Question 12.
Use Tools The table tells about quilt pieces Jenna has made. How many squares are there in 6 of Jenna’s quilt pieces?

Answer:
Number of squares in 6 of Jenna’s quilt pieces = 36.

Explanation:
Number of squares in one quilt pieces = 6.
Number of quilt pieces Jenna’s having = 6.
Number of squares in 6 of Jenna’s quilt pieces = Number of squares in one quilt pieces × Number of quilt pieces Jenna’s having
= 6 × 6
= 5 × 6 + 6
= 30 + 6
= 36.

 

Go Math Grade 3 Lesson 7.3 Answer Key Question 13.
Compare How many more squares than triangles are in 3 of Jenna’s quilt pieces?
Answer:
3 more squares than triangles are in 3 of Jenna’s quilt pieces.

Explanation:
Number of squares in one quilt pieces = 6.
Number of quilt pieces Jenna’s having = 3.
Number of squares in 3 of Jenna’s quilt pieces = Number of squares in one quilt pieces × Number of quilt pieces Jenna’s having
= 6 × 3
= 5 × 3 + 3
= 15 + 3
= 18.
Number of triangles in one quilt pieces = 4.
Number of quilt pieces Jenna’s having = 3.
Number of triangles in 3 of Jenna’s quilt pieces = Number of triangles in one quilt pieces × Number of quilt pieces Jenna’s having
= 4 × 3
= 3 × 3 + 3
= 9 + 3
= 12.
Difference:
Number of squares in 3 of Jenna’s quilt pieces – Number of triangles in 3 of Jenna’s quilt pieces
= 18 – 15
= 3.

 

Question 14.
H.O.T. Multi-Step Alii had some craft sticks. She decided to make shapes. If she used one craft stick for each side of the shape, would Alii use more craft sticks for 5 squares or 6 triangles? Explain.

Answer:
Alii use 2 more craft sticks for 5 squares than 6 triangles.

Explanation:
Number of craft stick for each side of the shape she used = 1.
Number of sides for a square = 4.
Number of craft sticks for making 5 squares = 5 × (Number of craft stick for each side of the shape she used × Number of sides for a square)
= 5 × (1 × 4)
= 5 × 4
= 4 × 4 + 4
= 16 + 4
= 20.
Number of sides for a triangle = 3.
Number of craft sticks for making 6 triangle = 6 × (Number of craft stick for each side of the shape she used × Number of sides for a triangle)
= 6 × (1 × 3)
= 6 × 3
= 18.
Difference:
Number of craft sticks for making 5 squares – Number of craft sticks for making 6 triangle
= 20 – 18
= 2.

H.O.T. Multi-Step Draw a picture and use words to explain the Commutative Property of Multiplication with factors 3 and 4.
Answer:

Explanation:
The commutative property states that the change in the order of numbers in an addition or multiplication operation does not change the sum or the product. The commutative property of addition is written as A + B = B + A. The commutative property of multiplication is written as A × B = B × A.
Suppose: 3 × 4 = 12.
4 × 3 = 12.
=> 3 × 4 = 4 × 3.

Lebraun makes 3 dogs and 2 birds. Does he use more craft sticks for the birds or for the dogs?
Answer:
He uses 3 more craft sticks for the birds than for the dogs.

Explanation:
Number of dogs Lebraun makes = 3.
Number of dog craft sticks = 5.
Number of craft stick dogs Lebraun makes = Number of dogs Lebraun makes × Number of dog craft sticks
= 3 × 5
= 2 × 5 + 5
= 10 + 5

Number of birds Lebraun makes = 2.
Number of birds craft sticks = 6.
Number of craft stick birds Lebraun makes = Number of birds Lebraun makes × Number of birds craft sticks
= 2 × 6
= 1 × 6 + 6
= 6 + 6
= 12.
Difference:
Number of craft stick dogs Lebraun makes – Number of craft stick birds Lebraun makes
= 15 – 12
= 3.

 

Question 7.
Ariel makes 2 cats and 2 dogs. How many more craft sticks does she need to make the cats?
Answer:
6 more craft sticks she needs to make the cats.

