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 X 5 = 15,

Explanation:

Given expressions as

3 groups of five means 3 X 5 = 15,

3 fives = 3 x 5 = 15 and

3 X 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 X 3 = 15,

5 X 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 X 6 = 24,

Explanation:

Given expressions as

6 + 6 + 6 + 6 = 24 as 6 is added 4 times,

4 groups of six = 24 means 4 X 6 = 24,

4 X 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 x 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 X 4 we get 24, So 6 groups of 4 = 24,

6 X 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 X 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 X 3 = 6 whose value is not

same as shown in the picture ,

So, the picture does not show 2 X 3.

Question 3.

Draw a picture to show 2 × 3 = 6.

Explanation:

Drawn a picture above to show 2 X 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 X 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 X 4 = 12.

Fill in the blanks to make true repeated addition and

multiplication sentences that represent the picture.

True repeated addition is 2 + 2 + 2 + 2 = 8,

Multiplication sentences is 4 X 2 = 8.

Explanation:

Given the picture above shows 4 groups of

2 slices of watermelon.

Filled in the blanks to make true repeated addition

as 2 + 2 + 2 + 2 = 8 and multiplication sentences that

represent the picture as 4 X 2 = 8.

Question 2.

Draw a picture to show 3 + 3 + 3 = 9. Then,

write a multiplication sentence to represent the picture.

Addition sentence is 3 + 3 + 3 = 9,

Multiplication sentences is 3 X 3 = 9.

Explanation:

Drawn a picture above as 3 groups of 3 birds to show

3 + 3 + 3 = 9 and writing a multiplication sentence to

represent the picture as 3 X 3 = 9 birds in total.

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 X 5 = 20,

Explanation:

Given expressions as

4 groups of five means 4 X 5 = 20,

4 fives = 4 x 5 = 20 and

4 X 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 X 4 = 20,

Explanation:

Given expressions as

5 groups of four means 5 X 4 = 20,

5 fours = 5 x 4 = 20 and

5 X 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 x 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 X 6 we get 18, So 3 groups of 6 = 18,

3 X 6 = 18 as 3 is multiplied by 6 we get 18.

d. 3 + __3__ + __3__ + __3__ + __3__ + __3__ = ___18____

6 X 3 we get 18, So 6 groups of 3 = 18,

6 X 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 X 3,

Explanation:

Given the picture below shows 3 groups of of hot dogs,

In the 3 groups the number of hot dogs are the same as 3,
