It has samples with good illustrations that help concretize and make better understanding of the lesson.

1. I want to see how
much money I
spend every day.

2. Hi there Ana.

your expenses.
How do I do that?
Simple. You could
use a circle graph.
Do you know what
it is and how to
make it?

you teach me?

3. Circle Graphs

4. Let’s analyze
Ana gets an allowance of Php140.00 a day. She
spends Php70.00 for lunch, Php35 for snacks,
Php17.50 for fare, and saves the rest. How much
does she save?

5. Let’s analyze…
Php70.00 Php35.00 Php17.50
We know that your money is 140
pesos. First, let is count how much is
spent from this amount and subtract
that to your money to get your savings

6. Php70.00 Php35.00 Php17.50+ +
=Daily cost: Php117.50

7. Daily cost: 117.50
money: 140.00
minus
savings: 17.50
equals

8. LUNCH, 70
SNACK, 35
FARE, 17.5
SAVINGS,
17.5
Using this Circle
graph we see
how you use
your money
everyday.
How do you
make a circle
graph?

9. How to make a Circle
Graph?

10. Steps in making a circle graph:
1. Get the percent of each item.
Php70.00
= 50%
÷
Php140.00

11. Steps in making a circle graph:
1. Get the percent of each item.
= 25%
Php35.00
÷
Php140.00

12. Steps in making a circle graph:
1. Get the percent of each item.
= 0.125%
÷
Php140.00
Php17.50

13. Steps in making a circle graph:
1. Get the percent of each item.
= 0.125%
÷
Php140.00
Php17.50

14. Steps in making a circle graph:
2. Determine the number of degrees for each
item. A circle contains 360°. To determine
the number of degrees for each item,
multiply 360° by the corresponding
fractional part or percent.

15. Php70.00 = 50%
360° x
50%
= 180°
0°

16. Php17.50 = 25%
360° x
25%
= 90°
0°

17. Php17.50 =0.125%
360° x
0.125%
= 45°
0°

18. Php17.50 =0.125%
360° x
0.125%
= 45°
0°

19. Steps in making a circle graph:
2. Using a compass, draw a circle. Mark the
center of the circle.

20. Steps in making a circle graph:
3. Using a protractor, draw in the circle the
number of degrees for each item.

21. Steps in making a circle graph:
3. Using a protractor, draw in the circle the
number of degrees for each item.

22. Steps in making a circle graph:
3. Using a protractor, draw in the circle the
number of degrees for each item.

24. LUNCH, 70
SNACK, 35
FARE, 17.5
SAVINGS,
17.5
This is now what
your circle graph
looks like.
Thank you, Ben.
