  1. Use of Calculators in Primary Mathematics 29 February 2008

  2. Use of Calculators in Primary Mathematics RATIONALE • The introduction of calculators at P5 and P6 aims to : • Achieve a better balance between emphasis on computational skills and problem solving skills in teaching and learning and in assessment; • Widen the repertoire of teaching and learning approaches to facilitate the use of investigations and problems in authentic situations; and • Help students, particularly those with difficulty learning mathematics, develop greater confidence in doing mathematics.

  3. To investigation the approximate value of π Use of Calculators in Primary Mathematics CALCULATOR ACTIVITY - Example • 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. • Divide the circumference of the circle (C) by its diameter (D). • Compare your answer with their friends’. Do you notice that this value is about the same for any circle? Let’s call it π.

  4. To solve real-life problem – Budget Tour Use of Calculators in Primary Mathematics CALCULATOR ACTIVITY - Example Your family is planning for a holiday. Look at the different packages offered in the newspaper and work out a budget for your family.

  5. Use of Calculators in Primary Mathematics IMPLEMENTATION SCHEDULE PSLE

  6. Use of Calculators in Primary Mathematics 2007 SYLLABUS • 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. • 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.

  7. + Conceptual understanding is still important Example: 3 + 1 • Teach the concept using manipulatives • Enhance the concept using pictorial representation • Add the mixed numbers using calculators 3 + 1 = 3 + 1 = 4

  8. Use of Calculators in Primary Mathematics PREPARATION FOR THE IMPLEMENTATION • By MOE • Workshops on the use of calculators in primary mathematics have been conducted to equip teachers with the knowledge and skills to integrate and make effective use of calculators in the teaching and learning of mathematics. • Resource materials such as textbooks and teaching and learning guide have been updated in time for the implementation of the revised syllabus. By SCHOOL • An introductory workshop to P5 pupils on Jan 10. • A briefing for P5 parents on Feb 29.

  9. Use of Calculators in Primary Mathematics 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.

  10. Use of Calculators in Primary Mathematics CHANGES IN PSLE FORMAT • As calculators will be allowed in one part of the examination, there is a need to restructure the examination format into two papers: – Paper 1 is the non-calculator component to ensure that important computational skills continue to receive emphasis (MCQ and short answer questions) Paper 2 is the component which allows the use of calculators. (Short answer & structured/long answer questions) • The two papers will be taken on the same day with an administrative break between the papers.

  11. Use of Calculators in Primary Mathematics CHANGES IN PSLE FORMAT • There is no change in the item types and in the weighting and number of questions for each type from the current format. • 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.

  12. Use of Calculators in Primary Mathematics TYPES OF CALCULATORS • Only calculators that are approved by the Singapore Examinations & Assessment Board (SEAB) will be allowed in the examination. • The list of calculators is available on SEAB’s website: http://www.seab.gov.sg • To maintain continuity from primary to secondary education, these calculators can also be used at the secondary level.

  13. Use of Calculators in Primary Mathematics Tips for Parents • Basic manual computation • Mental calculation • Exposure to real-life application of Maths • Writing of mathematical statements (methods) • Calculator is allowed when there is an icon next • to the problem in the textbooks and workbooks.

  14. Use of Calculators in Primary Mathematics Where to get INFORMATION • You can get information on the revised maths syllabus 2007 @ http://www.moe.gov.sg/cpdd/pri_maths_links.htm • The list of approved calculators @ http://www.seab.gov.sg/SEAB/psle/CalCir2008.pdf • Frequently Asked Questions on the use of calculators and this set of slides at our school’s webpage @ http://www.chijpritoapayoh.moe.edu.sg under mathematics department
