TEACHING METHODSAND TECHNIQUES


2/15

PRACTICAL WORK

A type of activity with its aim toobtain the final result directly fromthe work done.

Used to train pupils to use teachingaids to learn mathematical conceptsor facts.

Can also be used to master skill in

solving mathematics problem.


3/15

Examples of Mathematics Activities

Guide pupils to cut/fold papers into

several equal parts to learn the concept offraction

Guide pupils to divide a rectangle intoseveral equal squares to learn the conceptof area

Use measuring instruments to master theskill and concept of length, weight and

volume of liquid


4/15

Examples of Mathematics Activities

Use concrete objects such as marbles,

rubber seeds or abacus to master the skillof counting or certain operations.

Make geometrical models such as cuboid,cube and others to master thecharacteristics of solid geometry.


5/15

Advantages of Practical Work Method:

Would give confidence to the pupils Easier to understand and rememberconcepts/skills through their ownpractical experience

Through maths games, able toacquire their psychomotormanipulating skills.


6/15

EXPOSITORY METHOD

Expository can be referred as explicit and

comprehensive explanation of certainfacts.

A way of presentation of information to

pupils directly in the classroom.


7/15

Uses and Benefits:

To present information especiallywhen time is limited

To give directions To wrap up an activity


8/15

Problems and Concerns

Verbal learning tends to be passive

Organized according to teachersidea may not be the same withstudents, especially with culturallydiverse group of students.

What is said is not always what isheard.

Limited by the learners attention

span. Difficult for small children to follow

need concrete materials.


9/15

Laboratory Method:

May be defined as learning by doing

Often involves children playing andmanipulating concrete objects instructured situations.

Teacher plan systematic procedure,prepare sufficient equipments,organize group activities to ensurethe effectiveness of this method.


10/15

Examples of activities:

To study the characteristics of

geometrical block by measuring thelength of its sides

To study mathematics patterns,

relationships by using sets of objects To derive formula for the area of

rectangle

To understand relationships betweenunits of measurement by usingmeasuring devices.


11/15

DEMONSTRATION

Teacher shows the way or steps toperform a certain activity in the class.

There are two types of demonstrations: Traditional : teacher stands before the

group, shows something, and then tellswhat happened

Discovery : teacher silently conducts and

learners attempt to determine why what isshown occurs.


12/15

Tips to be applied:

Practice, practice and practicetry out first, to be sure you knowthat it will work out fine.

Take precautionsanticipatepotential accidents/problems.

Make everything visible elevate

demonstration materials as high as ispractical and safe.


13/15

Uses and Benefits

To protect learners when danger isinvolved

To show how to use something

To begin or end a unit of study To control time when the actionneeds to be stopped periodically toshow important changes or to pointout specific elements.


14/15

Uses and Benefits

To illustrate an important conceptwhen there is not enough equipmentand substitutions cannot be made

To develop problem solving skills

To grab learners attention beforeintroducing a concept or unit

To actively, mentally engage learnersin learning.


15/15

Problems and Concerns:

Demonstrations dont always work Learners may become restless and

inattentive Learners may have difficulty seeing

the demonstration The group may ask questions,

therefore the teacher must really

know precisely what happened andwhy.