Explanation:

Number of dog craft sticks = 5.
Number of craft stick dogs Ariel makes = Number of dogs Ariel makes × Number of dog craft sticks
= 2 × 5
= 1 × 5 + 5
= 5 + 5
= 10.
Number of cats Ariel makes = 2.
Number of cats craft sticks = 8.
Number of craft stick cats Ariel makes = Number of cats Ariel makes × Number of cats craft sticks
= 2 × 8
= 1 × 8 + 8
= 8 + 8
= 16.
Difference:
Number of craft stick cats Ariel makes – Number of craft stick dogs Ariel makes
= 16 – 10
= 6.

Multi-Step Anders makes 7 fruit cups. He puts 2 green grapes, 2 red grapes, and 2 black grapes in each fruit cup. How many grapes does Anders use for the fruit cups?
(A) 42
(B) 28
(C) 13
(D) 14
Answer:
Number of grapes Anders uses for the fruit cups = 42.
(A) 42

Explanation:
Number of fruit cups Anders makes = 7.
Number of green grapes he puts = 2.
Number of red grapes he puts = 2.
Number of black grapes he puts = 2.
Number of grapes Anders uses for the fruit cups = Number of fruit cups Anders makes(Number of green grapes he puts + Number of red grapes he puts + Number of black grapes he puts)
= 7(2 + 2 + 2)
= 7(4 + 2)
= 7 × 6
= 42.

Question 13.
How many pails of food do the elephants eat in one week?

Answer:
Number of pails of food elephant eats in a week = 63.

Explanation:
Number of pails of food elephant eats in a day = 9.
Number of days in a week = 7.
Number of pails of food elephant eats in a week = Number of days in a week  × Number of pails of food elephant eats in a day
= 7 × 9
= 63.

Question 14.
If the zoo keepers increased the lion’s feed by 2 pails, how many pails of food would the lions eat in one week?
Answer:
Number of pails of food would lion eats in a week = 56.

Explanation:
Number of pails of food lion eats in a day = 4.
Number of days in a week = 7.
Number of pails of food lion eats in a week = Number of days in a week  × Number of pails of food lion eats in a day
= 7 × 4
= 28.
If the zoo keepers increased the lion’s feed by 2 pails.
=> Number of pails of food would lion eats in a week = 2 × Number of pails of food lion eats in a week
= 2 × 28
= 56.

Question 15.
How many more pails of food do the zebras eat in one week than the lions?
Answer:
21 more pails of food do the zebras eat in one week than the lions.

Explanation:
Number of pails of food lion eats in a week = 28.
Number of pails of food zebra eats in a day = 7.
Number of days in a week = 7.
Number of pails of food zebra eats in a week = Number of days in a week  × Number of pails of food zebra eats in a day
= 7 × 7
= 49.
Difference:
Number of pails of food zebra eats in a week – Number of pails of food lion eats in a week
= 49 – 28
= 21.

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?

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

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

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

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)

Answer:
The number of pictures are there in all = 16.

Explanation:
The number of pictures each drew = 4.
Two more students draw the same number of pictures.
=> Number of total people drew the pictures in all = 4.(Terry and Raul and 2 students)

(C) 5 + 5 + 5 + 5
(D) 2 × 10 = 20
Answer:
Total number of flowers Ty has = 40.
(B) 2 × 10 = 20 and 2 × 10 = 20 then 20 + 20 = 40.

Explanation:
Number of bunches of flowers Ty has = 4.
Number of flowers each bunch Ty has = 10.
Total number of flowers Ty has = Number of bunches of flowers Ty has × Number of flowers each bunch Ty has
= 4 × 10
= (2 × 10) + (2 × 10)

(A) 3
(B) 13
(C) 18

Answer:
Number of cans of paint Adam have now = 18.
(C) 18.

Explanation:
Number of boxes of paints Adam has = 5.
Number of cans of paint each box has = 6.
Number of boxes he uses = 2.
Number of cans of paint Adam have now = (Number of boxes of paints Adam has × Number of cans of paint each box has) – (Number of boxes he uses × Number of cans of paint each box has)
= (5 × 6) – (2 × 6)
= 30 – 12

In a multiplication sentence, the two numbers either side of the multiplication sign are called factors.
The number after the equals sign is called the multiple.
Explanation:
For example:
If you write the two smaller numbers the other way around as 5 × 3 = 15 instead of 3 × 5 =15,
this does not matter when talking about this array.
