Class 3 Maths - KERALA
Filling and Lifting
The chapter 'Filling and Lifting' in Class 3 Mathematics introduced by the Kerala SCERT syllabus helps young learners understand the practical concepts of capacity, volume, and measurement of liquids. Students explore how different vessels like pots, bottles, and buckets hold varying amounts of water. They learn to compare quantities using non-standard units and later move on to standard units like litres and millilitres. This chapter forms the foundation for advanced measurement topics in later classes. In board exams and school assessments, questions from this chapter are crucial for testing basic arithmetic and practical life skills related to liquid measurement.

Capacity
Capacity is the total amount of liquid that a container can hold when it is completely full.
Comparing Volumes
We can find out which vessel holds more liquid by pouring water from one container to another.
Standard Units (Litre)
Litre is the standard unit used to measure larger quantities of liquids like milk, water, and oil.
Small Quantities (Millilitre)
Millilitre is used to measure smaller quantities of liquids like cough syrup, ink, or eye drops.
Addition and Subtraction of Capacity
We can add and subtract quantities of liquids just like normal numbers, keeping the unit (litre or millilitre) the same.
