1. 1. 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, menganalisisdata,menyemak hipotesis dan membuat refleksi terhadap pembentukan ilmu yangtimbul.Ekspositori : Model ini murid akan akan menerima isi pelajaran dari guru. Murid tidakdigalakkan memikirkan atau menyoal tentang apa yang dipelajari.Mereka hanyamempelajari apa yang patut dipelajari sahaja.
2. 2. Class : 3 NaimTime : 10.10am – 11.10am (60 minutes)Objective :At the end of this lesson, pupils should be able to identify different nets that can be usedto form a model of cube at least 6 from 8 questions in the worksheet givenPrerequisite knowledge:Pupils are able to identify the name of 2-D shapes and 3-D shapesStrategy : Using a model, inquiry activitySet induction (5 minutes): Colgate box is shown to pupils. Teacher asks pupils how thebox is built. Teachers cut the box and show the nets of the box STEP CONTENT LEARNING ACTIVITIES REMARKS 1 Find different i. Pupils are divided into 6(10 minutes) nets of cube 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 Comparing and i. Pupils show the nets that
3. 3. (10 minutes) discussing 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 Select the real i. In groups, pupils are(10 minutes) nets of cubes given a worksheet showing many different nets for making a cube but not all can form a cube(refer to
4. 4. 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 Construct In groups, pupils need to draw(10 minutes) another nets the other possible nets that can form a cube. Evaluation Worksheet i)Pupils describe the(10 minutes) (identify characteristics of a cube features and ii)Pupils identify different nets of nets of cube
5. 5. shapes) cubes Closure Teacher emphasizes the whole (5 minutes) 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 1There are several nets of cubes above. But not all the nets given can form cubes with no facesoverlapping. Circle those that you think can be used for a cube. Be careful!
