Distributive Property 1
Complete the equation using the distributive property:
5 x 3 = (2 x 3) + (_ x 3)
5 x 3 = (2 x 3) + (3 x 3)
Complete the equation using the distributive property:
9 x 10 = (3 x 10) + (_ x 10)
9 x 10 = (3 x 10) + (6 x 10)

Ms. Katie buys apples from the store. She lays them out on her counter in 3 rows of 5.
Then, she buys oranges from the store. She adds them to the array in 4 rows of 5.
There are 7 rows of 5 fruit total.
Complete the equation below:
7 x 5 = (_ x 5) + (_ x 5)
7 x 5 = (3 x 5) + (4 x 5)
Ms. Katie organizes her Oreo cookies in 8 rows of 2.
Then, she adds chocolate bars to the array. She adds 2 rows of 2 chocolate bars.
There are 10 rows of 2 total.
Complete the equation below:
10 x 2 = (_ x 2) + (_ x 2)
10 x 2 = (8 x 2) + (2 x 2)
Which of the following is allowed when Ms. Katie is giving instructions or speaking to the class?
a) Chitchatting with neighbors
b) Commenting without raising your hand
c) Being distracted by playing with toys/pencils/objects
d) None of the above
d) None of the above
Ms. Katie has 2 rows of 8 pancakes. She adds 5 rows of 8 waffles.
Explain why the sentence below is true using the parts of the array:
7 x 8 = 16 + 40
7 x 8 = (2 x 8) + (5 x 8)
= 16 + 40
There are 2 rows of pancakes and 5 rows of waffles.
In total, there are 2 + 5 = 7 rows.
Multiplying 7 x 8 gets the total amount in the whole array. This is the same as solving the pancakes (2 x 8 = 16) and solving the waffles (5 x 8 = 40) and adding them together (16 + 40).
Ms. Katie has 7 rows of 4 plates. She adds 3 rows of 4 bowls.
Explain why the sentence below is true using the parts of the array:
10 x 4 = 28 + 12
10 x 4 = (7 x 4) + (3 x 4)
= 28 + 12
There are 7 rows of plates and 3 rows of bowls.
In total, there are 7 + 3 = 10 rows.
Multiplying 10 x 4 gets the total amount in the whole array. This is the same as solving the plates (7 x 4 = 28) and solving the bowls (3 x 4 = 12) and adding them together (28 + 12).
How should you be prepared by the start of class?
a) Snacks, toys, reading books, and all other items put away
b) Math books out
c) Eating snacks and playing with toys
d) Both (a) and (b)
d) Both (a) and (b)
Using the distributive property, find three ways to write the expression (7 x 6).
7 x 6 = (_ x 6) + (_ x 6)
= (_ x 6) + (_ x 6)
= (_ x 6) + (_ x 6)
7 x 6 = (1 x 6) + (6 x 6)
= (2 x 6) + (5 x 6)
= (3 x 6) + (4 x 6)
(The order does not matter!)
(Using the commutative property, you can switch the expressions around.)
Using the distributive property, find three ways to write the expression (8 x 2).
8 x 2 = (_ x 2) + (_ x 2)
= (_ x 2) + (_ x 2)
= (_ x 2) + (_ x 2)
Choose any three out of the following options:
8 x 2 = (1 x 2) + (7 x 2)
= (2 x 2) + (6 x 2)
= (3 x 2) + (5 x 2)
= (4 x 2) + (4 x 2)
(Using the commutative property, you can switch the expressions around.)

a) Completing all assigned work during class and correcting your work
b) Following classroom etiquette
c) Running and screaming
d) Both (a) and (b)
d) Both (a) and (b)
