Could the students use 24 paper squares to make quilts with 5 rows of
paper squares? How do you know? Use an array to help explain your
answer.
No, the students cannot use 24 paper squares to make quilts with 5 rows of paper squares.
To explain why, we can use an array.
If we have 24 paper squares, and we want to arrange them in 5 rows, each row will need to have an equal number of squares. Using an array, we can create 5 rows with an equal number of squares in each row.

In this array, we have 5 rows, but we only have a total of 21 squares. To have 5 rows, each row needs to have the same number of squares. Since we have 24 squares, which is not divisible by 5, the students cannot use 24 paper squares to make quilts with 5 rows of paper squares.
