Shape Lesson plan
DAILY LESSON PLAN
Subject  : Mathematics 
Classs  : 5 Cekal 
Enrolment  : 36 pupils 
Duration  : 1 hour 
Topic  : Shape and Space 
Learning Area  : Area of Composite 2D Shapes 
Learning Objectives  : Pupils will be taught to measure and calculate the area of 2D shapes. 
Learning Outcomes  : Pupils will be able to

Previous knowledge  : Pupils had learnt how to measure perimeter of composite 2D shapes. 
Thinking Skills  : 
Inculcation of values  : Be grateful & appreciate the value of coins. 
Teaching Aids  : Coins, white flip paper, pieces of manila card,marker, measuring tape, textbook , Power Point presentation, LCD projector. 
Step / Duration  Content  Teaching and Learning Activities  Remarks  
Set Induction (5 minutes)  Comparison between surfaces of coins.   Pupils show a 10sen coin and a 50sen coin. Pupils point out the whole part of the respective faces of the coins. Pupils are guided to make comparison between both surfaces of the coins and find out which coin has a bigger surface and which coin has a smaller surface. Repeat the activity above by comparing surface of tables,books, pencil boxes and other things in the class.  KBKK: Comparing & contrasting MI: Bodily/inaesthetic Teaching aid: coins. Moral value: Be grateful & appreciate the value of coins.  
Step 1 (5 minutes)  Introduction of the concept area. Calculation the area using arbitrary unit.  Based on the activity of set induction above, pupils are introduced to the concept of area by substituting the word ‘face (or surface)’ to ‘area’ so that the pupils can express that: “Area is the size of the region or surface of a closed plane figure’. A geometrical board is displayed. Pupils find the area by counting the number of squares included in the area shown:
Pupils are guided to express that : Area A is 3 square units Area B is 5 square units. Area C is 6 square units. The following square cards are displayed one by one. Pupils find the area of each figure:  MI: Visualspatial Logical/ Mathematical Teaching aid: Geometrical board  
Step 2: (10 minutes)  Introduction of the standard unit of area as cm^{2}  A square card of 1 cm x 1cm introduce cm^{2}as one of the standard unit for are :
Area of a shaded square = 1cm x 1cm = 1 cm^{2} 1 cm^{2 }read as one square centimetre. The square cards of composite 2D shapes (refer to the attachment) are shown Pupils are guided to express: “Area A has 9 cm^{2 “} “Area B has 4 cm^{2 “} Total area is 13 cm^{2}  MI: Visualspatial Logical/ Mathematical Teaching aid: Geometrical board  
Step 3 (15 minutes)  Introduction the area formula for composite 2D shape.  A square card of 3cmx 5cm is displayed. Pupils find the area of the card by counting the number of squares in it. Pupils are then guided to find the measurement of length and breadth of the rectangle, and use the discovery method to obtain the area formula of a rectangle: Are of rectangle = 5cmx3cm= 15cm^{2.} ^{}Theabove steps repeated with square card of 2cm x 2cm until pupils obtain the area formula of a square. Both of the rectangle and square are combined to form a composite 2D shape.  Pupils add the area of rectangle and square to obtain the total area of the composite 2D shape.  Teaching strategy : Discovery method  
Step 4 ( 20 minutes)  Group calculation of 2D area.  Teacher divides pupils into a group of 6. Each group will be given a different set of composite 2D shapes with the measurement. Pupils calculate the area of the composite shapes. Pupils present their answer and teacher checks their answer.  KBKK: Solving problems  
Closure (5minutes)  Summary of the lesson  Pupils summarize the lesson by explaining the area formula for rectangle and square. Teacher distributes the worksheet as a homework.  KBKK: Making summaries Worksheet
