Definition

What is it?

Tallest refers to the object or person that has the greatest height among a group. It means reaching the highest point upwards from the ground. We use 'tallest' to compare heights.

Simple Example

Quick Example

Imagine you have three friends: Rohan, Priya, and Amit. If Rohan is 150 cm tall, Priya is 145 cm tall, and Amit is 155 cm tall, then Amit is the tallest among them because 155 cm is the greatest height.

Worked Example

Step-by-Step

Let's find the tallest building in a small city. We have three buildings:
Building A: 25 meters tall
Building B: 30 meters tall
Building C: 28 meters tall
---
Step 1: List the heights of all the buildings. Building A = 25m, Building B = 30m, Building C = 28m.
---
Step 2: Compare the heights. Start by comparing Building A and Building B. 30 meters (Building B) is greater than 25 meters (Building A).
---
Step 3: Now compare the taller one (Building B) with the remaining building (Building C). 30 meters (Building B) is greater than 28 meters (Building C).
---
Step 4: Since Building B has the greatest height of 30 meters, it is the tallest.
---
Answer: Building B is the tallest.

Why It Matters

Understanding 'tallest' helps us compare and organize things by height, which is important in many fields. Architects use it to design skyscrapers, and civil engineers need it to plan bridges. Even sports coaches use it to pick players for positions where height matters, like in basketball!

Common Mistakes

MISTAKE: Confusing tallest with widest or longest. | CORRECTION: Tallest specifically refers to vertical height (upwards), not width or length.

MISTAKE: Not comparing all items in a group before deciding. | CORRECTION: To find the tallest, you must compare the height of every single item or person in the given group.

MISTAKE: Using 'tallest' for objects that are very short. | CORRECTION: 'Tallest' is used when comparing things that have a noticeable height. For very short objects, we might say 'highest' if comparing their top point, but 'tallest' implies significant vertical dimension.

Practice Questions

Try It Yourself

QUESTION: A tree is 10 meters tall, a lamp post is 4 meters tall, and a pole is 7 meters tall. Which is the tallest? | ANSWER: The tree is the tallest.

QUESTION: In a family, Papa is 175 cm, Mummy is 160 cm, and their son Raj is 140 cm. Their daughter Rina is 155 cm. Who is the tallest in the family? | ANSWER: Papa is the tallest (175 cm).

QUESTION: You have four stacks of books. Stack 1 is 35 cm, Stack 2 is 42 cm, Stack 3 is 38 cm, and Stack 4 is 45 cm. If you remove 5 cm from the tallest stack, which stack becomes the tallest then? | ANSWER: Stack 2 becomes the tallest (42 cm) because Stack 4 (45-5 = 40 cm) would no longer be the tallest.

MCQ

Quick Quiz

Which of these objects is most likely to be described as 'tallest'?

A small pebble

A skyscraper

A flat road

A wide river

The Correct Answer Is:

A skyscraper is a very tall building, so 'tallest' is a suitable descriptor for it when comparing buildings. Pebbles, roads, and rivers are not typically described by their 'tallness'.

Real World Connection

In the Real World

When you see news about India's tallest statue, the 'Statue of Unity' in Gujarat, or the tallest residential building in Mumbai, they are all examples of comparing heights. Civil engineers and construction workers use this concept daily to ensure structures meet specific height requirements and to identify record-breaking constructions.

Key Vocabulary

Key Terms

HEIGHT: The measurement from bottom to top | COMPARE: To look at two or more things to see how they are similar or different | VERTICAL: Going straight up or down | GREATEST: The largest in amount or size

What to Learn Next

Now that you understand 'tallest', you can explore 'shortest' to compare items by their smallest height. You can also learn about 'longest' and 'widest' to compare objects based on other dimensions, which are important in geometry!
