JENIS MODEL PENGAJARAN : Model Pemprosesan Maklumat.

Inkuiri : Model ini,murid melibatkan diri dalam menguji konsep dan hipotesis.

Murid akan mengambil bahagian yang aktif dalam pembelajaran, menganalisis

data,menyemak hipotesis dan membuat refleksi terhadap pembentukan ilmu yang

timbul.

Ekspositori : Model ini murid akan akan menerima isi pelajaran dari guru. Murid tidak

digalakkan memikirkan atau menyoal tentang apa yang dipelajari.Mereka hanya

mempelajari apa yang patut dipelajari sahaja.

Class : 3 Naim

Time : 10.10am – 11.10am (60 minutes)

Objective :

At the end of this lesson, pupils should be able to identify different nets that can be

used to form a model of cube at least 6 from 8 questions in the worksheet

given

Prerequisite knowledge:

Pupils are able to identify the name of 2-D shapes and 3-D shapes

Strategy : Using a model, inquiry activity

Set induction (5 minutes): Colgate box is shown to pupils. Teacher asks pupils how the box is built. Teachers cut the box and show the nets of the box

STEP CONTENT LEARNING ACTIVITIES REMARKS

1(10 minutes)

Find different nets of cube

i. Pupils are divided into 6

groups.

ii. Each group will be given

three models of cubes

iii. Pupils need to identify

the characteristics of

cube

iv. Next, they are required to

cut their desired lines of

the box to open the cube

in different ways as

possible

v. Ask pupils to count how

many edges need to be

cut to open a cube

Step 2(10 minutes)

Comparing and discussing

i. Pupils show the nets that

they obtain

ii. Ask pupils what are the

similarities between all

nets

iii. Help students to

discover the common

properties of:

- Each net has six

faces.

- Six faces are

connected with five

edges.

- Seven edges should

be cut to open a cube

and to make a net

Example of nets

Step 3(10 minutes)

Select the real nets of cubes

i. In groups, pupils are

given a worksheet

showing many

different nets for

making a cube but not

all can form a

cube(refer to

worksheet 1)

ii. They are required to

study the nets given

and circle those that

they think can form a

cube

iii. Teacher encourage

pupils to check the

answer by cutting out

the nets and try to

form cubes from

these

Teacher emphasizes that there

are some nets which have six

squares but cannot be folded to

form a cube

For example :

This net with six faces arranged

3 by 2 when attached together

cannot be folded to form a cube

Step 4(10 minutes)

Construct another nets

In groups, pupils need to draw

the other possible nets that can

form a cube.

Evaluation (10 minutes)

Worksheet(identify

features and nets of cube

shapes)

i)Pupils describe the

characteristics of a cube

ii)Pupils identify different nets of

cubes

Closure (5 minutes)

Teacher emphasizes the whole

topics

-There are ’35 different’ ways of

joining 6 squares together, edge

to edge and of these only 11

may be made up into cubes.

-Each net of cube has six faces.

Six faces are connected by five

edges. Seven edges should be

cut to open a cube and to make

a net.

- Five edges must remain

attached in order to make a

cube turn into a two-

dimensional pattern from a

cube.

Worksheet 1

There are several nets of cubes above. But not all the nets given can form cubes with no faces

overlapping. Circle those that you think can be used for a cube. Be careful!
