Class 3 Maths - CBSE
Filling and Lifting
The chapter 'Filling and Lifting' introduces Class 3 students to the basic concepts of measurement, specifically focusing on volume and capacity. Children learn how different vessels hold different amounts of liquid and how to compare them using non-standard units like cups, glasses, and jugs, as well as standard units like litres and millilitres. For CBSE board exams, this chapter is very important because it builds the foundational understanding of measurement and real-life problem-solving skills. Students learn to estimate quantities, solve simple word problems involving addition and subtraction of capacities, and understand how to measure liquids accurately.

Capacity
Capacity is the maximum amount of liquid that a container can hold.
Litres and Millilitres
Larger quantities of liquids are measured in litres (l) and smaller quantities are measured in millilitres (ml).
Unit Conversion
1 litre is equal to 1000 millilitres, which helps us convert between the two units.
Estimation
Guessing how much liquid a container can hold before actually measuring it, such as a spoon holding ml and a bucket holding litres.
Addition and Subtraction of Capacity
Adding or subtracting quantities of liquids in litres and millilitres to solve daily life word problems.

Board Exam Info
In CBSE Class 3 Mathematics, measurement chapters typically carry around 5 to 8 marks. Common question types include filling in the blanks with correct units (litres or millilitres), matching containers to their estimated capacities, converting litres to millilitres, and solving simple word problems on adding or subtracting liquid quantities.
Frequently Asked Questions
How do I know whether to use litres or millilitres for an object?
Use millilitres (ml) for small amounts like medicine syrup or a cup of tea, and litres (l) for large amounts like a bucket of water or a car's fuel tank.
How many millilitres make one litre?
1000 millilitres make one complete litre.
How do I solve word problems involving capacity?
Read the question carefully to see if you need to put liquids together (add) or take them away (subtract), and make sure the units are the same before calculating.
