Compare lengths using words: long, short, tall, taller, shorter.
Compare weights using words: heavy, light, heavier, lighter.
Measure length using non-standard units like hand spans, pencils, and steps.
Understand why we need standard units of measurement.
📖 Let Us Begin!
Ravi wants to know if his pencil is longer than Meena's pencil. He places them side by side and sees that his pencil is longer. We compare things every day! We compare how long, how tall, or how heavy things are. Let us learn about measurement.
Comparing Lengths
We use words like long, short, tall, taller, shorter, longer to compare lengths.
Example:
A bus is longer than a car.
A tree is taller than a plant.
A pencil is shorter than a ruler.
To compare, place objects side by side with one end lined up.
Comparing Weights
We use words like heavy, light, heavier, lighter to compare weights.
Example:
A stone is heavier than a feather.
A bag of rice is heavier than a bag of cotton.
A book is lighter than a brick.
Measuring with Non-Standard Units
Before rulers were invented, people used their hands, feet, and other objects to measure. We call these non-standard units.
Example: Sita measured her desk using her hand span. The desk was 8 hand spans long.
Arjun measured the classroom using his steps. It was 12 steps long.
Why do we need standard units? Because everyone's hand span is different! A standard unit like a centimetre is the same for everyone.
📝 Key Words

Compare
To look at two things and see which is more or less
⭐ Key Points to Remember
Long and short describe length. Tall and short describe height.
Heavy and light describe weight.
To compare lengths, place objects side by side with one end lined up.
Non-standard units (hand span, pencil) can be used to measure.
Standard units like centimetres are the same for everyone.
