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.
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.

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
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
CALCULATOR ACTIVITY - Example Use of Calculators in Primary Mathematics
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 .
To investigation the approximate value of π
