Early preparations• Pen and common stationery• A scientific calculator• 2B pencils• A soft eraser• A 30cm long transparent plastic ruler• Geometry set – a compasses, a protractor and
a set square• Graph paper• Text book / revision series• Authentic SPM examination papers starting
2003
Basic skills needed for SPM• The multiplication table from 1 to 9• The basic 4 operations of +, - , x and ÷• Computations in whole numbers, fractions
and decimals • Computations involving the basic
measurement ( length, mass and time )• Simple constructions• Organizing structured data and concluding
skill• Systematic presentation according to fixed
algorithm and procedures
Effective methods in studying mathematics• Give full attention when the teacher is teaching• Understand the relevant Mathematics concepts• Understand the calculations involved via samples
calculations• Apply similar skills in different situation• Memorize the formula• Have enough practice by doing lots of exercises from
each topic• Have lots of drilling exercises including past year
questions (at least for 5 most recent years)
General strategies for answering mathematics• Read every question carefully.• Answer the easy question first. Attempt
the difficult ones later. Use the extra time to check your answer.
• Answer based on the task words.• Give the correct answer.• Simplify the answer.• Use the mathematical instrument such
as geometry set if needed.
Students common mistake
1. Solve y2 – 4y = 12Incorrect
y2 – 4y = 12y ( y – 4 ) = 12y = 12,
y – 4 = 12y = 16
Correct
y2 – 4y = 12y2 – 4y – 12 = 0( y + 2 ) ( y – 6 ) = 0y = -2 , y = 6
2. Factorise completely 4x2 – 9
Incorrect
4x2 – 9= (2x)2 – 32
= (2x – 3)2
Correct
4x2 – 9= (2x)2 – 32
= (2x – 3)(2x + 3)
3. Round off 4952 correctto two significant figures
Incorrect
4952
= 50
Correct
4952
= 5 000
4. Determine whether the mathematical sentence is a statement. Give the reason.
‘ 5 X 3 = 8 ‘
Incorrect
Is not a statement.
Correct
A statement.
Complete the following argument.P1 : If x – 7 = 11, then x = 18.p2 : x ≠ 18C : ____________________Incorrect
Not x – 7 = 11
Correct
x – 7 ≠ 11
State the y-intercept of the straight line LK
Incorrect
y-intercept = (0,5)
Correct
y-intercept = 5
Incorrect

Given that sin x = 0.5219, find the value of xIncorrect
sin x = 0.5
x = 30°
Correct
sin x = 0.5219
x = 31° 28’
