Measurements of Capacity

Measuring of  Capcity for Class 2 Maths

In this learning concept, students will get the idea of the measurement of the capacity of different types of objects. They can also classify that Different vessels/containers have different capacities. For example, a bigger container can hold more than a smaller container.
Also, students can identify capacity by the units.

Students will get a brief concept about:

• The capacity of the vessel/container depends upon the shape
• units of capacity
• The standard unit of capacity
• non-standard unit of capacity

Each concept is explained to class 2 maths students using illustrations, examples, misconceptions, and mind maps. You can assess your learning by solving the two printable worksheets at the pages’ end.
Download the measurement of capacity worksheet for class 2 and check the solutions for the concept of measurement of capacity provided in PDF format.

Capacity: The capacity of a vessel/container is the quantity of liquid or matter it can hold.

Example 1:

• This jug contains some amount of water.

• The glass is fully filled with water.
• We can easily guess that the jug contains more water than the glass.
• That is because the jug is larger than the glass.

Example 2:

• Jug is the biggest vessel so it contains more amount of water than other vessels.
• Cup is the smallest vessel so it contains least amount of water than other vessel.
• Glass will contain amount of water more than cup and less than jug.

Example 3:

• Height of the vessels is same but first vessel is narrow and second one is broad.
• So, capacity of the first vessel is lesser than the second vessel.

Units of Capacity

Non-standard units of the capacity

1. During ancient times, people used to measure capacity of a vessel by another vessel.
   Examples:  There was traditional wooden measuring pot by which people measure the weight of the grains.
   

   But everyone has different shape and size of pot. So, this pot was a non-standard unit of capacity.

2. Suppose a bucket full filled with 9 mugs of water.

   

    

3. A bucket contains 9 mugs of water.

   But if we take bigger mug, bucket will full fill with 6 mugs.

   

    

4. A bucket contains 6 mugs of water.

   So, here mug is the non-standard unit of the capacity of bucket.

5. When we make a tea we use approximate measure of the sugar. For example, some use 2 spoons of sugar, some use 1 spoon of sugar, etc.

   

    

6. Shape and size of the spoon can vary. So, spoon is also non-standard unit of capacity.
