SSPA Mock Exam (1) · Primary 5 Mathematics

Scope: Lessons 1–10 (Multiple Figures · Estimation · Area · Fractions)

Exam time: 50 minutes Full score: 100 points

Name: date: Fraction: / 100

═══════ Part A: Multiple choice questions ═══════

Part A - Multiple Choice Questions10 questions × 3 points = 30 points

Instructions: Choose the correct answer and fill in the letter of the answer in the space to the right of each question. There is only one correct answer for each question.

🎫 Exam tips (SSPA must read)

① Do the questions you know first, don’t get stuck on one!
② Check the unit for each question (cm vs cm² vs cm³)!
③ Geometry questions: If there is an elevation in the picture, use the height. If there is no elevation, use the formula to find it!
④ Application question: Write an answer sentence! Points will be deducted for not writing steps!
⑤ 5 minutes left: Check if the MC has been filled in and if the unit is correct!

Exam tips:
· Part A MC Trap: Question 3: Note that the triangle must be ÷2. Question 5: The hypotenuse is not high. Question 7: Unify the units first.
· Part B calculation questions: To get the general score, you must first find LCM, and the answer must be simplified
· Part C application questions: Each question has its own trap (combined graph segmentation, residual fraction benchmark, estimation vs. exact comparison)
· Make good use of 50 minutes: 12 minutes for Part A → 20 minutes for Part B → 15 minutes for Part C → 3 minutes for inspection
