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 × 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 × 6 = 18 markers.
