TuitionGoWhere Practice Paper — Answer Key

Mathematics Primary 1 | Practice Paper 1 — Numbers (Whole Numbers up to 100)

Section A: Counting and Number Recognition (10 marks)

1. Count the stars below. How many stars are there altogether? [2 marks]

Working:

  • Row 1: 5 stars
  • Row 2: 5 stars
  • Row 3: 3 stars
  • Total: 5 + 5 + 3 = 13 stars

✅ Answer: 13 stars

📝 Marking note: Award 2 marks for the correct answer. Award 1 mark if the student counts correctly but makes a minor addition error.

2. Write the number "thirty-five" in numerals. [2 marks]

Working:

  • "Thirty" = 30
  • "Five" = 5
  • Thirty-five = 30 + 5 = 35

✅ Answer: 35

📝 Marking note: Award 2 marks for correct numeral. Award 0 marks for "305" or "53" — common reversals to watch for.

3. Count the apples in each group. Write the number. [2 marks]

Working:

  • Each row has 10 apples.
  • There are 6 rows.
  • Total: 10 + 10 + 10 + 10 + 10 + 10 = 60

✅ Answer: 60

📝 Marking note: Award 2 marks for correct answer. Award 1 mark if the student writes 6 (counting rows instead of apples) — this is a common error.

4. What number comes just after 49? [2 marks]

Working:

  • "Just after" means the next number.
  • 49 + 1 = 50

✅ Answer: 50

📝 Marking note: Award 2 marks for correct answer. Some students may write 40 — check understanding of "after" vs "before".

5. What number comes just before 70? [2 marks]

Working:

  • "Just before" means the number that comes earlier.
  • 70 − 1 = 69

✅ Answer: 69

📝 Marking note: Award 2 marks for correct answer. Some students may write 71 — check understanding of "before".

Section B: Place Value and Comparing Numbers (10 marks)

6. What is the value of the digit 5 in the number 52? [2 marks]

Working:

  • In 52, the digit 5 is in the tens place.
  • The value of 5 in the tens place = 5 × 10 = 50

✅ Answer: 50

📝 Marking note: Award 2 marks for correct answer. Award 0 marks if the student answers "5" — this confuses the digit with its value.

7. How many tens and how many ones are in the number 63? [2 marks]

Working:

  • 63 = 6 tens + 3 ones
  • The digit 6 is in the tens place → 6 tens
  • The digit 3 is in the ones place → 3 ones

✅ Answer: 6 tens and 3 ones

📝 Marking note: Award 2 marks for both correct. Award 1 mark if only one part is correct.

8. Which number is smaller, 88 or 78? [2 marks]

Working:

  • Compare the tens digit: 8 tens vs 7 tens.
  • 7 tens is less than 8 tens.
  • So 78 is smaller than 88.

✅ Answer: 78

📝 Marking note: Award 2 marks for correct answer. This checks understanding of comparing two-digit numbers.

9. Arrange these numbers from smallest to biggest: 45, 23, 67. [2 marks]

Working:

  • Compare all three numbers: 23, 45, 67
  • 23 < 45 < 67
  • Smallest to biggest: 23, 45, 67

✅ Answer: 23, 45, 67

📝 Marking note: Award 2 marks for all three in correct order. Award 1 mark if two numbers are in the correct relative position.

10. Fill in the blank with >, <, or =.   56 _____ 65 [2 marks]

Working:

  • Compare tens digits: 5 tens vs 6 tens.
  • 5 tens is less than 6 tens.
  • So 56 is less than 65.
  • Symbol: <

✅ Answer: <

📝 Marking note: Award 2 marks for correct symbol. Award 0 marks if the student uses ">" — check that they understand the symbol direction.

Section C: Number Patterns and Ordinal Numbers (10 marks)

11. Continue the pattern. Write the next two numbers: 10, 20, 30, 40, ______, ______. [2 marks]

Working:

  • The pattern increases by 10 each time.
  • 40 + 10 = 50
  • 50 + 10 = 60

13. Fill in the missing number: 55, 60, ______, 70, 75. [2 marks]

Working:

  • The pattern increases by 5 each time.
  • 60 + 5 = 65

Common Mistakes to Watch For

MistakeQuestion(s)What to Reinforce
Confusing digit with its value (answering "5" instead of "50")Q6Emphasise place value: the digit tells you how many, the place tells you what kind (tens or ones)
Reversing digits when writing number words (e.g., writing "305" for thirty-five)Q2Practice writing number words and matching them to numerals
Confusing "before" and "after"Q4, Q5Use a number line to show the direction of "before" (left) and "after" (right)
Using the wrong comparison symbol directionQ10Teach the "alligator mouth" — the open side faces the bigger number
Subtracting instead of adding in word problemsQ16Key words: "more" → add, "left" / "away" → subtract
