Introduction to NCERT Class 3 Maths Chapter 11 Filling and Lifting

Book: Maths Mela, the NCERT Mathematics textbook for Class 3 (Grade 3). Chapter: 11, Filling and Lifting. Board: CBSE and other schools that follow NCERT. This chapter has two big ideas. Filling is about capacity, which means how much a vessel can hold. Lifting is about weight, which means how heavy or light something is. Children compare vessels by pouring, learn the litre with its half and quarter, compare weights by feeling and with a pan balance, and learn the kilogram with its half and quarter.

What is there in the chapter?

• A juice challenge that shows a bigger glass needs fewer glasses to drink the same juice
• Comparing milk in glasses of different shapes by pouring it into three glasses of the same size
• Guessing how many small bowls fill a glass and how many glasses fill a bottle, then checking by pouring
• Filling a bowl with ladles and glasses with a jug, and sharing lemonade
• Why milkmen use a measuring cup, and the 1 litre bottle
• Deciding if a vessel holds more than, less than or exactly 1 litre, and a half litre and a quarter litre
• Holding things to feel which is heavier and which is lighter
• Weighing with coins, erasers and a matchbox filled with sand on a pan balance
• A weight hunt for school bags, and finding things that are 1 kilogram
• Half kilogram and quarter kilogram packets
• Tricky balls: finding the heavy ball among 3, and finding the heaviest and lightest among 3 balls

NCERT Class 3 learning objectives for this chapter

These objectives are written from the content of the chapter. They are not copied from the book.

• To compare how much two or more vessels hold, using pouring

• To know the litre as a unit for liquids and to use half litre and quarter litre
• To compare weights by holding and with a pan balance
• To weigh with simple units such as erasers, coins and a matchbox
• To know the kilogram as a unit of weight and to use half kilogram and quarter kilogram
• To use reasoning to find a heavy ball with a pan balance

What is Class 3 Maths Chapter 11 Filling and Lifting?

Chapter 11 of the NCERT Class 3 Maths book Maths Mela is called Filling and Lifting. It is about capacity and weight. Capacity is how much a vessel can hold and it is measured in litres. Weight is how heavy something is and it is measured in kilograms. Children first compare by looking, pouring and holding, and then use standard units.

Which glass holds more?

Glasses come in different shapes, so it is hard to tell by looking which holds more. To compare, pour the milk from each glass into glasses of the same size. The one with the highest level holds the most milk. The one with the lowest level holds the least. The same idea works for finding how many small bowls fill a glass. First guess, then pour and count.

Bigger vessel, fewer pours

In the juice challenge a child can drink 6 small glasses but not 6 big glasses. A bigger glass holds more juice, so fewer glasses are needed for the same amount. A smaller vessel needs more pours. A ladle needs many pours to fill a glass and a glass needs many pours to fill a jug. In both cases the amount of water stays the same. If one jug fills 6 glasses then 3 jugs fill 6 + 6 + 6 = 18 glasses.

The litre

A milkman pours milk with a measuring cup that holds 1 litre. The litre is a standard unit for liquids, so everyone gets the same amount. A 1 litre bottle can be used to find out how much other vessels hold. A glass holds less than 1 litre. A bucket holds more than 1 litre. A jug that holds exactly 1 litre fills the 1 litre bottle exactly.

Half litre and quarter litre

A half litre is half of 1 litre. A quarter litre is half of a half litre, so it is one fourth of a litre. 2 half litres make 1 litre. 4 quarter litres make 1 litre. 2 quarter litres make a half litre. A mug may hold a half litre and a glass may hold a quarter litre.

Heavy or light?

A child holds 3 textbooks in one hand and a pencil box in the other. The hand with the books goes lower because the books are heavier. To compare two things, hold them in both hands or place them on the two pans of a pan balance. The pan of the heavier thing goes down. If both pans stay level the two things weigh the same.

Weighing with erasers, coins and a matchbox

With a pan balance we can weigh by counting how many coins or erasers balance an object. A pencil may balance 3 erasers and a spoon may balance 5. The object that needs more erasers is heavier. For slightly heavier objects a matchbox filled with sand makes a bigger weight. Children guess how many matchboxes an object needs, then check. They then list the objects from the lightest to the heaviest.

The kilogram, half kilogram and quarter kilogram

The kilogram is the standard unit for weight. Many packets of salt, sugar or flour at home have 1 kg written on them. Holding a 1 kilogram packet helps us guess which things are heavier or lighter than 1 kilogram. Half a kilogram is half of 1 kilogram and a quarter kilogram is half of a half kilogram. 2 half kilograms make 1 kilogram and 4 quarter kilograms make 1 kilogram. On a balance, two half kilogram packets of dal balance a 1 kilogram packet.

Tricky balls

There are 3 balls that look the same. One is heavier and the other two weigh the same. You can find the heavy ball with only one weighing. Put one ball on each pan and keep the third ball out. If the pans stay level, the ball left out is heavy. If one pan goes down, the ball on that pan is heavy. In another puzzle there are 3 balls of different weights, red, orange and green. Weigh two of them, then weigh the heavier one against the third ball, to find the heaviest and the lightest.

Types of questions to practise

Questions on this chapter ask children to pick the glass that holds the most or the least, count pours, say if a vessel holds more or less than 1 litre, use half litre and quarter litre, read a pan balance, count erasers, use kilograms and solve ball puzzles. The online quiz on this page mixes choice questions, true or false questions, picture questions and typed answers, and the practice sheet has 16 typed answers.

Solved examples

Common mistakes

Capacity and weight in daily life

We use litres for milk, oil, water and juice and kilograms for rice, sugar, vegetables and fruit. Ask your child to find a 1 litre bottle and a 1 kilogram packet at home. Ask which things in the kitchen hold more than 1 litre, which weigh less than 1 kilogram and how many glasses a jug of juice can fill.

What your child learns from the Filling and Lifting worksheet

• Comparing how much vessels hold
• Counting pours with bigger and smaller vessels
• The litre, half litre and quarter litre
• Comparing weights with a pan balance
• Weighing with erasers and coins
• The kilogram, half kilogram and quarter kilogram
• Reasoning with the tricky balls puzzle
• Choosing the right unit for liquids and for weight

Tips for parents and teachers

Let your child pour water between a small bowl, a glass and a bottle and guess before pouring. Mark a 1 litre bottle and see how many glasses it fills. Make a simple balance with a ruler and two cups and weigh small things against erasers. Keep a 1 kilogram packet of salt for your child to hold and compare. Play the three balls puzzle with real balls.
