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

**I. Objectives**

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

a. multiply
decimals with five digits by two digits

b. place
the decimal point correctly in the product

c. Persevere
in one’s endeavor

**II. Subject Matter**

A. Multiplication
of Decimals (5 digits by 2 digits)

B.
BEC PELC I. 1.1; Mathematics for Everyday Life pp. 134-135

C.
flashcard, chart, chalkboard

D.
Perseverance

**III. Procedure**

**A. Preparatory Activities**

1.
Review

Give the product of the following:

1) 256 x 35 2) 8, 456 x 2 3)
12, 567 x 23 4) 3,
893 x 89

2.
Motivation

Ask: Which travels faster? Light or
sound? How can we observe which of the two is faster?

**B. Developmental Activities**

**1. Presentation**

Discuss that light travels faster
than sound. Encourage sharing of students’ ideas.

Ask: What are things you have
observed proving that light travels faster than sound?

If you see fireworks in the sky, what
will you observe first? The light or the sound coming

from the fireworks?

Introduce
the following problem:

Sound travles through air at a rate
of one meter per 0.00301 seconds. How long will sound travel through 3.5
meters?

Discuss the heuristics in multiplying
decimals.

Remind
students that the decimal point does not necessarily have to be aligned like in
adding or subtracting decimals.

Place
the decimal point on the product. Allow students to discover how was the decimal
point placed in the product.

**2. Exercise**

Multiply:

1)
0.3148 x 0.73

2)
1.2953 x 0.45

3)
56.78 x 0.21

4)
0.32341 x 1.3

5)
5.2332 x 25

**3. Generalization**

Ask: How do we multiply decimals?

How do we determine the correct
placement of the decimal point in the product?

**C. Application**

Present
the following scenario:

Liza can swim 0.124 foot in one second. How far
can she swim in 0.25 minute?

(Note: 60 seconds=1 minute)

Discuss
the problem to the class.

Ask:
Do you think Liza can still improve her swimming speed?

What must she do to improve?

Why do you think Liza reached that
achievement? Did she persevere?

**IV. Evaluation**

Give
the product.

1)
0.3149 x 0.43

2)
1.4543 x 3.7

3)
98.434 x .08

4)
0.78685 x 0.12

5)
5468.9 x 0.35

**V. Assignment**

Analyze
and solve:

Mrs. Mendoza’s farm is 0.349
kilometer long and 2.83 kilometer wide. What is the area of the farm?
