Primary 4 Mathematics
Sat, 15 Feb 2014 West View Primary School
Overview
O Transition from Primary 3 to Primary 4
O Examination Format
O Heuristics Skills
Transition from P3 to P4
The Differences Primary 3 Primary 4
Starting to test pupils on 2 steps
word problems
More questions of 3 to 4 steps
word problems and more heuristic
questions are added.
Topics tested on problem sums
include whole numbers and
Fractions
Topics tested on problem sums
include whole numbers and
Fractions
Basic Heuristics tested:
Comparison and Part-Whole model
Other heuristics:
Systematic list,
Unchanged total (eg. How many
apples must A give B so that they
have equal number of apples?)
and ….

2 ESSENTIAL TRAITS REQUIRED (PAPER 1)
1. SPEED
2. ACCURACY
Strategies for Section A & B Read and understand the question
Basic skills: Four operations
Build up pupils’ Number sense and Fraction sense e.g half of ½ is ¼. 2 halves make 1 whole)
Complete within given time. No time for checking (Must get it right the first time) A1 is given so unless necessary, need not show workings.
Shading of answer in OAS
Check: reasonableness, working
Sample Questions of Paper 1 For Section A (1-mark MC Question)
Round off 8 459 to the nearest hundred.
(1) 8 400
(2) 8 450
(3) 8 460
(4) 8 500
Sample Questions of Section A 2marks)
For Bk A >> Q 11 to Q 15 (2-mark MC Question )
Seng Woon Egg Farm delivers 260 cartons of eggs every morning. There are 24 eggs in each carton. How many eggs are delivered in a morning? (1) 1560 (2) 2080 (3) 5040 (4) 6240
Strategies for Section C Read and understand the PROBLEM
Apply heuristics: Model drawing, etc.
‘Convincing’ Presentation of solutions e.g Show operations as methods marks are given for the CORRECT use of Operations (+ - X, ÷)
Check: reasonableness, units
Section C – Marks Deduction
O Absence of Mathematical unit in
answer : Minus A½
(For 3, 4 and 5 marks questions only)
Eg : cm, m, km, g, kg, ⁰, etc.
O Wrong Mathematical Statement :
Minus M½ mark
(For 4 and 5 marks questions only)
Eg : 1 – 50 = 50
100 + 20 = 120 – 5 = 105 etc
Marks Deduction
O Did not simplify fractions to the
simplest form when the question
requests.
Eg : 6
12, 3
9
O Misconceptions : Assume 1.45 hour is
equal to 1 hour 45 minutes
Method Marks will be awarded for working shown clearly in Section C (problem sums)
Heuristics Skills 1. Part-Whole Model (same quantity)
2. Comparison Model (2 different
quantities)
3. Repeated Identity
4. Unchanged quantity
5. Systematic Listing/Guess and Check
6. Unchanged Total
7. Unchanged Difference
8. Equal Concept
Learn in P3
Example of presentation
John bought 120 sweets. He kept 1
4 of them
for himself and gave 1
3 of the remaining sweets
to some children. How many sweets did he
give away?
John
Gave
away? 4 units = 120
1 unit (give away)
= 120÷4
= 30 120
Actual Question
Mathematical
representation
Workings
Word sentence Answer Blank
with units
P4 Maths O Maths Course book
O Maths Activity Books (Some activities are
optional)
O Topical Worksheets (Last few questions /
more difficult questions are optional for 4A
– 4E)
O Heuristic Worksheets (2 WS per term)
O Mental Sums (Once a week, running revision
of quick calculations and basic concepts
O Intervention WS/ Drilling WS (At teachers’
discretion)
O Practice papers

How to revise for exam?
- Practise Section B and C problem sums in
practice papers. Do the sums. Don’t just read.
- Study teachers’ diagnostic marking. Check position
of ticks and crosses, common mistakes and
misconceptions
