Filling and Lifting Class 3 Maths Chapter 11 CBSE Notes 2025-26

Understanding how much objects can hold and weigh is very useful in everyday life. In Chapter 11 of Class 3 Maths – “Filling and Lifting” – students get to explore the ideas of measuring, comparing, and estimating the volume and weight of different things using simple tools and daily objects. This chapter focuses on hands-on activities and logical reasoning, helping children relate math to the real world.

Imagine two different sized glasses: one big, one small. If someone challenges you to drink six full glasses of juice, but doesn’t mention the size, would you accept? Chintu refuses such a challenge because he realizes a bigger glass holds much more than a small one. So, the number of glasses doesn’t always mean more quantity – the size matters! This teaches us to be careful when comparing amounts, and not just count how many glasses or cups, but notice how much each holds.

Children are encouraged to observe and guess which glass among their friends (Ritu, Monu, and Nita) holds the most milk. The way to check is by pouring the contents into identical glasses and comparing the levels. Sometimes, the biggest looking glass is not the one with the most in it! Students discuss who drank the most or least milk and compare their glasses and vessels at home in a similar manner.

• Try using three different vessels (like a bowl, glass, and bottle) at home and guess how many of one will fill the other. Then verify by actually pouring and counting.
• Fill in statements like: “Nita’s glass holds ___ milk than Monu’s.”
• Identify which vessel at home can store more water than your bottle.

This chapter encourages kids to use common utensils—like ladles, bowls, glasses, and jugs—to measure and compare quantities. Instead of always using standard units, kids learn estimation and counting how many small vessels are needed to fill a big one, or how many glasses a jug can fill. Through repeated pouring, they see that a large container can be filled by several small ones and vice versa. It’s a fun way to understand that total quantity remains the same even if the vessels used are different.

1. Estimate how many ladles fill a bowl and check your answer.
2. Count the glasses filled from a jug or lemonade pot.
3. Discuss why using a bowl or ladle might be easier in some situations.

Students are also guided to figure out which utensils are better for sharing drinks—such as using a ladle or jug for pouring lemonade equally.

The chapter introduces the idea of litre as a standard unit. Nita’s 1-litre bottle helps compare and check which vessels at home can hold more, less, or exactly 1 litre. Students tick statements such as “the glass holds less than 1 litre” or “the jug holds exactly 1 litre.” Observing the milkman using a measuring cup at home brings real-world maths into focus. Children are encouraged to measure, guess, and discuss which everyday vessels are 1 litre, half-litre, or quarter-litre.

• Find vessels at home that hold exactly 1 litre and compare to others.
• Use actual measuring bottles or cups to check your guesses.

Kids realize that four quarter-litre glasses equal one litre, and two half-litre mugs also make one litre. They use these insights to compare buckets, mugs, and glasses at home—"Is a bucket more than 1 litre? Is a glass less than a quarter litre?"

Children learn about comparing weights by using both hands or by using simple balances. For example, Chintu holds textbooks in one hand and a pencil box in the other and notices his hand with the textbooks goes down—it’s heavier! Students can try this themselves with everyday things like lunch boxes, pencil boxes, apples, watermelons, balloons, or basketballs, and note which is heavier.

An interesting fact: making a 1-litre plastic bottle actually uses about 5 litres of water, so using reusable bottles helps save water!

Children get to make their own balancing weights by using coins or erasers. They balance objects like pencils or ping pong balls on one side and count how many coins or erasers are needed to balance them. For slightly heavier things, they use a matchbox filled with sand.

After balancing, children can list the objects from lightest to heaviest. This activity develops observation skills and estimating weights.

The next topic is about a kilogram, half-kilogram, and quarter-kilogram. Children are guided to find packets at home (like salt, dal, or tea) that weigh 1 kg, ½ kg, or ¼ kg. They then guess and verify which objects are heavier or lighter than a kilogram. Activities ask students to count the books in their bags and compare weights with their friends, or even adjust the number of books so two bags balance.

• Write a list of objects at home that weigh exactly 1 kg, half kg, or quarter kg.
• Tick which objects are more or less than 1 kg in a simple table provided in the book.
• Practice comparing packet weights and identify similarities and differences.

Students learn that, for example, each dal packet weighs either half a kg or a full kg, and a tea packet might be half, quarter, or a whole kilogram. They use pan-balances, observation, and discussion to develop a keen understanding of weight comparison.

As a fun challenge, students are given three balls that look the same size but have different weights. Using just a pan-balance (and the balls themselves—no extra weights), the challenge is to spot the ball that is heavier or lighter, sometimes with just one weighing. This tests reasoning, logical thinking, and understanding of balance as a tool for comparing weights.

All these activities together help children build practical understanding about measurement—both volume and weight—using things in their environment. The focus is not just memorizing units, but actually observing, doing, discussing, and thinking about everyday maths.
