Unlock the Problem
Mark bought 6 new fish for his aquarium. He paid $7 for each fish. How much did he spend in all?

Find 6 × $7

  • Describe the groups in this problem.
  • Circle the numbers you will use to solve the problem.

You can use the Distributive Property to solve the problem.

The Distributive Property states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products.

Remember

sum—the answer to an addition problem
addends—the numbers being added

What other ways could you break apart the 6 × 7 array?
Answer:
Other ways could you break apart the 6 × 7 array:
6 × 7 = (6 × 4) + (6 × 3)
6 × 7 = (6 × 5) + (6 × 2)
6 × 7 = (6 × 1) + (6 × 6)

Explanation:
Other ways could you break apart the 6 × 7 array
6 × 7 = (6 × 4) + (6 × 3)
= 24 + 16
= 42.
6 × 7 = (6 × 5) + (6 × 2)
= 30 + 12
= 42.
6 × 7 = (6 × 1) + (6 × 6)
= 6 + 36
= 42.

Question 5.
H.O.T. Sense or Nonsense? Robin says, “I can find 8 × 7 by multiplying 3 × 7 and doubling it.” Does her statement make sense? Justify your answer.
Answer:
Her statement makes sense because 8 × 7 = (3 × 7) + (3 × 7) + (2 × 7) = 56.

Explanation:
8 × 7  = (3 + 3 + 2) × 7
= (3 × 7) + (3 × 7) + (2 × 7)
= 21 + 21 + 14
= 42 + 14
= 56.

H.O.T. Multi-Step Brandon needs 8 boxes of spinners for his fishing club. The cost of each box is $9. How much will Brandon pay?
Texas Go Math Grade 3 Lesson 7.4 Answer Key 11
8 × $9 = ___
Answer:
Amount of money Brandon needs to pay = $72.

Explanation:
Number of boxes of spinners for his fishing club Brandon needs = 8.
Cost of each box = $9.
Amount of money Brandon needs to pay = Number of boxes of spinners for his fishing club Brandon needs × Cost of each box
= 8 × $9
= $72.

Look at how Brandon solved the problem.
Find and describe his error.

8 × 9 = (4 × 9) + (5 × 9)
8 × 9 = 36 + 45
8 × 9 = 81

Texas Go Math Grade 3 Lesson 7.4 Answer Key 12

Use the array to help solve the problem and correct Brandon’s error.

8 × 9 = (4 + 4) × 9
8 × 9 =(___ × ___) + (__ × ___)
8 × 9 = ___ × ___
8 × 9 = ____

Texas Go Math Grade 3 Lesson 7.4 Answer Key 13
So, Brandon will pay $___ for the spinners.
Answer:
So, Brandon will pay $72 for the spinners.

Explanation:
8 × 9 = (4 × 9) + (5 × 9)
8 × 9 = 36 + 45
8 × 9 = 81.
Brandon mistake:
8 × 9 = (4 + 4) × 9 not (4 + 5) × 9.
Number of boxes of spinners for his fishing club Brandon needs = 8.
Cost of each box = $9.
Amount of money Brandon needs to pay = Number of boxes of spinners for his fishing club Brandon needs × Cost of each box
= 8 × $9
= (4 + 4) × 9
= (4 × $9) + (4 × $9)
= $36 + $36
= $72.

Lesson 7.4 Distributive Property Answer Key Go Math Grade 3 Question 8.
At a grocery store, the cans of nuts are arranged in 9 rows. There are 6 cans in each row. Which shows one way to find the total number of cans of nuts?
(A) (5 + 4) × 6
(B) (3 + 3) × 6
(C) (5 + 5) × 6
(D) (5 + 3) × 6
Answer:
Total number of cans of nuts = 54.
(A) (5 + 4) × 6.

Explanation:
Number of rows of cans of nuts are arranged in = 9.
Number of cans in each row = 6.
Total number of cans of nuts = Number of rows of cans of nuts are arranged in × Number of cans in each row
= 9 × 6
= (5 + 4) × 6
= (5 × 6) + (4 × 6)
= 30 + 24

Question 9.
Multi-Step Jillian bought 6 books for $7 each. She paid with $50. How much change should Jillian receive?
(A) $37
(B) $18
(C) $43
(D) $8
Answer:
Amount of change Jillian receives = $8.
(D) $8.

Explanation:
Number of books Jillian bought = 6.
Cost of each book = $7.
Amount of money she paid = $50.
Total amount of books Jillian bought = Number of books Jillian bought × Cost of each book
= 6 × $7
= (3 + 3) × $7
= (3 × $7) + (3 × $7)
= $21 + $21
= $42.
Amount of change Jillian receives = Amount of money she paid – Total amount of books Jillian bought
= $50 – $42
= $8.
