01. What’s in a Name?- Chapter Notes

Introduction

Imagine you have a big jar of candies and you really want to know exactly how many are inside. What would you do?

That’s where counting comes in—a superpower that helps you keep track of everything!

Now, let’s meet two brothers who used counting in a very smart way.

A Cow Story: Deba and Deep Learn to Count

Long ago, in a village, two brothers named Deba and Deep looked after cows. Every day, they took the cows out for grazing and brought them back in the evening.

  • One day, Deba asked, “How do we know if all cows have come back?”
  • Their friend suggested, “Make a mark on the wall for each cow when it leaves. When it returns, strike the mark. If all marks are gone, all cows are back!”
  • Next day, they tried it. And it worked! From that day, they always used counting marks to keep their cows safe.

What Happened Later?

  • As years passed, Deba and Deep had more cows. One day, before leaving, they made marks on the wall for each cow. When they came back, they started striking out the marks as each cow entered the gate.

Marks on the wall that represent the number of cows

  • But two marks were still left! And no cows were outside!
  • Why were they worried? Because this meant two cows were missing!
  • They quickly went to search and found the missing cows nearby. Thanks to their counting trick, they saved their cows.
  • Counting saved the day!

Why Counting Is Important

  • To Know How Many: Counting tells us how many toys, sweets, or books we have.
  • To Share Fairly: You can count your candies to share them equally with your friends.
  • To Solve Problems: Lost something? Count what you have to know what’s missing.
  • To Make Plans: If your birthday is in 5 days, you can plan something for each day!

Let’s Count Letters in Names!Let’s take the name “Samantha”.

  • Write it out: S-A-M-A-N-T-H-A
  • Count each letter: That’s 8 letters!

Now try your own name. How many letters?

You can also:

  • Find names that start with the same letter.
  • Check which letter is used the most.
  • Find the shortest and longest names in your class!

Try yourself:How many letters are there in the word “MATHEMATICS”?

  • A.11
  • B.5
  • C.3
  • D.4

  • Richa and Ayushi were sisters. One day, they argued.
  • “My name is bigger!” said Richa. “No! Mine is!” replied Ayushi.
  • Their brother Rahul said, “Let’s count the letters.”

  • Richa: R-I-C-H-A = 5 letters

    Ayushi: A-Y-U-S-H-I = 6 letters

  • Ayushi’s name was longer! They laughed and made up. Counting helped them solve the argument.

So, counting isn’t just about numbers. It’s a way to explore, learn, and solve problems, just like Richa and Ayushi did!

Counting in Number Names

Let’s try the number “Seven”.

  • S-E-V-E-N = 5 letters
    Try with other numbers:
  • Three = 5 letters
  • Eleven = 6 letters
  • Twenty = 6 letters

Number names are words for numbers. Instead of 1, we say “One”. 
Below are the number names for the first few natural numbers:

Let’s Practice with Number Friends!

In the land of Numerica, friends Eighty-Nine, Ninety, and Ninety-One wanted to see who had the longest name.
Let’s count the letters in their names to see who has the biggest name!

  • “Eighty-Nine” = 10 letters
  • “Ninety” = 6 letters

  • “Ninety-One” = 9 letters

Eighty-Nine had the longest name! But they all learned counting and had fun together.

The friends celebrated their newfound knowledge and friendship, knowing that each of their names was special in its own way.

Just like this, we can count the letters in all the numbers’ names and other words as well. Keep practicing, and you’ll become a pro at counting letters in no time!
