• In the implementation of the 2007 revised mathematics syllabus, one of the significant change is the introduction of calculators at the primary mathematics at P5 in 2008 and at P6 in 2009. Let me share with you on the rationale for its introduction, some research findings, the impact on teaching and learning, the change in the PSLE examination format, the types of calculators for use as well as financial schemes available.
• ### Calculator Information Kit - Bukit Panjang Primary Mathematics Curriculum

1. 1. Use of Calculators in Primary Mathematics
2. 2. <ul><li>The introduction of calculators at P5 and P6 aims to : </li></ul><ul><li>Achieve a better balance between emphasis on computational skills and problem solving skills in teaching and learning and in assessment ; </li></ul><ul><li>Widen the repertoire of teaching and learning approaches to facilitate the use of investigations </li></ul><ul><li>and problems in authentic situations; and </li></ul><ul><li>Help students, particularly those with difficulty learning mathematics, develop greater confidence in doing mathematics. </li></ul>RATIONALE Use of Calculators in Primary Mathematics
3. 3. CALCULATOR ACTIVITY - Example Use of Calculators in Primary Mathematics Your family is planning for a holiday. Look at the different packages offered in the newspaper and work out a budget for your family. To solve real-life problem – Budget Tour
4. 4. CALCULATOR ACTIVITY - Example Use of Calculators in Primary Mathematics Your calculator has a broken key. How do you show 55 on your calculator without using the broken key? Find as many ways as you can of showing the number 55 on your calculator. 5 To explore – Broken key on calculator
5. 5. CALCULATOR ACTIVITY - Example Use of Calculators in Primary Mathematics <ul><li>Draw a circle (or use real objects such as a CD or a plate) and measure its diameter (D) and its circumference (C) using a piece of string. </li></ul><ul><li>Divide the circumference of the circle (C) by its diameter (D). </li></ul><ul><li>Compare your answer with their friends’. Do you notice that this value is about the same for any circle? Let’s call it π . </li></ul>To investigation the approximate value of π
6. 6. IMPLEMENTATION SCHEDULE Use of Calculators in Primary Mathematics P6 Mathematics P6 Foundation mathematics 2009 P5 Mathematics P5 Foundation Mathematics 2008 Level of implementation Year of implementation
7. 7. <ul><ul><li>The use of calculators created a computational advantage and more often resulted in the selection of a proper approach to a solution in </li></ul></ul><ul><ul><li>problem solving. </li></ul></ul><ul><ul><li>Students in elementary schools who used </li></ul></ul><ul><ul><li>calculators possessed better attitudes and had </li></ul></ul><ul><ul><li>better self-concepts in mathematics . </li></ul></ul><ul><ul><li>There were significant differences in problem solving , computation , and conceptual understanding , favouring students who used calculators to those who did not. </li></ul></ul>RESEARCH FINDINGS Use of Calculators in Primary Mathematics
8. 8. 2007 SYLLABUS <ul><li>The four operations will continue to receive emphasis at all levels. This will ensure that students develop basic numeracy skills and acquire a strong foundation in arithmetic. </li></ul><ul><li>Estimation and mental calculation skills will continue to be part of the syllabus, as these skills are required to check the reasonableness of answers obtained from calculators. </li></ul>Use of Calculators in Primary Mathematics
9. 9. PREPARATION FOR THE IMPLEMENTATION <ul><li>Workshops on the use of calculators in primary </li></ul><ul><li>mathematics have been conducted to equip </li></ul><ul><li>teachers with the knowledge and skills to integrate </li></ul><ul><li>and make effective use of calculators in the </li></ul><ul><li>teaching and learning of mathematics. </li></ul><ul><li>Resource materials such as textbooks and teaching and learning guide have been updated in time for the implementation of the revised syllabus . </li></ul>Use of Calculators in Primary Mathematics
10. 10. CALCULATORS IN PSLE To align the assessment with the curriculum, calculators will be allowed in one part of the Primary School Leaving Examination (PSLE) Mathematics and Foundation Mathematics examinations from 2009 . Use of Calculators in Primary Mathematics
11. 11. CHANGES IN PSLE FORMAT <ul><li>As calculators will be allowed in one part of the examination, there is a need to restructure the examination format into two papers: – </li></ul><ul><li>Paper 1 is the non-calculator component to ensure that important computational skills continue to receive emphasis </li></ul><ul><li>Paper 2 is the component which allows the use of calculators. </li></ul><ul><li>The two papers will be taken on the same day with an administrative break between the papers. </li></ul>Use of Calculators in Primary Mathematics
12. 12. CHANGES IN PSLE FORMAT <ul><li>There is no change in the item types and in the weighting and number of questions for each type from the current format. </li></ul><ul><li>The demand and difficulty level of the papers in the new format will be maintained and kept comparable with those of the previous years’ papers . </li></ul>Use of Calculators in Primary Mathematics
13. 13. TYPES OF CALCULATORS <ul><li>Only calculators that are approved by the Singapore Examinations & Assessment Board (SEAB) will be allowed in the examination. </li></ul><ul><li>The list of calculators is available on SEAB’s website: http://www.seab.gov.sg </li></ul><ul><li>To maintain continuity from primary to secondary education, these calculators can also be used at the secondary level. </li></ul>Use of Calculators in Primary Mathematics
