What is Measurement?

  • Look around! Some things are long, like a skipping rope, while others are short, like a pencil. Some objects hold a little water, like a teacup, while others hold a lot, like a big water bottle.
  • We use measurement to find out how long, tall, heavy, or full something is. When we measure, we can compare—Is the table longer than the bed? Does a bucket hold more water than a mug?
  • Let’s explore measurement and learn how we can compare length, distance, and capacity in fun ways!

Comparing Lengths

Measuring Length

Measurement Class 1 Notes Maths Chapter 7Mohit and Meeta place their pencils along the edge of the tabletop to measure the length of the table.

Mohit: The length of the table is the same as 10 pencils.
Meeta: The length of the table is the same as 14 pencils.
Their measurement is different because Meeta's pencil is shorter than Mohit's pencil.
For correct measurement, Mohit and Meeta both should have used pencils of the same length.

Edurev Tips: If two people measure the length of the same object using the same ‘standard length’, their measurement will be the same or nearly same.

Measuring Length Using Body Parts


Long ago, people used to measure the length or height of objects using their body parts.
Some body parts that are used as units of length are shown below:

FAQs on Measurement Class 1 Notes Maths Chapter 7

1. How do you compare lengths?
Ans. To compare lengths, you can use a measuring tool such as a ruler or a tape measure. Place the measuring tool next to the objects you want to compare and align the starting points. Then, read the measurements on the tool to determine which length is greater or smaller.
2. What are the units used for measuring length?
Ans. The units commonly used for measuring length are centimeters (cm), meters (m), and kilometers (km). Centimeters are typically used for smaller objects, meters for medium-sized objects, and kilometers for larger distances.
3. How do you measure mass or weight?
Ans. To measure mass or weight, you can use a weighing scale. Place the object you want to measure on the scale and wait for it to stabilize. The scale will display the measurement in units such as grams (g) or kilograms (kg), indicating the mass or weight of the object.
4. How can you compare capacities?
Ans. Comparing capacities involves comparing the volume or amount of liquid that different containers can hold. You can pour the liquid into each container and observe how much each container can hold. To compare accurately, it is important to use containers with the same shape and size.
5. What units are used for measuring capacity?
