What is it?

When we compare two or more things, 'shorter than' helps us identify which one has less length or height. It means one object or person has a smaller measurement from end to end compared to another.

Simple Example

Quick Example

Imagine you have two pencils. One is a brand new pencil, and the other is a pencil you've used for many days for your homework. The used pencil is 'shorter than' the new pencil because it has less length.

Worked Example

Step-by-Step

Let's compare the height of two friends, Rina and Sonu.
---Step 1: Rina measures her height and finds it is 120 cm.
---Step 2: Sonu measures his height and finds it is 115 cm.
---Step 3: We compare 120 cm and 115 cm.
---Step 4: Since 115 is a smaller number than 120, Sonu's height is less than Rina's height.
---Answer: Sonu is shorter than Rina.

Why It Matters

Understanding 'shorter than' is basic to logic and math, helping us compare quantities and make decisions. It's used by architects to design buildings, by tailors to cut clothes, and even in computer programming to sort data based on size.

Common Mistakes

MISTAKE: Confusing 'shorter than' with 'longer than'. Students might say a small object is 'longer than' a big one. | CORRECTION: Remember 'shorter than' means 'less length', while 'longer than' means 'more length'. Always check which item has the smaller measurement.

MISTAKE: Only thinking about height when comparing 'shorter than'. | CORRECTION: 'Shorter than' applies to any linear measurement, like length of a rope, distance, or even time duration, not just how tall something is.

MISTAKE: Not having a common unit of measurement when comparing. For example, comparing a length in meters with another in centimeters directly. | CORRECTION: Always convert both measurements to the same unit (e.g., both to centimeters or both to meters) before comparing to avoid errors.

QUESTION: A skipping rope is 3 meters long. A cricket bat is 1 meter long. Which item is shorter than the other? | ANSWER: The cricket bat is shorter than the skipping rope.

QUESTION: Your school bus route is 10 km. Your friend's school bus route is 8 km. Whose bus route is shorter? | ANSWER: Your friend's bus route is shorter.

QUESTION: A mobile phone cable is 150 cm long. Another cable for a laptop is 2 meters long. Which cable is shorter? (Hint: 1 meter = 100 cm) | ANSWER: The mobile phone cable (150 cm) is shorter than the laptop cable (200 cm).

MCQ

Quick Quiz

Which of these statements correctly uses 'shorter than'?

A 10-rupee note is shorter than a 50-rupee note.

A 5-minute song is shorter than a 3-minute song.

A 15-cm pencil is shorter than a 20-cm pencil.

A 50 kg bag of rice is shorter than a 20 kg bag of rice.

The Correct Answer Is:

Option C is correct because 15 cm is a smaller length than 20 cm. Options A and D compare value/weight, not length. Option B incorrectly states 5 minutes is shorter than 3 minutes.

Real World Connection

In the Real World

In Indian railways, engineers need to compare track lengths to plan routes. When building a new metro line, they might need to know if the new track section is 'shorter than' an existing one to manage resources efficiently. Even while packing luggage for a train journey, you might choose a bag that is 'shorter than' the storage space available.
