Chapter 1
What's in a 1 Name?
A long long time ago, there was a
cowherd family in Tarakeshwar. Every
day Deba and Deep took the cows out for
grazing. They used to return in the late
evening together with all the cows.
One day, Deba asked: How do we know
that we have not lost any cows? They did
not know how to count.
What could Deba and Deep do?
Their friend gave them an idea: When you
go out, make a mark on the wall for
each cow that leaves the gate. Then
when you come back, strike out one
mark from the wall each time a
cow re-enters the gate.
What's in a 1 Name?
The next day they followed
their friend’s idea, and all the
marks were struck out when
they came back home
Did all the cows come back home?
After a few years, they
had many more cows. One
day, their wall had this
many marks when they left
home.
So, they had .......... cows.
The next day they returned
with the cows. They struck
out one mark as each cow
re-entered the gate. Two marks were still left on the wall but they
didn’t see any cows outside. They were worried.
Why were Deba and Deep worried?
How many cows had reached home? ..............................
Deba and Deep quickly went to search for the missing cows and
found them in a nearby field. They all happily returned home
together!
Their friend Hemant had 36 cows and 23 sheep.
Help Hemant keep track of his cows and sheep by making marks like Deba and Deep.
Teacher’s Note:
Encourage children to think of different strategies
to count large groups of objects without using numbers. They can
also use the above story as an activity where they can keep track of
all children entering and leaving the classroom.
Let us Do
Some animals and birds got together to play a game. They
wanted to make 2 teams. They decided that the captain of the
first team will be the one with the longest name, i.e., the one
with the most letters. The captain of the second team will be the
one with the shortest name, i.e., the one with the fewest letters.
Find out the captains of the 2 teams.
First team :
Letter count :
Second team :
Letter count
Do you know
any animal
having a longer
name than the
first team’s
captain?
2. Who has a longer name? Discuss.

Teacher’s Note:
Teacher can ask children to mark the shortest and
longest names among boys and girls and in the overall class. Help
them share their strategy through discussion in the classroom.
4. Teji and Jojo are making numbers using these cards.
Teji makes her roll
number 43 like this.
Its number name has

numbers that have the same number of letters in their number names.
