The document discusses representing large numbers using number discs. It provides an example of representing the number 42,045, which is the total number of barangays in the Philippines. It outlines the steps to do this: 1) Count the digits and determine the place value of each number. 2) Create a table separating the place values. 3) Use number discs to represent each place value based on the number in that place. In the example, it shows that 42,045 is represented by 4 discs of 10,000, 2 discs of 1,000, 4 discs of 100, and 5 discs of 1.

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

6. 2. Create a table separating the different place value
of the number

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