Answer key for parents & teachers (24 questions)
  1. What does "3 times as many as 7" mean? — 3 × 7 = 21. "3 times as many as 7" means 3 × 7 = 21.
  2. Sam has 8 stickers. Mia has 4 times as many. How many does Mia have? — 32. 4 × 8 = 32. Mia has 32 stickers.
  3. Which equation matches: "A is 6 times as many as B"? — A = 6 × B. Multiplicative comparison: A = 6 × B.
  4. A cat weighs 5 kg. A dog weighs 3 times as much. How much does the dog weigh? — 15 kg. 3 × 5 = 15 kg.
  5. Leo picked 24 apples. Ana picked 6 apples. How many times as many did Leo pick? — 4 times. 24 ÷ 6 = 4. Leo picked 4 times as many.
  6. A red rope is 12 m. A blue rope is 2 times as long. How long is the blue rope? — 24 m. 2 × 12 = 24 m.
  7. "Additive comparison" answers which question? — How many more?. Additive comparison asks "how many more (or fewer)?" using subtraction.
  8. Tom has 5 cards. Jerry has 35 cards. Which statement is true? — Jerry has 7 times as many. 35 ÷ 5 = 7. Jerry has 7 times as many.
  9. What is a factor? — A number that divides evenly into another. A factor divides evenly into another number with no remainder.
  10. Which number is a factor of 20? — 4. 20 ÷ 4 = 5 exactly, so 4 is a factor of 20.
  11. How many factors does a prime number have? — 2. A prime number has exactly 2 factors: 1 and itself.
  12. Is 1 prime, composite, or neither? — Neither. 1 has only one factor (itself), so it is neither prime nor composite.
  13. Which is the only even prime number? — 2. 2 is the only even prime — all other even numbers are divisible by 2, making them composite.
  14. How many factor pairs does 16 have? — 3. Factor pairs of 16: 1×16, 2×8, 4×4 — that is 3 factor pairs.
  15. Which set lists ALL factors of 10? — 1, 2, 5, 10. 10 = 1×10 = 2×5. All factors: 1, 2, 5, 10.
  16. A composite number has how many factors? — More than 2. A composite number has more than 2 factors.
  17. What is the rule for the pattern: 5, 10, 15, 20, 25? — Add 5. Each term is 5 more than the last: 5+5=10, 10+5=15, etc. Rule: add 5.
  18. What is the next number? 3, 6, 9, 12, ___ — 15. Add 3 each time: 12 + 3 = 15.
  19. What is the rule? 2, 6, 18, 54 — Multiply by 3. 2×3=6, 6×3=18, 18×3=54. Rule: multiply by 3.
  20. Which pattern has a rule of "subtract 4"? — 20, 16, 12, 8. 20−4=16, 16−4=12, 12−4=8. Rule: subtract 4.
  21. What is the 6th term? 1, 2, 4, 8, 16, ___ — 32. Rule: multiply by 2. 16×2=32.
  22. Fill in: 8, ___, 24, 32, 40 — 16. Rule: add 8. 8+8=16, 16+8=24. Missing term is 16.
  23. What type of pattern is: 1, 4, 9, 16, 25? — Perfect squares (n²). 1²=1, 2²=4, 3²=9, 4²=16, 5²=25. These are perfect squares!
  24. In the pattern 100, 90, 80, 70, ___, the missing term is: — 60. Rule: subtract 10. 70−10=60.
