    Primary 5 Mathematics Curriculum Briefing

    for Parents 22 January 2014

  • Vision

    A community of confident and motivated pupils who are both effective problem solvers and team players.

  • Mission

    To equip pupils with the necessary mathematical knowledge and skills for everyday life and for continuous learning in mathematics and related disciplines.

  • Change in Emphasis in the Maths Curriculum

    Older Curriculum :

    Focused on computations and routine


    Revised Curriculum :

    Focuses on Problem - Solving.

    Pupils are not expected to do tedious


  • 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 ?


    7 cm

    10 cm

    Perimeter (10 + 7) cm x 2

    = 34 cm

  • Assess pupils Thinking Skills and

    require pupils to show competencies

    that are beyond computational


    (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

  • PSLE Format Paper 1 does not allow the use of a


    This is to ensure that important computational skills will continue to be emphasized and be assessed.

  • 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 -

  • 4 STEPS FOR PROBLEM-SOLVING: POLYAS MODEL Step1: Understanding the Problem. What are the key words? What are the conditions to be met? How would you describe the problem in your own words?

    Step 2: Devising a Plan Select the strategy to solve the problem. More than one strategy may be adopted. Try common heuristics (Model drawing, make a list, make a table, draw a diagram, find a pattern, guess and check, work

    backwards, logical thinking)

    Step 3: Carrying out the Plan. Use computational skills add, subtract, multiply, divide Use mathematical tools ruler, compass, protractor Apply formula eg. Distance = Speed x Time Use thinking skills

    Step 4: Reflecting 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


  • Problem Solving Heuristics are general methods or strategies of achieving a solution to a given problem.

    6 Find a Pattern

    7 Draw a Diagram

    8 Restate The Problem

    9 Guess and Check

    10 Working Backwards

    11 Make an Assumption

  • Pupils are expected to 1. 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 and 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

  • Support from Parents 1. To ensure your child attend school regularly and punctually 2. School work is to be done first. 3. Guide and not tell them how to do the work 4. Time management help to administer each revision Paper 1 and Paper 2 5. To ensure no calculators is used in daily work unless calculator logo is indicated 6. Talk about Maths as used in day-to-day situation 7. Should you have any concerns, do make an appointment to see your childs teacher to discuss

  • Examples of Word Problems Involving the use of Heuristics

  • Sam paid $1170 for a dining table, a bookshelf and a set of sofa. The dining table cost $120 more than the sofa. The sofa cost 3 times as much as the bookshelf. How much did the dining table cost?

    Dining Table

    $120 Sofa



    7 units $1170 - $120 = $1050 1 unit $1050 7 = $150 Dining Table $(3 x 150) + $120 = $570

    Check!!! Dining table $570 Sofa $570 - $120 = $450 Bookshelf $450 3 = $150 Total $570 + $450 + $150 = $1170

  • Sarah has some 50 and $1 coins that add up to $28.50. She has 3 more $1 coins than 50 cent coins. How many 50 coins does Sarah have? Value of the excess $1 coins 3 $1 = $3 Value of equal number of coins $28.50 - $3 = $25.50 1 set one 50 coin and one $1 coin Value of 1 set $0.50 + $1 = $1.50 Number of sets $25.50 $1.50 = 17 Sarah has 17 50 coins.

    Check!!! Value of 50 coins 17 x 50 = $8.50 Value of $1 coins $17 + $3 = $20 Total $20 + $8.50 = $28.50

  • A mango costs $0.90 and a pear costs $0.70. Maggie bought a total of 14 mangoes and pears and paid $11.60. How many mangoes did she buy?

    Assume all 14 fruits bought were pears.

    Cost of 14 pears 14 x $0.70 = $9.80

    Excess money $11.60 - $9.80 = $1.80

    Difference in cost of each fruit $0.90 - $0.70 = $0.20

    Number of mangoes $1.80 $0.20 = 9 Maggie bought 9 mangoes.

    Check!!! Cost of 9 mangoes 9 x $0.90 = $8.10 Cost of 5 pear 5 x $0.70 = $3.50 Total $8.10 + $3.50 = $11.60
