b. Compare the drawing to your array. How are they the same? How are they different?

a.

Shown triangles as an array that shows 3 rows of four.

Explanation:

Given the triangles as 3 groups of four.

a. Redrawn the triangles as an array that

shows 3 rows of four as shown in the picture above.

b. Same : Both have same number of triangles,

Different : Drawing is not in any order but my array

has an order of 3 rows of 4.

Question 6.

Roger has a collection of stamps.

He arranges the stamps into 5 rows of four.

Draw an array to represent Roger’s stamps.

Then, write a multiplication equation to

describe the array.

Drawn an array to represent Roger’s stamps.

Multiplication equation to describe the array is 5 X 4 = 20 stamps,

Explanation:

Given Roger has a collection of stamps.

He arranges the stamps into 5 rows of four.

Drawn an array to represent Roger’s stamps

as shown above then wrote a multiplication equation

to describe the array as 5 X 4 = 20 stamps.

Question 7.

Kimberly arranges her 18 markers as an array.

Draw an array that Kimberly might make.

Then, write a multiplication equation to describe your array.

Drawn an array that Kimberly might make,

Multiplication equation to describe the array is 3 X 6 = 18,

Explanation:

Given Kimberly arranges her 18 markers as an array,

may be of 3 rows of 6 markers each, Drawn an array

that Kimberly might make as shown in the picture above,

Then, wrote a multiplication equation to describe

my array as 3 X 6 = 18 markers.
