Total Marks: 20


Section A — Counting and Place Value (5 marks)

Q1. 12

  • 1 mark: Correct count of 12 apples.
  • Teaching note: Children should count each apple once. Encourage touching each item as they count to keep track.
  • Common mistake: Saying "eleven" or "thirteen" because the last item is skipped or counted twice.

Q2. 40

  • 1 mark.
  • Teaching note: "Just after" means the next counting number. 39 is the same as three tens and nine ones; the next number is three tens and ten ones = 4 tens = 40.

Q3. 74

  • 1 mark.
  • Teaching note: "Just before 75" means one less than 75. 75 = 7 tens 5 ones, so one less is 7 tens 4 ones = 74.

Q4. 64

  • 1 mark.
  • Teaching note: Read the tens place first (6 tens = 60), then the ones place (4 ones), then combine: 60 + 4 = 64.

Q5. 5 ones (or 5)

  • 1 mark. Full credit for "5 ones"; "5" alone may also be accepted depending on marking policy.
  • Teaching note: In 58, the digit 5 is in the tens place. Its value is 5 tens = 50.
  • Common mistake: Saying "5 tens" when the question asks for the value of the digit 5; both refer to the same idea here, but children may confuse the digit with the place. The value is 50.

Correction note: The mark scheme awards full credit for stating 5 tens = 50, which is the actual value of the digit 5 in 58. If a child writes "5 ones", that is incorrect for 58 (it would apply to 85).


Section B — Comparing and Ordering (5 marks)

Q6. >

  • 1 mark.
  • Teaching note: 53 has 5 tens, 35 has 3 tens. More tens means a larger number, so 53 > 35.

Q7. <

  • 1 mark.
  • Teaching note: 47 has 4 tens; 74 has 7 tens. 4 tens is less than 7 tens, so 47 < 74.

Q8. 19, 47, 62

  • 1 mark.
  • Teaching note: Compare tens first. 19 has 1 ten, 47 has 4 tens, 62 has 6 tens. So 1 ten < 4 tens < 6 tens.

Q9. 88, 55, 28

  • 1 mark.
  • Teaching note: Greatest to smallest. Tens: 88 (8), 55 (5), 28 (2). Largest tens first.

Q10. The triangle (at 70)

  • 1 mark.
  • Teaching note: Children read the number line. The symbol above the 70 mark is the triangle. The number line should show tick marks at every multiple of 10 with labels visible.
  • Visual requirement: The triangle must be clearly drawn at the 70 mark with the "70" label visible nearby.

Section C — Number Patterns and Sequences (4 marks)

Q11. 48

  • 1 mark.
  • Teaching note: The pattern increases by 2: 42 → 44 → 46 → 48 → 50.

Q12. 60

  • 1 mark.
  • Teaching note: The pattern decreases by 5: 75 → 70 → 65 → 60 → 55.

Q13. 50

  • 1 mark.
  • Teaching note: The pattern increases by 10: 20 → 30 → 40 → 50 → 60.

Q14. 35

  • 1 mark.
  • Teaching note: The pattern increases by 5. After 30, the next number is 35, then 40, then 45.

Section D — Ordinal Numbers (3 marks)

Q15. 3rd

  • 1 mark.
  • Teaching note: Ordinal numbers (1st, 2nd, 3rd, …) show position. The question gives Devi's position directly: 3rd.

Q16. 4 people

  • 1 mark.
  • Teaching note: Mei Ling is 5th. The people in front of her are 1st, 2nd, 3rd, 4th. That is 4 people. (She herself is not in front of her.)
  • Common mistake: Writing 5. There are 4 people in front, not 5.

Q17. The fish (4th position)

  • 1 mark.
  • Teaching note: Count the positions from left to right. 1st cat, 2nd dog, 3rd rabbit, 4th fish, 5th bird.
  • Visual requirement: The picture must clearly show the ordinal labels 1st–5th above each animal in a single row.

Section E — Numbers in Words (3 marks)

Q18. 46

  • 1 mark.
  • Teaching note: "Forty" is the tens word; "six" is the ones word. Write 46.

Q19. eighty-two

  • 1 mark. (Accept "eighty two" or "eighty-two".)
  • Teaching note: 82 = 8 tens and 2 ones → "eighty-two".
  • Spelling note: "Eight" + "y" = "eighty" (not "eightty").

Q20. (b) twenty-nine

  • 1 mark.
  • Teaching note: (a) 17 and (c) 64 are written in numerals (digits). (b) "twenty-nine" is written in words. The child must identify the option written in English words.
