Unit I, Chapter 1, Lesson 3: Characteristics of Solids According to Shape

3

STRUCTURED LEARNING EPISODE

GRADE III

Competency:

Describe different objects based on their characteristics (e.g. Shape, Weight, Volume, Ease of flow)

(S3MT-Ia-b-1)

Classify objects and materials as solid, liquid, and gas based on some observable characteristics (S3MT-Ic-d-2)

Lesson:

Characteristics of Solids According to Shape

Objectives:

1. Name solids of different shapes

2. Group different solids based on their shapes

3. Describe the shapes of different solids

4. Enjoy in doing group activities

Reference:

K to 12 Learners Material pp. 4-5

K to 12 Teachers Guide pp. 4-6

Materials:

Empty boxes labeled with different shapes, real solids

Activities:

Priming

Song

Lead the class in singing the song I have to the tune of Where is Thumb Man, or a local song that the pupils can sing.

Where is Thumb Man

I have ballpens*

I have notebooks*

I have books*

I have chalk*

These objects are called solids (2x)

In our room (2x)

( *Give names of other objects found in the room)

Ask the pupils to get some objects from their bags. Each will stand and show the object while singing.

Activity

Activity Sheet 3: Shapely Solids

Analysis

(must be guided by the observations made from Activity 3)

1. Can you name the different solids?

2. What are these solids?

(Yes. Ball, plate, funnel, shoebox, others )

3. What different shapes of solids did you observe?

(triangle, oblong, star-shaped, sausage-like, others)

NOTE: Emphasize that the shape of the object may be related to things that they are familiar with, ex. Egg-like pebble )

A brief discussion on the different shapes may follow with illustrative examples.

4. What characteristic of solids is shown in the activity?

( Solids have shapes)

Abstraction

Do solids have shapes? What can you say about their shapes?

Solids have shapes, too. The molecules of solids are close together. They move back and forth but the particles do not change places. That is why solids do not change shapes.

Application

Have the class describe the characteristics of the following objects:

Closure

Are there solids of different shapes around us?

Can we group solids based on their shapes?

What are the shapes of solids?

(There are solids of different shapes around us, at home, in school, in the community. Solids are grouped if they have the same shape: round solids, oblong solids, rectangular solids. )

Assessment

Study the pictures of different objects. Choose the correct shape in the parentheses.

1. bag (rectangle, round, triangle)

2. ball (rectangle, round, triangle)

3. coin (rectangle, round, triangle)

4. pineapple (rectangle, round, triangle)

5. onion (rectangle, round, triangle)

Agreement

Each pupil will bring to class two (2) solids of the same kind, big and small, long and short, fat and thin which are not heavy to carry in their bags and a ruler.
