**Lesson Plan in Math 6 (Integrated with Science)**

**I. Objectives**

At
the end of the class, the pupils are expected to:

a.
compare dissimilar fractions using different methods

b.
identify which fraction is greater or less than the other or if the fractions
are equal

c. take
care of planet Earth

**II. Subject Matter**

A.
Comparing Fractions

B.
BEC PELC g.10; Mathematics for Everyday Use 6 pp. 68-70

C.
chart, paper strips, chalkboard

D.
Care for planet Earth

**III. Procedure**

**A. Preparatory Activities**

1.
Motivation

Ask: What are the eight planets of the solar
system?

What planet is the largest? The
smallest?

**B. Developmental Activities**

**1. Presentation**

Present
the following problem:

Venus is approximately 9/10 the size
of the Earth while Mars is 7/13 the size of the Earth.

Which planet is bigger?

Discuss
among the pupils their guesses. Let them rationalize their answer.

Provide
various methods to test their answers:

Method
1: Paper Strips

Method
2: Cross Multiplication

Method
3: Rewriting fractions to similar fractions

Let
pupils choose their preferred method to compare fractions.

Relate
values infusion to the lesson. Discuss that Venus is once believed to be
habitable planet but due to extremely great amount of greenhouses gases present
in the planet, it became the hottest planet in the solar system.

Ask: What do you think will happen
to Earth if greenhouse gases will continue to increase in our atmosphere? How
can we minimize greenhouse gases in our atmosphere?

**2. Exercise**

Compare
the fractions. Encircle the larger fraction.

1)
3/5,7/8

2)
9/17, 5/15

3)
8/10, 4/11

4)
2/5, 6/7

5)
9/13, 2/5

6)
3/4, 5/7

7)
8/7, 6/5

8)
1/3, 2/4

9)
3/7, 4/11

10)
8/12, 2/6

**3. Generalization**

How do we compare dissimilar
fractions? What are the different methods in comparing fractions?

**C. Application**

Consider
the following problem:

Barangay Kalikasan planted 3/5 of
the forestland with tree seedlings while Barangay Kalinisan planted 6/10 of the
area. Which barangay planted the wider area?

**IV. Evaluation**

Compare
the following pair of fractions by writing <,> or =.

1)
6/3 ___ 3/7

2)
5/8 ___ 5/14

3)
4/9 ___ 7/6

4)
2/10 ___ 9/12

5)
1/2 ___ 2/4

6)
3/4 ___ 4/8

7)
4/6 ___ 6/5

8)
5/8 ___ 8/10

9)
6/9 ___ 7/8

10)
7/13 ___ 11/16

**V. Assignment**

Box the smaller fraction. Try to
look for pattern.

1)
2/5, 2/8

2)
4/12, 3/12

3)
4/9, 4/6

4)
8/13, 12/13

5)
