Answer key for parents & teachers (57 questions)
  1. What does 3 × 4 mean? — 3 groups of 4. 3 × 4 means 3 groups of 4 — the same as 4 + 4 + 4!
  2. What is the product in a multiplication problem? — The answer. The PRODUCT is the answer you get when you multiply two factors!
  3. What are FACTORS in a multiplication problem? — The two numbers being multiplied. FACTORS are the two numbers being multiplied. In 4 × 5 = 20, the factors are 4 and 5.
  4. Which is the same as 5 + 5 + 5 + 5? — 4 × 5. 5 added 4 times = 4 × 5 = 20!

  15. What is 18 ÷ 6? — 3. 18 ÷ 6 = 3. Check: 6 × 3 = 18!
  16. What is the QUOTIENT in a division problem? — The answer. The QUOTIENT is the answer to a division problem!
  17. What is the DIVIDEND in 28 ÷ 7? — 28. The DIVIDEND is the number being divided. In 28 ÷ 7 = 4, the dividend is 28.
  18. What is the DIVISOR in 28 ÷ 7? — 7. The DIVISOR is the number you divide by. In 28 ÷ 7 = 4, the divisor is 7.
  19. Division is the OPPOSITE of which operation? — Multiplication. Division is the opposite (inverse) of multiplication!
  20. 15 cookies are shared equally among 3 friends. How many does each get? — 5. 15 ÷ 3 = 5. Each friend gets 5 cookies!
  21. What is 100 ÷ 10? — 10. 100 ÷ 10 = 10. Ten groups of 10 make 100!
  22. If 9 × 6 = 54, what is 6 × 9? (Commutative Property) — 54. The Commutative Property says a × b = b × a. 6 × 9 = 9 × 6 = 54!
  23. What does the Commutative Property of multiplication say? — The order of factors does not change the product. Commutative Property: a × b = b × a. The ORDER of factors does not matter!
  24. What does the Associative Property of multiplication say? — Grouping of factors does not change the product. Associative Property: (a × b) × c = a × (b × c). GROUPING does not matter!
  25. What does the Distributive Property say? — a × (b + c) = (a × b) + (a × c). Distributive Property: a × (b + c) = (a × b) + (a × c). You can BREAK a factor apart!
  26. (2 × 3) × 4 = 2 × (3 × 4). Which property is this? — Associative. Regrouping factors without changing the product = Associative Property!
  27. What is any number multiplied by 0? — 0. Any number × 0 = 0. Zero groups of anything is zero!
  28. Use the Commutative Property. If 7 × 8 = 56, what do you know for free? — 8 × 7 = 56. Commutative: 7 × 8 = 8 × 7 = 56. You get that fact for free!
  29. Which property explains why knowing 4 × 9 automatically tells you 9 × 4? — Commutative. The COMMUTATIVE Property: 4 × 9 = 9 × 4. Order does not change the product!
  30. Which is true? a × 0 = 0 for ANY number a. — True — Zero Property. True — Zero Property of Multiplication: any number multiplied by 0 equals 0!
  31. What is 8 × 7? — 56. 8 × 7 = 56. Use: (8 × 5) + (8 × 2) = 40 + 16 = 56!
