MOE MATHEMATICS CURRICULUM FRAMEWORK
Revised PSLE Format• Paper 2 allows pupils the use of calculators
to solve problems.
• Only calculators that are approved by SEAB will be allowed for use in the examinations.
( Casio fx - 95SG PLUS)
• The list of approved calculators is available on the
SEAB website - http://www.seab.gov.sg

Spiral Approach Math Curriculum
What is Problem - Solving?
Problem - Solving is the ability to handle unusual situations where routine procedures are not available.
(1) Routine questions :
Assess pupils’ knowledge,
basic computation skills and
familiar word problems
The figure below shows a rectangle. What is its perimeter ?
Example
7 cm
10 cm
Perimeter (10 + 7) cm x 2
= 34 cm
Ans: 34 cm
Assess pupils’ Thinking Skills and
require pupils to show competencies
that are beyond computational
proficiency
(2) Non- Routine questions :
Example
The figure below is made up of 3 squares of
different sizes. Line AB is a straight line, measuring
10 cm. Find the perimeter of the figure.
A B
= 10 cm
Perimeter of the figure 10 cm x 4
= 40 cm
4 - STEPS FOR PROBLEM-SOLVING: POLYA’S MODEL
Step1: Understanding the Problem.• What are the key words?• How would you describe the problem in your own words?
Step 2: Plan• Select the strategy to solve the problem. More than one strategy may be adopted.• Try common heuristics
(Model drawing, systematic listing, find a pattern, draw a diagram)
Step 3: Do• Use computational skills – add, subtract, multiply, divide• Use mathematical tools – ruler, metre ruler• Use thinking skills – classifying, comparing, sequencing, identifying pattern
Step 4: Check• Read your question again to make sure you have answered the question.• Check the working step by step.• Start with your answer and work backwards and check if the results satisfy
the given conditions.
Problem Solving Heuristicsare general methods or strategies of achieving a solution to a given
problem.
Thinking Skills• Classifying – using relevant attributes to sort, organise
and group information
• Comparing – using common attributes to identify commonalities
and discrepancies across numerous sets of information
• Sequencing – place items in a hierarchical order according to a quantifiable value
• Identifying patterns and relationship – recognise two or more attributes in a relationship that yields a reliable or repeated scheme
• Induction – drawing a general conclusion from clues gathered (from specific to general)
• Deduction – inferring various specific situations or examples from given generalizations
• Spatial Visualization – visualizing a situation or an object and mentally manipulating various alternatives for solving a problem related to situation or object without concrete manipulatives

Presentation of Answers
Alicia bought 8 plates and 5 cups. Each cup
cost $2.50 and each plate cost $4.90 more
than a cup. How much did she pay altogether?
(To use → instead of ‘=‘ to show a relationship )
5 cups $2.50 x 5
= $12.50
1 plate $4.90 + $2.50
= $7.40
8 plates $7.40 x 8
= $ 59.20
Total $59.20 + $12.50
= $71.70
Ans: $71.70

In a donation drive, 40 volunteers helped to distribute some
goodie bags. Each man distributed 4 bags while each woman
distributed 3 bags. The men distributed 34 more bags than the
women. How many men were there?

Pupils are expected to1. set own goals – know what they want to
achieve
2. complete and hand in work on time
3. present solutions in an organised way, showing important steps or workings and standard units
4. take note of their mistakes in their work and do corrections
5. go through their answers and check them carefully
6. seek help from teacher to clarify any doubts
Codes Representations
WM Wrong method to arrive at the same answer
CC Careless calculation (method is correct)
TE Transfer Error (within solution)
MR Misread (From question to solution)
MC Missing sentence tags/captions
MS Missing number sentences

Support from Parents
1. To ensure your child attend school regularlyand punctually
2. School work is to be done first3. Guide and not tell them how to do the work4. Time management – help to administer each revision
Paper 1 and Paper 25. To ensure no calculators is used in daily work unless
calculator logo is indicated6. Talk about Maths as used in day-to-day situation7. Should you have any concerns, do make an
appointment to see your child’s teacher to discuss8. If your child/ward has difficulty with her homework, do
not give her the answers but guide her with questions and indicate on the homework ‘assisted’ or ‘guided’.
