Grade 4 Mathematics

1. Lesson 1: Visualizing Numbers
Up to 100 000

2. In the Philippines, there are a total of 42
045 barangays in all.
How big is the number 42 045?

3. STEPS IN REPRESENTING NUMBERS USING NUMBER
DISCS
 COUNT THE NUMBER OF DIGITS AND DETERMINE THE PLACE VALUE OF
EACH NUMBER
 CREATE A TABLE SEPERATING THE DIFFERENT PLACE VALUE OF THE
NUMBER
 USE NUMBER DISCS TO REPRESENT EACH PLACE VALUE

4. NOW LET’S USE NUMBER DISCS IN THIS
SITUATION

5. 1. count the number of digits and determine the place
value of each number
4 2 4 0 5
1 2 3 4 5 number of digits
Ones
Tens
Hundreds
Thousands
TenThousands

6. 2. Create a table separating the different place value
of the number
5 4 3 2 1

7. 3. Use number discs to represent each place value.

Zero 10s

8. REMEMBER
The number in each place value will determine the
number of DISCS you will use.
