduce + Reuse + Recycle = Less waste sent to landfill
What is the environment? The environment is everything around us — air, water, plants, animals, buildings and people. A healthy environment keeps us fit and happy.
Why is cleanliness important? Cleanliness helps prevent diseases, keeps our neighbourhood attractive, protects animals and keeps water and air safe. Dirty places collect germs, attract flies and mosquitoes, and make people sick.
What is civic responsibility? Civic responsibility means the duties each person has towards the community: following rules, keeping public places clean, respecting others, and helping look after shared resources like parks, drains and roads.
How can children help? Children can: throw waste in dustbins, separate wet and dry waste, avoid single-use plastic, save water and electricity, plant trees, use public transport or walk when possible, not vandalize walls, and tell adults about blocked drains or overflowing bins. Small actions by many people make a big difference.
Connection to 'Nandita in Mumbai' In the story, Nandita sees how a big city works and learns that every person — including children — can help keep the city clean.

Key Point: Empathy = Notice + Listen + Imagine + Respond
What are values? Values are ideas and beliefs that help us decide what is right and wrong. They guide our behavior — for example, honesty, kindness, respect and responsibility are values we practice at home, school and in society.
What is empathy? Empathy means understanding how another person feels and trying to imagine their situation. It is different from just feeling sorry: empathy involves listening, putting yourself in someone else’s place, and responding with care.
Why are values and empathy important? Values build good character and help a community live peacefully. Empathy helps us form friendships, resolve conflicts, and support people who are sad, scared or in need. Together they make classmates, families and neighbourhoods kinder and safer.
