Answer Key: Primary 4 Mathematics Quiz - Multiplication Division

Total Marks: 40


Section A: Multiple-Choice Questions (5 marks)

1. B) 1,170

  • Working: 234 × 5 = (200 × 5) + (30 × 5) + (4 × 5) = 1,000 + 150 + 20 = 1,170
  • Mark: 1 mark for correct answer.
  • Teaching Note: When multiplying a 3-digit number by a 1-digit number, multiply each digit starting from the ones place. 4 ones × 5 = 20 ones (write 0, carry 2 tens); 3 tens × 5 = 15 tens + 2 tens = 17 tens (write 7, carry 1 hundred); 2 hundreds × 5 = 10 hundreds + 1 hundred = 11 hundreds = 1,170.

2. A) 432

  • Working: 3,456 ÷ 8 = 432. 8 × 432 = 3,456.
  • Mark: 1 mark for correct answer.
  • Teaching Note: Use long division: 8 goes into 34 (hundreds) 4 times (32), remainder 2; bring down 5 to make 25 tens; 8 goes into 25 3 times (24), remainder 1; bring down 6 to make 16 ones; 8 goes into 16 2 times (16), remainder 0. Answer: 432.
  • Common Mistake: Students may forget to bring down the remainder.

3. B) 210

  • Working: 1,260 ÷ 6 = 210.
  • Mark: 1 mark for correct answer.
  • Teaching Note: This is a division problem: total eggs ÷ eggs per box = number of boxes. 1,260 ÷ 6 = 210.

4. A) 45 × 10 + 45 × 2

  • Working: 45 × 12 = 45 × (10 + 2) = (45 × 10) + (45 × 2) = 450 + 90 = 540.
  • Mark: 1 mark for correct answer.
  • Teaching Note: This uses the distributive property of multiplication over addition. When multiplying by a 2-digit number, you can break it into tens and ones.

5. C) 168

  • Working: 7 × 24 = 168.
  • Mark: 1 mark for correct answer.
  • Teaching Note: Total chairs = number of rows × chairs per row = 7 × 24 = 168.
