INTRODUCTIONOur nation’s vision can be achieved through a society later in life and in the process, benefit the society andthat is educated and competent in the application of the nation.mathematical knowledge. To achieve this vision,society must be inclined towards mathematics. Several factors have been taken into account whenTherefore, problem solving and communicational skills designing the curriculum and these are: mathematicalin mathematics have to be nurtured so that decisions concepts and skills, terminology and vocabulary used,can be made effectively. and the level of proficiency of English among teachers and pupils.Mathematics is integral in the development of science The Mathematics Curriculum at the primary leveland technology.

They prescribe theknowledge, skills or mathematical processes andvalues that should be inculcated and developed atthe appropriate levels. These behavioural objectivesare measurable in all aspects.In Points To Note, attention is drawn to the moresignificant aspects of mathematical concepts andskills. These aspects must be taken into accountsso as to ensure that the concepts and skills are taughtand learnt effectively as intended. xiv

These values should be imbibed throughoutAPPROACHES IN TEACHING AND LEARNING the process of teaching and learning mathematics.Various changes occur that influence the content and Among the approaches that can be given considerationpedagogy in the teaching of mathematics in primary are:schools.

The approaches that are suitable includethe following: • Cooperative learning; • Contextual learning; • Mastery learning; • Constructivism; • Enquiry-discovery; and • Futures Study.ASSESSMENTAssessment is an integral part of the teaching and learningprocess. It has to be well-structured and carried outcontinuously as part of the classroom activities. Byfocusing on a broad range of mathematical tasks, thestrengths and weaknesses of pupils can be assessed.Different methods of assessment can be conducted usingmultiple assessment techniques, including written andoral work as well as demonstration. These may be inthe form of interviews, open-ended questions,observations and assignments. Based on the results,the teachers can rectify the pupils’ misconceptions andweaknesses and at the same time improve their teachingskills. As such, teachers can take subsequent effectivemeasures in conducting remedial and enrichmentactivities to upgrade pupils’ performance. xx
