1) The document provides lesson plans and activities for teaching students about visualizing percent and its relationship to fractions, ratios, and decimals using models. 2) Activities include using cardboard strips to represent fractions, a relay game, and a survival game to demonstrate ratios. Students will also complete worksheets to practice converting between ratios, fractions, decimals, and percentages. 3) A final evaluation assesses students' understanding of converting between ratio, fraction, decimal, and percentage forms and applying these concepts to word problems.

What is the meaning of per cent?

4. Review
Materials: cardboard strips representing 10’s and 1’s
Mechanics:
a. Divide pupils into 4 groups.
b. Cardboard strips representing 10’s and 1’s will be
distributed to the four groups.
c. Teacher will gives a problem and the pupil from each group
hurriedly answers the questions using the cardboard strips
Pupils having the strips with 10 division and one division each
to represent as the answer will reach in front showing the
answer.
Relay Game:

5. Motivation:
Through a song about percent.
What is the song all about?

6. Presentation:
Survival Game
Mechanics:
1.Let 5 boys and 5 girls stand in front of the class forming a
circle. While the music is being played the participants move
around.
2. When the music stops the teacher will say “The boat is
sinking group yourselves into 2.”
3. The group continues till the described players necessary to
form the ratio is achieved.

7. For instance, the first group there are 3 girls and 1 boy left.
Then the ratio of boys to girls is 1:3
The ratio of girls to boys is 3:1
If we are to write the ratio 1:3 in fraction which will be the
numerator? the denominator?
If we are to get how many percent of the pupils are boys, in
relation to the group, divide the numerator by denominator.
Discussion:
33 1.00
.33or 33%

8. Discussion:
There are 33% in relation to the girls in the group.
In decimal, change percent to fraction with
denominator of 100. Then express the fraction
as a decimal.
33= 0.33
100
Or simply drop the % symbol, Then move the decimal point 2
places to the left.
33% = .33 = 0.33

9. A. Using pictures the pupils will give the ratio of the
number shaded parts to the unshaded part. Then change
them to fractions, decimal and percent.
Performing the Activities
Ratio _______ Fraction ______ Decimal _______ Percent ________

10. B. Group Activities
Have the pupils work in group. Each group will be
given enveloped containing the activity that they need
to work together to come up for the correct answer.
Each group will discussed in front of the class on how
they come up with their answer.
Performing the Activities

11. Directions: Write the ratio, decimal and percent equivalent of
each picture.
Reinforcing the Concept and Skill

12. What is the relationship of ratios to fractions?
To percent?
If your data is written in ratio form, can you write it
in fraction form?
How can we get percent equivalent of a ratio and a
fraction?
Generalization:
Percent is a ratio of a number 100. Ratio is a
comparison between two or more quantities. It can also
be expressed as fraction, the first number being the
denominator. Through ratios and fractions we can get the
percent equivalent by dividing the numerator by the
denominator. The result is a decimal but can just move
the decimal point two places to the right and affix the
percent sign.

13. Learners will be given cut outs of different grid and they will count and
write the name for each shaded part as a fraction, as a decimal, as a
percent and as a ratio. Write your answer on each cut outs given to you.
