Answer Key and Marking Scheme

Version: 2 of 5
Total Marks: 50

Section A: Choose the Correct Answer (1 mark each)

Question	Answer	Working/Explanation
1	B) 60	When counting, the number after 59 is 60. Think: 58, 59, 60. "After" means the next number going up.
2	B) 70	In 74, the digit 7 is in the tens place. The value of 7 in the tens place is $7 \times 10 = 70$ . Common mistake: Choosing A (7) confuses the digit with its place value.
3	B) 38	Compare tens first: 38 has 3 tens; 83 has 8 tens. Since $3 < 8$ , we know $38 < 83$ . So 38 is smaller.
4	C) 16	Count the stars one by one: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16. Strategy: Mark each star as you count to avoid double-counting.
5	C) 45 < 54	Compare tens: 45 has 4 tens; 54 has 5 tens. Since $4 < 5$ , we have $45 < 54$ . The symbol "<" means "is less than."
6	A) 58	The pattern counts up by 1: 55, 56, 57, 58, 59. The missing number is 58.
7	B) 63	6 tens = $6 \times 10 = 60$ ; 3 ones = $3 \times 1 = 3$ . Altogether: $60 + 3 = 63$ .
8	B) E	Count from the left: 1st = A, 2nd = B, 3rd = C, 4th = D, 5th = E. Ordinal numbers tell position.
9	B) 17, 27, 72	Compare tens: 17 has 1 ten (smallest), 27 has 2 tens, 72 has 7 tens (biggest). So: 17 < 27 < 72.
10	A) 47	4 tens = 40; 7 ones = 7. Number = $40 + 7 = 47$ .

Section A Total: 10 marks

Section B: Write Your Answers (2 marks each)

11. 73 (2 marks)

"Seventy" means 70 (7 tens)
"Three" means 3 (3 ones)
$70 + 3 = 73$

Marking: 2 marks for correct answer. Deduct 1 mark if written as "703" (confusing place value).

12. 15 apples (2 marks)

Group 1: 8 apples
Group 2: 7 apples
Altogether: $8 + 7 = 15$

Strategy: Count each group separately, then add. Can also count all objects from 1 to 15.

Marking: 2 marks for correct answer with reasoning shown; 1 mark for correct final answer without visible working.

13. 52 (2 marks)

Digits available: 5 and 2
Two possibilities: 52 or 25
For biggest number, put larger digit in tens place: 52
Check: $52 > 25$

Marking: 2 marks for correct answer; 1 mark if answer is 25 (shows understanding of two-digit formation but wrong objective).

14. 16, 22 (2 marks)

Pattern: counting up by 2 (even numbers)
12, 14, 16, 18, 20, 22, 24
Working: $14 + 2 = 16$ ; $20 + 2 = 22$

Marking: 1 mark for each correct answer.

15. Tom has more stickers; 9 more (2 marks)

Tom: 43 stickers; Jerry: 34 stickers
Compare: 43 > 34 (both have 4 and 3, but 43 has 4 tens vs 3 tens, so 43 > 34)
How many more: $43 - 34 = 9$

Marking: 1 mark for "Tom"; 1 mark for "9 more". Deduct 1 mark if only one part correct.

16. 91, 90, 19, 9 (2 marks)

Compare tens place first: 91 and 90 both have 9 tens (biggest group)
Then 19 has 1 ten; 9 has 0 tens (smallest)
Between 91 and 90: $91 > 90$ (same tens, compare ones: $1 > 0$ )

Marking: 2 marks for fully correct order; 1 mark if reverse order (smallest to biggest) or one number out of place.

Section B Total: 12 marks

Section C: Problems and Working (7 marks each)

17. (7 marks total)

(a) 100 beads (2 marks)

10 rows × 10 beads per row = total beads
$10 \times 10 = 100$
Working: $10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 + 10 = 100$

Marking: 2 marks for correct answer with multiplication or repeated addition shown.

(b) 75 beads (3 marks)

Start with: 100 beads
Taken out: 25 beads
Left: $100 - 25 = 75$

Step-by-step:

$100 - 20 = 80$
$80 - 5 = 75$

Marking: 1 mark for correct method; 1 mark for correct subtraction steps; 1 mark for final answer.

