•1. What are the steps that we need to follow in reading
and writing number in words up to 10 000?”
In reading and writing numbers in words up to 10 000, we
simply need to follow the following steps:
1.Identify the place value of the digits of the given
number.
2.Write its expanded form by adding the value of each
digit.
3.Write the number I words equivalent to the values in
expanded form.
4.Write the final answer.

4. 2. “How about the steps in reading and writing
number in symbols up to 10 000?”
In reading and writing numbers in symbols, we should
take the reverse process of the above steps or simply
follow the steps.
1.Determine the place value in the number in words.
2.Write the expanded form.
It is based on the values found in the number in
words.
3. Identify the first digit (from the left) in each value.
Then write the final answer.
Very good let’s give ourselves a power clap.

5. DRILL
MOTIVATION
DISCUSSION (ACTIVITY)
PLEASE COUNT OFF 1-3
Group yourselves according to your number. And each will be
given a task. Based on the given number in the problem
Group 1, your task is to find the place value of each digit in
the given number. For group 2, your task is to find the value
of each digit in the given number, and for group 3, your task
is to write the number in words.
• You have 10 mins to work on your task and afterwards a
representative of each group will present your work. Do you
understand the activity?
Okay, you may now start

6. Let’s begin with the group 1.”
(Group 1 will present their activity)
“Job well done Group 1. You’ve got the correct answer.”
“Let’s proceed to Group 2.
(Group 2 will present their work)
“Job well done Group 2. You’ve got also the correct answer.”
“Clap your hand for them”
Let’s proceed to the last group”
(Group 3 will present their work)
“Job well done Group 3. You’ve got the correct answer.”
I am so glad that all of the group got the correct answers. It seems like
you are ready for our discussion this morning.
You all deserve a big around of applause.

7. Abstraction
So, our topic for today is about numbers and number
sense wherein we are going to give the place value and
value of a digit in numbers up to 100 000 and read and
write numbers up to hundred thousand in symbols and in
words.
Let us see if we have the same answer. Read and follow
the presentation. Then, let us check if you were able to
read and write the numbers in symbols and in words
correctly. Let us also find out if you were able to give the
correct place value and value of each digit.

8. Reading numbers up to
hundred thousands

9. WRITING NUMBERS IN SYSMBOLS
Now were going to write 48 052 . For the first step
lets prepare a place value chart namely the thousands
period and the hundred period. In the units periods
we have the ones place, the tens place and the
hundreds place. And under the thousand period we
have the thousand period, the ten thousands period
and the hundred thousands period. Now were going
to write the numeral under each period. In the given
number forty eight thousand fifty two what number
is in the thousands period? Correct! 48 so we will
write the number 48 under the thousands period.
Next what number is in the units period? Correct! 52
we will write the numeral 52 in the units period.

10. Now we will place the each digit in its correct place value.
The number 52 under units period means ones and tens.
we will place 2 in the ones place and the digit 5 in the
tens place. And number 48 under the thousands period
means four thousands and eight ten thousands. We will
place 8 in the thousands place and the digit 4 in the ten
thousands place. But if you’re going to take a closer at our
place value chart here we can see that there is not digit in
the hundred place and simply means that there are no
hundreds, but we will not the hundred place empty. Since
it means no hundreds so we will write the digit zero to
complete the digits in the units period. Our value chart
here shows 4 ten thousands, 8 thousands , 0 hundreds, 5
tens and 2 ones and this is equal to ( forty eight thousand,
fifty two.

11. Writing numbers in words
We’re going to place first each digit of the number in
the place value chart. In reading and writing
numbers and in symbols remember the period is
very important and since we’re reading and writing
numbers up to 100 000 so we have to remember two
periods namely the units periods and thousands
period. Under the units period we have the ones
place the tens place and the hundred place. And
under the thousands period we have the thousands
place the ten thousands place and the hundred
thousands place.

12. 75 326
Now we’re going place each value digit of the
number in the place value chart.
So we will place the digit 6 in the ones place
2 in the tens place
3 in the hundred place
5 in the thousand place
And 7 in the ten thousand place
Now we’re going to read the number by period,
lets start reading from left to right. So lets start
reading in the thousand period going to the unit
period.

13. Looking at the number found in our place value chart. How do
we write the numerals in the ten thousand place? Correct 68!
So we will write the word sixty eight here. Now were going to
write the name of the period, write the singular name of the
period instead of saying in thousands we say thousand. We will
write the word thousand here so, the number in the thousands
period is (sixty eight thousand) now were going to read the
number in the thousand period. We don’t mention the name
of the period when it is in units. And how do we read the
numeral in the units period? Correct! Its three hundred twenty
six. So we will only write three hundred twenty six here not
mention the name of the period when it is in unit. Now to
separate the period we will use comma. We put the comma
after the word thousand. So the number word for 75 326 is
sixty eight thousand three hundred twenty six

14. Now, you already learned the place
value and value of a digit in numbers
up to 100 000 and how to read
numbers up to hundred thousand.
This time you are now ready for the
activities. LET’S GO!
