I. OBJECTIVES
Content Standards: The learner demonstrates understanding the order of operations, ratio and proportion, percent, exponent, and integers.
Performance Standards: The learner is able to apply knowledge of order of operations, ratio and proportion, percent, exponents, and integers in mathematical problems, and real-life situations.
Most Essential Learning
Competencies: The learner expresses one value as a fraction of another given their ratio and vice versa (M6NS-IIa-129)
Specific Objectives: a. Form ratio for groups of objects/numbers in colon, fraction and word form
b. Reduce ratio in lowest/simplest term
c. Maintain cleanliness of the school
II. SUBJECT MATTER
A. Understanding Ratio
B. K to 12 MELC, M6NS-IIa-129 p. 223
C. TV, pictures, slides presentation, models, graphic organizers
D. Cleanliness
III. PROCEDURE
A. ELICIT
Review on Fractions
· Post pictures of different garbage with fractions labeled on it.
· Let learners identify if the indicated fractions are in lowest/simplest terms or not.
· If the fraction is in lowest/simplest term, they need throw the garbage in the red trash bin.
· If the fraction is not in lowest/simplest term, they need to throw the garbage in green trash bin.
B. ENGAGE
Raise the following questions:
· What have you noticed with the garbage in the green trash bin?
In the red trash bin?
· Why do we need to throw our garbage properly? Integrate lessons in Science/TLE on waste management.
· What can you do to maintain cleanliness of our school?
C. EXPLORE
Group Task: Out of the Classroom Activity
· Divide the class in groups of 5-6 members.
· Each group will go out of the classroom and count the following around the school.
a) The number of classrooms in the Security Bank Building.
b) The number of classrooms in the JHS Building.
c) The number of flagpoles.
d) The number security guard.
e) The number of janitors/utility staff.
f) The number of Grade 6 teachers.
g) The number of coconut trees.
h) The number of sound horn.
i) The number of pillars in the gym.
j) The number of mushroom sheds.
· Each group will be given 10 minutes to finish the task. Have them strategize and collaborate to finish the task as quickly as possible.
· Remind groups to manage their noise as to not disturb other classes.
D. EXPLAIN
· Allow the groups to compare their answer. Present the table of the correct numbers/quantity to the class.
Units | Number |
a) classrooms in the Security Bank Building | 6 |
b) classrooms in the JHS Building | 20 |
c) flagpoles | 3 |
d) security guard | 1 |
e) Janitors/utility staff | 4 |
f) Grade 6 teachers | 7 |
g) coconut trees | |
h) sound horn | 2 |
i) pillars in the gym | 8 |
j) mushroom sheds | 2 |
· Discuss that quantities can be compared in the form of ratio. Provide the following examples using the following table:
· Relate that like fractions, ratios can be expressed in lowest/simplest terms.
Ratio | Colon Form | Fraction Form | Word Form |
The ratio of the security guard and Grade 6 teachers | 1:7 | 1/7 | one to seven |
The ratio of mushroom sheds to the pillars in the gym | 2:8 or 1:4 | 2/8 or 1/4 | one to four |
The ratio of classrooms in the Security Bank Building to the JHS Building | 6:20 or 3:10 | 6/20 or 3/10 | three to ten |
The ratio of sound horn to the mushroom sheds | 2:2 or 1:1 | 2/2 or 1/1 | one to one |
D. ELABORATE
Dyad Activity: Guide learners to practice forming ratios by completing the table below based on the following picture.
Ratio | Colon Form | Fraction Form | Word Form |
The ratio of banana peel to apple core | | | |
The ratio of tin can to plastic bag | | | |
The ratio of green bottle to soda can. | | | |
The ratio of spring to box | | | |
The ratio of paper to bottle cap | | | |
E. EVALUATE
Formative Assessment: Independent Task
· Direction: Answer the following ratio problems. Write your answer in colon, fraction and word form. Write in lowest/simplest terms if needed.
1. For every 2 cups of milk, 3 cups of cream are needed for fruit salad. Write the ratio.
2. There are 5 kites to seven boys.
3. There are 10 buses at a station. If each bus has 6 wheels, what is the ratio of buses to wheels?
4. Every quarter each student submits 2 projects in EPP. Give the ratio of projects to quarters.
5. There are 3 caimito trees and 4 mango trees in Mang Tino’s orchard. Write the ration of caimito trees to mango trees.
F. EXTEND
Assignment
· Direction: Create 2 problems/math scenarios that involve ratios. Write this in one half sheet (crosswise) pad paper.