(c) Yes, 15 beads in each bag (2 marks)

Remaining beads: 75
Divide by 5 bags: $75 \div 5 = 15$

Check: $5 \times 15 = 75$ ✓

Marking: 1 mark for correct division method; 1 mark for correct answer with verification.

18. (7 marks total)

Expected table features: 3×3 grid with numbers 23, 45, 67 (top row); 32, 54, 76 (middle row); 89, 91, 18 (bottom row)

(a) 23 and 32 should be circled (2 marks)

"2 tens" means the digit in tens place is 2
23: 2 tens and 3 ones ✓
32: 3 tens and 2 ones ✗ (this has 3 tens, not 2)
Correction: Only 23 has exactly 2 tens

Re-evaluation: Let me recheck.

23: 2 tens, 3 ones ✓
32: 3 tens, 2 ones ✗

Answer: 23 (2 marks)

Marking: 2 marks for circling only 23; 1 mark if 32 also circled (confuses digit with place value).

(b) Ninety-one (2 marks)

Compare all numbers: 23, 45, 67, 32, 54, 76, 89, 91, 18
Largest: 91 (9 tens, which is more than any other number's tens)
In words: ninety-one

Marking: 1 mark for identifying 91; 1 mark for correct spelling in words.

(c) 18; eighteen (2 marks)

Smallest: 18 (1 ten and 8 ones, smallest tens digit)
In numerals: 18
In words: eighteen

Marking: 1 mark for numerals; 1 mark for words.

(d) 5 numbers (1 mark)

Numbers bigger than 50: 67, 54, 76, 89, 91
Count: 67 (✓), 54 (✓), 76 (✓), 89 (✓), 91 (✓) → 5 numbers

Marking: 1 mark for correct count; allow follow-through if (b) error made but method consistent.

19. (7 marks total)

(a) 4 (2 marks)

Houses numbered 1, 2, 3, 4, 5, 6, 7 along the street
4th from left: 1st, 2nd, 3rd, 4th → house number 4

Marking: 2 marks for correct answer. 1 mark if answer is "house 4" but position described incorrectly.

(b) 7 houses (2 marks)

From house 1 to house 7, you pass: house 1, 2, 3, 4, 5, 6, 7
Total: 7 houses

Common mistake: Answering 6 (counting gaps, not houses).

Marking: 2 marks for correct answer; 1 mark for method showing list of houses.

(c) 2, 4, 6 (3 marks)

Even numbers: numbers ending in 0, 2, 4, 6, 8
From 1–7: check each: 1 (odd), 2 (even), 3 (odd), 4 (even), 5 (odd), 6 (even), 7 (odd)
Yellow houses: 2, 4, 6

Marking: 1 mark for recognizing even numbers; 1 mark per two correct answers; 3 marks for all three correct.

20. (7 marks total)

(a) 7 (2 marks)

Ones digit = 2 (given)
Tens digit = ones digit + 5 = $2 + 5 = 7$

Marking: 2 marks for correct answer; 1 mark for correct method with arithmetic error.

(b) 72 (2 marks)

Tens digit: 7; Ones digit: 2
Number = $70 + 2 = 72$

Marking: 1 mark for correct digits; 1 mark for correct place value combination.

(c) 82 (3 marks)

Number: 72
10 more than 72: $72 + 10 = 82$

Method:

10 more means add 1 ten
72 has 7 tens and 2 ones
Add 1 ten: 8 tens and 2 ones = 82

Working: $72 + 10 = 82$ or $70 + 10 + 2 = 82$

Marking: 1 mark for understanding "10 more"; 1 mark for correct addition method; 1 mark for final answer.

Common Error Summary

Error Type	Prevention Tip
Confusing digit and value (e.g., saying "7" instead of "70")	Always ask: "Where is the digit? What place is it in?"
Counting gaps instead of objects	Touch or mark each object as you count it
"After" vs "before"	"After" = next number up; "Before" = number just before
Comparing without checking tens first	Always compare the tens digit first, then ones if tens are equal
Writing numbers as words	Break into tens part + ones part, then join
