Introduction to Measurements for Class 1 Students: Definition, Characteristics and Examples

Measurements for Class 1 introduces young learners to the basic idea that we can compare and describe objects using simple attributes like length, weight, and capacity. This short introduction uses everyday examples like measuring a pencil with paper strips, comparing which bag is heavier, or pouring water into cups so children understand measurement as a way of finding “how much” or “how long” in familiar situations. The guide focuses on simple explanations, relatable examples, and clear illustrations to help students understand measurement concepts while building early measurement vocabulary and number sense.

Measuring Length

Measuring length helps us find out how long or short an object is. We compare the lengths of different objects and use measurement units to describe their size.

Measuring Length Using Body Parts

The length of an object tells us how long the object is. Before we had rulers and measuring tapes, people used different parts of their body to measure things.

🖐️ Handspan

Width of your open palm from little finger to thumb. 

Example: The ruler is 2 handspans long

💪 Cubit

From your elbow to the tip of your middle finger. 

Example: The table is 3 cubits long

👣 Footspan

The length of your foot from heel to toe. 

Example: The room is 10 footspan long.

NOTE: If Rohan and his teacher both measure the same desk using their handspans, will they get the same number? No. Because everyone's hands are different sizes. A teacher's handspan is bigger than a child's handspan. That's why the same desk might be 6 handspans for Rohan but only 4 handspans for his teacher. This is exactly why we eventually move to standard units like centimetres.

Measuring Length Using Everyday Objects

We can also measure length using small objects we find around us. We line them up one after the other without any gaps or overlaps and then count how many we used. Since this method isn't perfectly precise, we use the word ‘about’ when we describe the length.

Example: This pencil is about 8 paper clips long.

Example: The pencil box is about 4 crayons long.

Comparing by Length

Once we know how to measure length, we can compare two objects. The object with more length is the longer or taller one. The object with less length is the shorter one.

Words We Use to Compare Length

• longer

• shorter

• taller

• the same length

• longest

• shortest

• tallest

• equal

Example: A boy is 3 cubits tall and his father is 5 cubits tall. The boy is shorter than his father. The father is taller than the boy.

Example: A red pencil is 7 paper clips long and a yellow pencil is 4 paper clips long. The red pencil is longer than the yellow pencil.

Comparing by Weight

The weight of an object tells us how heavy or light it is. In Class 1, we compare the weights of objects using a balance.

How to Read a Balance

When we place two objects on a balance:

⬇️ The heavier side goes DOWN

⬆️ The lighter side goes UP

↔️ If both sides are level, the objects weigh the same

Example: A mango is heavier than a strawberry

Words We Use to Compare Weight

• heavier than

• lighter than

• equal weight

• heaviest

• lightest

• same weight

Comparing by Capacity and Volume

Capacity: How Much Can It Hold?

Capacity is the maximum amount that a container can hold. A bucket can hold more water than a glass, so the bucket has more capacity than the glass.

Example: A glass has less capacity than a bucket. It holds less water.

Volume: How Much Space Does It Take Up?

Volume is the amount of space taken up by an object. A bigger object takes up more space and has a greater volume. A smaller object takes up less space and has less volume.

Example: Watermelon has greater volume than an apple; therefore,  it takes up more space

Words We Use for Capacity & Volume

• more capacity

• less capacity

• holds more

• holds less

• greater volume

• less volume

• same capacity

• takes up more space
