Set
Induction
(5 minutes)
|
Comparison
between surfaces of coins.
|
-
Pupils show a 10-sen coin and a 50-sen 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.

Introduction
of the concept area.
Calculation
the area using arbitrary unit.
Introduction
of the standard unit of area as cm2
|
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:
Teacher
shows a triangle that consist a length of 5cm and width of 3cm. teacher then
show the formulae on how to find the area of a rectangle
AREA: Length x Width
5cm x 3cm = 25cm²
Teachers
then show another questions and let the students to find the answers.
Find the area of this square?
4cm x 4cm =16cm²

REFLECTION:
STRENGTH:
- Pupils know how to use the formula(area=length x width) wisely.
- Pupils able to finish all the questions in 5 minutes.
- Pupils understand the concept of area by using teaching aids that provided by teacher.
WEAKNESSES:
- Pupils confuse in finding the area of a square.
- Remedial students still can understand the concept of area.
- Not enough time for teachers in discussing the answers with pupils.
STEPS TO OVERCOME THE PROBLEM:
- Teacher will using power point in delivering his teaching activities. By using this method, pupils will enjoy the learning activities.
- Teacher will manage time evenly so that there will be enough time in discussing the answers.
- Teacher will explain the formula of finding the area more clear to the students.
