Match the word problem with the expression:
During the Easter Egg Hunt, I found some eggs.  On the way to the car, I found 15 more.

• 1x + 15

• x + 15

• 15 - x

• 15 = x + 10

Match the word problem with the expression:
A teacher had 16 students.  She needed to split up her class into a number of equal groups.  When she was finished, she had 4 groups.

• f x 4 = 16

• 16 x 4 = f

• f = 16 ÷ 4

• 16 ÷ f = 4

Match the word problem with the expression or equation: Mrs. Swilley needed to give 9 boxes of supplies to some groups equally.

• 9 ÷ h = 1

• 9 ÷ h

• 1 x h = 9

• h ÷ 9

Match the word problem with the expression:
Mrs. Swilley's class had 15 students.  Each student did an equal number of word problems.  When finished, together the class completed 45 word problems.

• 15y = 45

• 45 ÷ 15 = y

• 45 ÷ y = 15

• 45 - y = 15

Match the word problem with the expression:
There are 14 rows with a number of chairs in each row in the cafeteria.  There are also 6 chairs against the wall.

• 6 ⋅ 14x

• 14 + 6x

• 14x + 6

• x = 6 + 14
