Question 1
What is 4 × 60?
Correct answer: A
4 × 6 = 24, so 4 × 6 tens = 24 tens = 240. 2,400 has one zero too many.
-
Question 2
Which expression is equal to 7 × 8?
Correct answer: D
Split 8 into 5 + 3 and multiply both parts by 7: 35 + 21 = 56 = 7 × 8. In (7 × 5) + 3, the 3 was never multiplied by 7.
-
Question 3
Which expression has the same product as 3 × 2 × 5?
Correct answer: B
You can multiply in any grouping: 3 × (2 × 5) = 3 × 10 = 30. 6 + 5 adds the last factor instead of multiplying it.
-
Question 4
What number makes this equation true?
☐ × 8 = 8 × 7Correct answer: C
Changing the order of the factors does not change the product, so 7 × 8 = 8 × 7. 56 is the product, not the missing factor.
-
Question 5
Look at the products in the 4s facts: 4, 8, 12, 16, 20, 24, … Which statement is always true about a whole number multiplied by 4?
Correct answer: D
Multiplying by 4 is the same as doubling twice, and a double is always even. 12 and 16 show that the product does not always end in 4 or 0.
-
Question 6
What is 5 × 70?
Correct answer: A
5 × 7 = 35, so 5 × 7 tens = 35 tens = 350. 75 adds 5 to 70 instead of multiplying.
-
Question 7
What number makes this equation true?
☐ × 30 = 180Correct answer: C
6 × 3 = 18, so 6 × 30 = 180. 60 × 30 would be 1,800, which is ten times too large.
-
Question 8
What is 0 × 486?
Correct answer: B
Any number multiplied by 0 is 0, because 0 groups of 486 is nothing. 486 is the answer for 1 × 486.
-
Question 9
Ella finds 8 × 6 by splitting it into 8 × 2 and 8 × 4. Which sum does she add?
Correct answer: D
8 × 2 = 16 and 8 × 4 = 32, and 16 + 32 = 48 = 8 × 6. 10 + 12 adds 8 + 2 and 8 + 4 instead of multiplying.
-
Question 10
Look at these products: 9, 18, 27, 36, 45. Which rule describes the digits?
Correct answer: B
From 18 to 27 to 36, the tens digit goes 1, 2, 3 and the ones digit goes 8, 7, 6. This happens because adding 9 is the same as adding 10 and taking away 1.
