Name: Jane S. Ologuin

School: Nazareth Elementary School

District: Sergio Osmeña II District

I. Objective: Round decimals to the nearest tenths/ hundredths/thousandths

II. Subject Matter: Rounding decimals to the nearest tenths/hundredths/thousandths

Reference: Mathematics in Everyday Life p. 101-104

PELC II F 2.2

Materials: sheets of blank manila paper, flashcards

Value: speed and accuracy

III. Procedure:

A. Preparatory Activities

1. Drill on rounding off: mental computation

2. Motivation:

Agawan Panyo Game. (Involving decimals). Set the games and its rules to be followed.

B. Lesson Proper:

1. Presentation:

Luis climbed a 483 meter hill. If there are 1000 meters in 1 kilometer, what part of the hill did Luis climbed? Rounded to the nearest hundredths, what number is this?

2. Discussion:

1. What is asked in the problem?

2. What are the given facts?

3. What is process to be used?

4. What is the mathematical sentence?

5. What other thing is asked in the problem?

6. Why is the difference 517 rounded to 500?

7. What rule did you know?

3. Generalization:

Add 1 to the digit in the rounding place if the number to the right is 5 above. If it is less than 5, round down and drop all the digits after the rounding place.

4. Application

Round off the following number.

1.) 6.540

2.) 7.35

3.) .3982

4.) .055

5.) .64

IV. Evaluation:

Semi-Detailed Lesson Plan in Science 6

Name: Jane S. Ologuin

School: Nazareth Elementary School

District: Sergio Osmeña II District

I. Objective: Observe the stars as to color, size and brightness.

II. Subject Matter: Stars,: Their Size, Color and Brightness

Reference: TM Into the Future pp. 153-154

Science and Health VI, p. 247

Materials: a pair of binoculars

Value: appreciate the works of God

III. Procedure:

A. Preliminary Activities:

1. Checking of Assignment/review

What are the different instruments used by astronomers to gather information about stars?

B. Developmental Activities

1. Motivation:

You have sometimes watched stars at night. What are some of your observations?

2. Presentation

Observe the stars in a clear night sky. Do they appear to twinkle? What makes them twinkle?

What conclusion you can make about stars?

3. Discussion/Analysis

a. The sun is a star.

b. Stars produce their own light. Those that appear at night do not show the same brightness. Some blink continuously, others flicker weakly.

4. Concept Formation/ Generalization

What characteristics of the stars can be observed at night?

5. Application

In terms of weather condition, what does a starry night mean?

IV. Evaluation:

1. Besides yellow, identify other color of stars.(1-3)

2. Describe how stars may differ as to size.

3. Describe how stars differ as to brightness.

V. Assignment:

Observe a group of stars. Draw your observation in a bond paper.

1. In what ways stars differ?

2. Why do we see stars only during the night?

Name: Jane S. Ologuin

School: Nazareth Elementary School

District: Sergio Osmeña II District

I. Objective: Describe the relationship between the brightness as seen in thes distance of stars from the earth.

II. Subject Matter: Characteristics of Stars

Reference: TM Into the Future pp. 1556-158

Science and Health VI, p. 248

Materials: penlights, notebook

Value: attentiveness

III. Procedure:

A. Preliminary Activities:

1. Checking of Assignment/Review

How is the color of a star related to its temperature?

B. Developmental Activities

1. Motivation:

Why do some stars seem to look very faint?

2. Presentation

2.1. Activities: Pre-assign the activities, one or two days before class discussion)

3. Discussion/Analysis.

Distance affects the stars apparent magnitude. Other stars are very far away from the earth. Although their brightness is greater than that of the sun; we cannot see them during the daytime. The farther away the star is from the earth, the lesser is the apparent brightness that we see.

4. Concept Formation/ Generalization

How does distance affect the brightness of a star?

5. Application

Cite other explanations why stars appear in different brightness?

IV. Evaluation:

Explain in one or two sentences the relationship between distance and brightness of a star.

V. Assignment:

Explain: Why o we consider the sun as the brightest star?
