a. One row of an array is drawn below. Complete the array with Xâ€™s to make 4 rows of 5. Draw horizontal lines to separate the rows.

X X X X X

Answer:

4 rows of 5 X’s.

Explanation:

Here, we have constructed an array of 4 rows of 5 X’s and separated the rows with horizontal lines.

b. Draw an array with Xâ€™s that has 4 columns of 5. Draw vertical lines to separate the columns. Fill in the blanks.

____ + ____ + ____ + ____= ____

4 rows of 5 = _____

6 columns of 5 = _____

Answer:

4 columns of 5 X’s and the additional equation will be 5 + 5 + 5 + 5 = 20.

Explanation:

Here, we have constructed an array of 4 columns of 5 X’s and separated the rows with vertical lines and the addition equation will be 5 + 5 + 5 + 5 which is 20 and 6 columns of 5 X’s will be 30.

Question 2.

a. Draw an array of Xâ€™s with 3 columns of 4.

Answer:

3 columns of 4 X’s.

Explanation:

Here, we have constructed an array of 3 columns of 4 X’s

b. Draw an array of Xâ€™s with 3 rows of 4. Fill in the blanks below.

____ + ____ + ____ = ____

3 columns of 4 = _____

3 rows of 4 = _____

Answer:

3 rows of 4 X’s which will be 12 and the additional equation will be 4 + 4 + 4 = 12.

Explanation:

Here, we have constructed an array of 3 columns of 4 X’s and separated the rows with vertical lines and the addition equation will be 4 + 4 + 4 which is 12 and 3 columns of 4 X’s will be 12.

In the following problems, separate the rows or columns with horizontal or vertical lines.

Question 3.

Draw an array of Xâ€™s with 3 rows of 3.

____ + ____ + ____ = ____

3 rows of 3 = ____

Answer:

3 rows of 3 X’s which will be 9 and the additional equation will be 3 + 3 + 3 = 9.

Explanation:

Here, we have constructed an array of 3 rows of 3 X’s and separated the rows with horizontal lines and the addition equation will be 3 + 3 + 3 which is 9 and 3 rows of 3 X’s will be 9.

Question 4.

Draw an array of Xâ€™s with 2 more rows of 3 than the array in Problem 3. Write a repeated addition equation to find the total number of Xâ€™s.

Answer:

5 rows of 3 X’s and the addition equation will be 3 + 3 + 3 + 3 + 3= 15.

Explanation:

As there are 3 rows of 3 X’s and we need to add 2 more rows which will be 5 rows of 3 X’s and the addition equation will be 3 + 3 + 3 + 3 + 3= 15.

Question 5.

Draw an array of Xâ€™s with 1 less column than the array in Problem 4. Write a repeated addition equation to find the total number of Xâ€™s.

Answer:

2 columns of 5 X’s and the addition equation will be 5 + 5= 10.

Explanation:

As there are 3 columns of 5 X’s and we need to less 1 more column, then there will be 2 columns of 5 X’s and the addition equation will be 5 + 5= 10.
