Question 1.
Fill in the blanks to make true statements.

a. 3 groups of five = ___15______
3 fives = ____15_____
3 × 5 = ___15______

3 groups of five = 15,
3 fives = 15,
3 × 5 = 15,

Explanation:
Given expressions as
3 groups of five means 3 × 5 = 15,
3 fives = 3 × 5 = 15 and
3 × 5 = 15 as 3 is multiplied by 5 we get 15.

b. 3 + 3 + 3 + 3 + 3 = __15___
5 groups of three = ___15______
5 × 3 = ____15_____

3 + 3 + 3 + 3 + 3 = 15,
5 groups of three = 15,
5 × 3 = 15,

Explanation:
Given expressions as
3 + 3 + 3 + 3 + 3 = 15 as 3 is added 5 times,
5 groups of three = 15 means 5  × 3 = 15,
5 × 3 = 15 as 5 is multiplied by 3 we get 15.

c. 6 + 6 + 6 + 6 = ___24________
____4___ groups of six = ___24_______
4 × __6____ = ____24______

6 + 6 + 6 + 6 = 24,
4 groups of six = 24,
4 × 6 = 24,

Explanation:
Given expressions as
6 + 6 + 6 + 6 = 24 as 6 is added 4 times,
4 groups of six = 24 means 4  × 6 = 24,
4 × 6 = 24 as 4 is multiplied by 6 we get 24.

d. 4 +__4__ + __4__ + __4__ + _4___ + __4__ = ___24______
6 groups of ____4____ = ____24_______
6 × __4____ = ____24______

4 + 4 + 4 + 4 + 4 + 4 = 24,
6 groups of 4 = 24,
6 × 4 = 24,

Explanation:
Given expressions as
4 + ___ + ___ +___ +___ +___ =  means by seeing the picture
4 is added 6 times as 4 + 4 + 4 + 4 + 4 + 4 we get 24,
6 groups of ______ =  means again by seeing the picture
6 × 4 we get 24, So 6 groups of 4 = 24,
6 × 4 = 24 as 6 is multiplied by 4 we get 24.

Question 2.
The picture below shows 2 groups of apples. Does the picture show 2 × 3? Explain why or why not.

No, the picture does not show 2 × 3,

Explanation:
Given the picture below shows 2 groups of apples but in the 2 groups the number of apples are not the same as in group -1 we have 3 apples, group 2 we have 2 apples in total there are 5 apples and 2 × 3 = 6 whose value is not same as shown in the picture.
So, the picture does not show 2 × 3.

Question 3.
Draw a picture to show 2 × 3 = 6.

Explanation:
Drawn a picture above to show 2 × 3 = 6 .

Question 4.
Caroline, Brian, and Marta share a box of chocolates. They each get the same amount. Circle the chocolates below to show 3 groups of 4. Then, write a repeated addition sentence and a multiplication sentence to represent the picture.

Addition sentence is 4 + 4 + 4 = 12,
Multiplication sentence is 3 × 4 = 12,

Explanation:
Given Caroline, Brian, and Marta share a box of chocolates and they each get the same amount as 12 ÷ 3 = 4 each.
Circled the chocolates above to show 3 groups of 4 and wrote a repeated addition sentence as  4 + 4 + 4 = 12 and a multiplication sentence to represent the picture as 3 × 4 = 12.

Question 1.
Fill in the blanks to make true statements.

a. 4 groups of five = ____20_____
4 fives = ___20______
4 × 5 = ____20_____

4 groups of five = 20,
4 fives = 20,
4 × 5 = 20,

Explanation:
Given expressions as
4 groups of five means 4 × 5 = 20,
4 fives = 4 × 5 = 20 and
4 × 5 = 20 as 4 is multiplied by 5 we get 20.

b. 5 groups of four = _________
5 fours = _________
5 × 4 = _________

5 groups of four = 20,
5 fours = 20,
5 × 4 = 20,

Explanation:
Given expressions as
5 groups of four means 5 × 4 = 20,
5 fours = 5 x 4 = 20 and
5 × 4 = 20 as 5 is multiplied by 4 we get 20.

c. 6 + 6 + 6 = ___18________
____3___ groups of six = ____18______
3 × __6____ = ____18______

6 + 6 + 6  = 18,
3 groups of 6 = 18,
3 × 6 = 18,

Explanation:
Given expressions as 6 + 6 + 6 = 18 as
6 is added 3 times we get 18,
_____ groups of six =  means again by seeing the picture
3 groups of 6 =  3 × 6 we get 18, So 3 groups of 6 = 18,
3 × 6 = 18 as 3 is multiplied by 6 we get 18.

Explanation:
Given expressions as
3 + ___ + ___ +___ +___ +___ =  means by seeing the picture
3 is added 6 times as 3 + 3 + 3 + 3 + 3 + 3 we get 18,
6 groups of ______ =  means again by seeing the picture
6 × 3 we get 18, So 6 groups of 3 = 18,
6 × 3 = 18 as 6 is multiplied by 3 we get 18.

Question 2.
The picture below shows 3 groups of hot dogs. Does the picture show 3 × 3? Explain why or why not.

Yes, the picture shows 3 × 3,

Explanation:
Given the picture below shows 3 groups of hot dogs,
In the 3 groups the number of hot dogs are the same as 3, So in total we have 3 X 3 = 9 hotdogs in the picture which matches with the given equation as 3 × 3 whose value is also same 9, So, the picture shows 3 × 3.
