What are two different ways to find the total number of squares in this partitioned rectangle?

• By counting each square individually and by multiplying the number of rows by the number of columns.

• By adding the number of squares in each row and by subtracting the number of empty spaces from the total area.

• By multiplying the length and width and by dividing the total area by the area of one square.

• By counting the number of rectangles and by multiplying the number of columns by the number of rows.

Alek makes an array with jars of paint. He puts 4 jars in each row. He has 2 rows of jars. Which equations can be used to find how many jars of paint are in Alek’s array? Choose all the correct answers.

• 4 + 4 = ?

• 2 + 2 + 2 + 2 = ?

• 4 + 4 + 2 = ?

• 4 + 4 + 4 + 4 = ?

• 2 + 2 = ?

Write two addition equations you could use to find the total number of circles in the array.

• 4 + 4 + 4 = 12 and 3 + 3 + 3 + 3 = 12

• 2 + 2 + 2 = 6 and 6 + 6 = 12

• 5 + 5 = 10 and 2 + 2 = 4

• 3 + 4 + 5 = 12 and 2 + 2 + 2 + 2 + 2 + 2 = 12

The two squares below are the same size. Each square is divided into equal parts in a different way. Are the shaded parts equal in size? Explain your answer.

• Yes, the shaded parts are equal in size because each square is divided into 4 equal parts and one part is shaded in each.

• No, the shaded parts are not equal in size because the shapes of the shaded parts are different.

• No, the shaded parts are not equal in size because one square is divided into more parts than the other.

• Yes, the shaded parts are equal in size because both squares have the same number of shaded parts.
