Marlon picked plums off a tree in the yard.  He gave

42 plums to a neighbor and had 43 left.  Which

equation, when solved, will tell how many plums

Marlon picked?

 42 ÷ p = 43

 p - 42 = 43

 42 - 43 = p

 42 ÷ 43 = p

Joanna bought some toy cars at a garage sale.  She

gave 51 cars to her sister and had 14 cars left.

Which equation, when solved, will tell how many

cars Joanna bought at the garage sale?

 65 - 51 = c

 14 - c = 51

 51 ÷ 14 = c

Patrick owns 2 marbles.  When Patrick and Danielle

put all of their marbles together, they have 902

marbles.  Which equation, when solved, will show

how many marbles Danielle owns?

 2 - 902 = m

 2 - m = 902

 2 + m = 902 

 2  x m = 902

Raymond bought some stamps.  He used 34 of the

stamps and had 275 stamps left.  Which equation,

when solved, will show how many stamps he

bought?

 s ÷ 34 = 275

 s - 34 = 275

 275 + s = 34

Jackson bought 74 packages of light bulbs.  He

bought 592 light bulbs in all.  Which equation,

when solved, will tell how many light bulbs were

in each package?

 592 x b = 74

 b + 74 = 592

 74 ÷ b = 592

Damon bought some buttons at the craft store. He

used 4 of them for an art project and had 79 left.

Which equation, when solved, will tell how many

buttons Damon bought?

 b - 4 = 79

 79 - b = 4

 83 - 4 = b

After a field trip to the aquarium, Ariel decided to

collect fish stickers.  She started off with 27 fish

stickers.  Then she bought some more fish stickers

at the store.  Now Ariel has 70 fish stickers in all.

Which equation, when solved, will show how many

 27 + s = 70

 70 + s = 27

 27 ÷ s = 70

 27 - s = 70

Aaron bought 15 packages of toy cars.  He bought

45 toy cars in all.  Which equation, when solved,

will tell how many toy cars were in each package?

 15 ÷ b = 45

 b + 15 = 45

 45 x 15 = b

 15 x b = 45

A group of tourists divided themselves among 5

boats for a river tour.  There were 6 tourists on

each boat.  Which equation, when solved, will tell

 5 ÷ 6 = t

 t x 5 = 6

 t - 5 = 6

 t ÷ 5 = 6

The school is going to use 10 boxes to ship some

books to another school.  The school needs to ship

450 books.  Which equation, when solved, will tell
