Mr. Williams is making wooden toy trucks for a craft show. He has two boxes of wood for the trucks. One box contains 25 pieces of wood and the other contains 50 pieces of wood.
Each truck requires 6 pieces of wood.
How many toy trucks can Mr. Williams make?
25 ÷ 6 = 4 r 1
50 ÷ 6 = 8 r 2
8 + 4 = 12
12 toy trucks

Which statements about remainders and the number of trucks Mr. Williams can make are true?
A. Since 25 ÷ 6 has a remainder of 1, and 50 ÷ 6 has a remainder of 2, Mr. Williams can make an additional truck.
B. If the total of the remainders is less than 6, Mr. Williams cannot make an additional truck. So the remainders can be ignored.
C. Since 25 ÷ 6 has a remainder of 1, and 50 ÷ 6 has a remainder of 2, Mr. Williams cannot make another truck. The remainders can be ignored.
D. Mr. Williams can add the pieces from the two boxes together first before determining whether he can ignore the remainders or not.
E. If there are any number of remainders, Mr. Williams can make another truck.
B. If the total of the remainders is less than 6, Mr. Williams cannot make an additional truck. So the remainders can be ignored.
C. Since 25 ÷ 6 has a remainder of 1, and 50 ÷ 6 has a remainder of 2, Mr. Williams cannot make another truck. The remainders can be ignored.

Mr. Bollis has 2 pieces of fabric to make costumes. One piece is 11 yards long and the other is 15 yards long. Each costume requires 3 yards of fabric.
How many costumes can Mr. Bollis make? How do the remainders affect the number of costumes he can make?
11 ÷ 3 = 3 r2
15 ÷ 3 = 5
3 + 5 = 8
8 costumes with 2 yards left over. 2 yards is too short for another costume so the remainder can be ignored.

The pizza stand gives customers a free pizza when they collect 8 coupons. How many free pizzas can Mrs. Fowler get if she has 78 coupons?
How does the remainder affect the number of free pizzas she gets?
How many more coupons does she need for the next free pizza? Why?
She can get 9 free pizzas.
The remainder of 6 can be ignored since she does not have enough for another free pizza.
She needs 2 more coupons because 6 + 2 = 8.
