Answer Key and Marking Notes — Teacher’s Copy
Primary 5 Mathematics · First Term Test Practice Paper
Section A (16%, 2% each)
| Q | Answer | Working / marking note |
|---|---|---|
| 1 | 368 | 36 × 4 = 144; 512 − 144 |
| 2 | 9996 | 98 × 100 + 98 × 2 = 9800 + 196 |
| 3 | 45 | 4 × 25 = 100 first; 36 × 125 ÷ 100 = 4500 ÷ 100 |
| 4 | 6 1320 | 7.6 − 2.75 + 1.8 = 6.65; or L.C.M. 20 throughout |
| 5 | 49 | L.C.M. 36: 27 − 21 + 10 = 16, then 16/36 = 4/9 |
| 6 | 2 718 | 148/18 − 105/18 = 43/18 |
| 7 | 1 5960 | L.C.M. 60: 24 + 45 + 50 = 119/60 |
| 8 | 5 124 | 6 − 3 7/12 = 2 5/12; 2 10/24 + 2 15/24 = 4 25/24 |
Award the mark only if the answer is in its simplest form. An unsimplified answer (e.g. 16/36 in Q5) scores 0 for that item.
Section B (20%, 2% each)
| Q | Answer | Note |
|---|---|---|
| 1 | 0 | 604 738 — the ten-thousands digit is 0; accept only 0 |
| 2 | 34 | Divide the top and the bottom by 14 |
| 3 | 24 | 3 ÷ 1/8 = 24 |
| 4 | 1, 3, 5, 9, 15, 45 | All six needed; a missing or an extra factor scores 0 |
| 5 | 6 | 18 = 2 × 3², 24 = 2³ × 3 |
| 6 | 712, 34, 56 | L.C.M. 12: 7/12, 9/12, 10/12 |
| 7 | x = 38 | 4 2/9 = 38/9 |
| 8 | 85 302 | Largest digits first, but the units digit must be even (0 or 2) |
| 9 | NE | The reverse direction of SW |
| 10 | rhombus | Accept 菱形 / rhombus. Not «square» — a square has right angles |
Original questions by TutorZone. Paper format modelled on a Hong Kong primary school’s first-term mathematics test paper; this is not that school’s examination paper.
Section C (30%)
| Q | Answer | Working / marking note |
|---|---|---|
| 1(a) | S (south) · 2% | Facing east, a right turn is 90° clockwise → south |
| 1(b) | N (north) · 1% | The minute hand points at 12; with 3 o’clock pointing east, 12 points north |
| 2(a) | 8 · 1% | 2 diagonals + 2 mid-lines cut the square into 8 identical triangles |
| 2(b) | 38 · 2% | 3 shaded out of 8; must be simplified |
| 3 | Any two different parallelograms with base × height = 16 cm² | 4% = two correct figures with the base and the height labelled; 2% = only one correct; 0 = the same shape drawn twice |
| 4 | Perimeter 30 cm (2%) · Area 45 cm² (2%) | (9 + 6) × 2 ; 9 × 5. Using the slant side (6 cm) as the height in the area part scores 0 |
| 5 | 36 cm² · 3% | The figure has 8 square-edges exposed: 48 ÷ 8 = 6 cm; then 6 × 6 |
| 6 | 80 cm² · 3% | Large 15 × 6 = 90; small 5 × 2 = 10; 90 − 10 |
| 7 | 64 cm² · 3% | 40 + 40 − 16 (the overlap is 4 cm × 4 cm). Adding the overlap instead of subtracting it scores 0 |
| 8 | Two triangles of different shapes, each ½ × base × height = 12 | 4% = two correct triangles with the base and the height shown; 2% = one correct; the same shape twice = 0 |
| 9 | Perimeter 42 cm (1%) · Area 84 cm² (2%) | 13 + 14 + 15 ; 14 × 12 ÷ 2 |
Section D (10%, 2% each)
| Q | Answer | Note |
|---|---|---|
| 1 | 90 books | 40 + 50 |
| 2(a)(b) | Thursday; 65 books | Both parts are needed for the 2% |
| 3 | 245 books | 25 + 40 + 35 + 65 + 50 + 30 |
| 4 | Wednesday and Thursday | +30 books; the next largest rise is +15 |
| 5 | Any sensible reason | e.g. the library closes earlier on Saturday / fewer pupils come to school on Saturday |
Section E (24%, 4% each)
| Q | Answer | Working / marking note |
|---|---|---|
| 1 | Length 30 cm; area 540 cm² | 96 ÷ 2 − 18 = 30 ; 30 × 18 |
| 2 | 243 cm² | Base = 9 × 3 = 27 ; 27 × 9 |
| 3 | $1740 | 145 × 4 = 580 cm of lace ; 580 × $3 |
| 4 | $212 | Chicken $96 ÷ 3 = $32 ; 96 × 2 + 32 × 3 = 288 ; 500 − 288 |
| 5 | 4 112 hours | 4 1/4 + 2 2/3 = 6 11/12 ; 6 11/12 − 2 5/6 = 4 1/12 |
| 6 | 74 78 kg | Sister 38 3/4 − 2 5/8 = 36 1/8 ; 38 3/4 + 36 1/8 = 74 7/8 |
Section E marking: 1% for a correct statement/equation, 1% for the correct substitution, 1% for the correct numerical value, 1% for the correct unit. A correct answer with no working scores at most 2%, because the section instruction asks for statements and working steps.
Four places where marks are most often lost in this paper
| Trap | What the pupil writes | What should happen |
|---|---|---|
| Section A Q5 — the L.C.M. is 36, not 24 | Uses 24 → 18 − 14 + 6 = 10/24 | 12 and 18 share 36; 16/36 must be simplified to 4/9 |
| Section C Q4 — the slant side used as the height | (9 + 6) × 2 = 30 for the area | Area uses the perpendicular height: 9 × 5 = 45 cm² |
| Section C Q7 — the overlap double-counted or ignored | 40 + 40 = 80, or 40 + 40 + 16 | Subtract the overlap once: 40 + 40 − 16 = 64 cm² |
| Section E Q1 — the halving of the perimeter left out | 96 − 18 = 78 for the length | 96 ÷ 2 = 48 ; 48 − 18 = 30 cm for the length |
How to use this paper
① 45 minutes, no calculator, one sitting — Sections A and B about 13 minutes, Section C 15 minutes, Section D 5 minutes, Section E 12 minutes.
② Mark with the notes above; record «statement missing» and «unit missing» separately from «wrong answer».
③ Items lost in Sections A or B are concept gaps — redo three similar items before moving on. Items lost only in Section E are presentation gaps — practise writing the statement line first.
④ Redo the whole paper after seven days; the target is 90% or above on the second attempt.
四個最常失分位
- 在梯形／平行四邊形面積用了斜邊而不用高。
- 分數除法的商沒有約至最簡，或忘記「倒轉相乘」。
- 圓周與圓面積公式調亂（P5 只考圓的性質，不涉公式）。
- 應用題沒有寫出單位，或答案沒有寫成帶分數。
