• 4 + 4

• 4 + 4 + 4 + 4

On each of three days, Michael painted 7 pictures. How many pictures did Michael paint?

• 7

• 14

Which of the following is an example of the Commutative Property of Multiplication?

• 2 + 6 = 6 + 2

• 2 × (6 + 3) = (2 × 6) + (2 × 3)

• 6 × 2 = 2 × 6

• 6 × 1 = 6

Answer explanation

The Commutative Property of Multiplication states that changing the order of factors does not change the product. Thus, 6 × 2 = 2 × 6 is a correct example, while the other options illustrate different properties.

Royal arranges books into 2 equal rows with 4 books in each row. Draw an array to match how Royal arranges his books.

• 2 rows of 4 books

• 4 rows of 2 books

• 1 row of 8 books

• 8 rows of 1 book

Answer explanation

Alan arranges his books into 2 equal rows with 4 books in each row, which clearly matches the choice '2 rows of 4 books'. The other options do not reflect this arrangement.

How many books did Royal arrange in all?

• 6

• 8

• 10

• 12

Answer explanation

Alan arranged a total of 8 books, which is the correct answer. The other options (6, 10, 12) do not match the total number of books he arranged.

Which shows another way to write 3 + 3 + 3 + 3 + 3 + 3?

• 6 - 3

• 6 × 3

• 6 ÷ 4

• 6 + 3

Answer explanation

3 + 3 + 3 + 3 + 3 + 3 equals 6 groups of 3, which can be expressed as 6 × 3. The other options do not represent this sum correctly.

Write a repeated addition sentence to solve the problem 6 × 5.

• 5 + 5 + 5 + 5 + 5 + 5

• 6 + 6 + 6

• 5 + 5 + 5 + 5

• 6 + 6 + 6 + 6 + 6 + 6

Answer explanation

The problem 6 × 5 means adding 5 a total of 6 times. Therefore, the correct repeated addition sentence is 5 + 5 + 5 + 5 + 5 + 5, which represents 6 groups of 5.

Breontae has 5 packs of markers, each containing 4 markers. Which three have the same value as the total number of markers Breontae has?

• 4 + 4 + 4 + 4 + 4

• 4 + 4 + 4 + 4

• 5 + 5 + 5 + 5 + 5

• 4 × 5

• 20

Answer explanation

5 × 4 equals 20. The expression 4 + 4 + 4 + 4 + 4 sums to 20, and 4 × 5 also equals 20. Therefore, the correct choices are 4 + 4 + 4 + 4 + 4, 4 × 5, and 20.
