Class 3 Maths - PUNJAB
Filling and Lifting
The chapter Filling and Lifting in Class 3 Mathematics introduces young learners to the basic concepts of capacity and measurement of liquids. Students will explore how different vessels hold different amounts of water, milk, or juice using standard and non-standard units like litres and millilitres. Through fun activities and real-life examples, children learn to compare containers by their capacity and understand which holds more or less. This foundational topic is very important for the Punjab PSEB board exams as it builds essential math skills required for everyday life measurement problems and scoring steady marks in primary school assessments.

Capacity
Capacity is the maximum amount of liquid that a container can hold.
Litres (l)
Litres are the standard unit used to measure larger quantities of liquids, such as a bucket of water or a large bottle of milk.
Millilitres (ml)
Millilitres are used to measure smaller quantities of liquids, like medicine in a spoon or ink in a pen.
Comparison of Capacity
Comparing different vessels to find out which one holds more liquid and which one holds less using direct observation or measuring tools.
Estimation
Guessing the approximate amount of liquid a container can hold before actually measuring it.

Frequently Asked Questions
What is the difference between litres and millilitres?
Litres are used for measuring large amounts of liquids like water in a tank, while millilitres are used for small amounts like cough syrup in a spoon.
How many millilitres make one litre?
One litre is equal to 1000 millilitres (1 l = 1000 ml).
How do we measure the capacity of a water bottle?
We measure the capacity of a water bottle using litres or millilitres, depending on the size of the bottle, by seeing how much water it can hold.
