Key Points to Note Paper 1: CALCULATORS NOT ALLOWED

Booklet A: 15 Multiple Choice Questions

Select answer from the 4 given options and shade selected option in the OAS.

Booklet B: 15 Short Answer Questions

To show workings clearly and write the correct answers in the spaces provided

For 2-mark questions, method marks are awarded for correct workings shown even if final answers are incorrect.

For questions with 2 parts, 2 marks are awarded for the correct answers. 1 mark for each part.

Answers must be given according to the Standard units of measurement provided on the answer blanks.
Paper 2: CALCULATORS ALLOWED

5 Short Answer Questions

To show workings clearly and write the correct answers in the spaces provided

Method marks are awarded for correct workings shown even if final answers are incorrect.

12 Problem Sums

To show each step taken (number equations) and solutions clearly so that method marks can be awarded accordingly

Method marks will be awarded for each correct significant step of the solutions even if the final answer is wrong.

Where applicable, standard units of measurement must be indicated with final answers.
Calculators

Only calculators approved by SEAB will be allowed for use in the examinations.

Approved list of calculators: https://www.seab.gov.sg/content/calculator/GuidelinesCalculators.pdf

To maintain continuity from primary to secondary education, these calculators can be used at the secondary level.

Problem Solving Heuristics

Commonly used:

Draw a model or diagram

Make a systematic list/ tabulation

Use before / after concept

Look for a pattern

Guess & Check

Work backwards

Supposition
25% of the boys in a hall is equal to 16% of the

girls. There are 72 more girls than boys. How

many children are there in the hall?

25%

16%

Boys

Girls 36%

72 25% 25% 25%

16% 16% 16%

36% of girls = 72

64% of girls = (72 36) x

64

= 128

128 x 2 + 72 = 328 Ans: 328

Presentation of Solutions

Wrong Mathematical

Statement/Presentation

*36% = 72

64% = 128
Presentation of Solutions

Things to Note:

Include units of measurement

x 100% = 60% (money spent)

3 kg x 4 = 12 kg (sugar used)

Use equal signs correctly

of total amount = $45 (used)

Clearly indicate the method of solution (working steps / number equations).

Write final answers on the answer lines provided.
