Miss Rosner made 48 cookies for Alyssa’s birthday. She put an equal number of

cookies in 8 plastic bins so Alyssa could carry them to school. Write an equation that could be used to find out how many

cupcakes are in each bin.

Question #1

48 ÷ 8 = c

(or you can use any variable in place of

“c”)

Miss Rosner, Ms. Cole, Mrs. Flett, and Mrs. Boundy are planning a field trip to the zoo.

They are planning on reserving buses to take all 94 students and 4 teachers. There will be

7 buses. If we put an equal amount of people on each bus, how many people can fit

on each bus?

Question #2.

94 Students + 4 Teachers= 98 Total People

98 people ÷ 7 buses = 14 People on Each Bus

Answer: 14 People on Each Bus

Alyson earned $162 by waiting on tables at TGI

Friday’s for 5 hours. Write a number sentence that shows the best way to

estimate how much she earned each hour.

Question #3

$160 ÷ 5 = m (or you can use any variable in

place of “M”)

OR

$160 ÷ 5 = $30You must have the $ sign in your equation

Alexandria and Nick went with their cousins to Dave and Buster’s and won 289

tokens playing games. They also had 113 tokens

with them from the last time they were there.

They want to turn all of the tokens in for candy prizes. If each candy

prize requires 8 tokens, how many pieces of candy can they get?

Question #4

289 tokens + 113 tokens = 402 total tokens

402 tokens ÷ 8 tokens per candy prize = 50 R2

These 2 remaining tokens are not enough for another piece of candy….. Therefore, they will need to save them for the

next time they go to Dave and Busters.

Answer: 50 candy prizes

USA Olympian, Michael Phelps, swims 2824 laps in 4 weeks . He swims an equal amount of laps each week. How many

laps will he have swam after 9 weeks?

Question #5

2824 laps ÷ 4 weeks = 706 laps per week

706 laps per week x 9 weeks = 6354 total laps

Answer: 6354 laps

Mrs. Nagy is planting 5 new flower gardens. She would like to have a brick border around each flower garden. She only has a total of 92 bricks. If each border requires 18 bricks, will Mrs. Nagy have enough to put a border around each flower garden? Will there be any left in case she wants to make another flower garden?.

Question #6

92 bricks ÷ 5 gardens = 18 R2 bricks per garden

OR

18 x 5 = 90.

Only 90 bricks are needed for the 5 flower gardens. Since there are a total of 92 bricks, there are 2 extra.

Answer: Yes. Mrs. Nagy has enough bricks for 5 flower gardens

She will have 2 bricks left.

Miss Rosner does odd jobs each month to earn extra money. This month, she earned $68 selling Thirty –One bags, $94 tutoring students, and $136 cleaning her neighbor’s house. Each month she puts half of the money she earns into the bank toward her girls’ college education. How much

money did she save this month?

Question #7

$68 selling Thirty- One

+ $94 tutoring $136 cleaning neighbor’s house

Answer: Miss Rosner saved $149 this month.

$298

Half means you need to divide by 2$298 ÷ 2 = $149

Tyler has 13 baseball, 9 football, and 8 hockey cards. He displays his

sports’ cards equally on 2 pages in an album. Write an equation to show how he found the number of cards to put

on each page.

Question #8

30 ÷ 2 = C

(or you can use any variable in place of

“C”)

Mrs. Rosenberg baked 45 brownies and 3 times as many cookies for her son Blake’s

wrestling party. She wanted to place them on plates. If each plate holds 8 items, how many plates will she need to hold all of the goodies

she baked?

Question #9

45 brownies x 3 (3 times as many brownies) = 135 cookies

45 brownies + 135 cookies = 180 goodies

Answer: 23 plates

180 goodies ÷ 8 items per plate = 22 R4 items

A case of school supplies holds 263

pencils, 300 highlighters, and 415

pairs of scissors. William Street School

bought 7 cases of supplies. Write an

equation that could be used to figure out how

many pencils the school bought. Then solve the equation.

Question #10

263 x 7 = p(or you can use any variable in

place of “p”)

Equation solved:

263 x 7 = 1841 pencils

Ms. Cole is buying chicken wings for her class of 24 students. She figures each student will have 8

wings. How many boxes of wings should Ms. Cole buy if they come

in boxes of 9?

Question #11

24 students x 8 wings each = 192 wings needed.

192 wings ÷ 9 per package = 21 R3 .

21 boxes are not enough. 3 kids will only get 7 wings. Therefore, Ms. Cole needs to buy 22 boxes. She will have 6

wings extra from the 22nd box.

Answer: 22 boxes

Emily is saving money to buy an I-phone that costs $299. In the last

6 weeks, she has earned $54.

a.) Write an equation that you could use to determine how much money, m, she earns per week.

Then solve your answer.

b.) How many more weeks does Emily have to work to have enough money to buy the I-

phone?

Question #15

a.) $54 ÷ 6 = m

$54 ÷ 6 = $9 per week

b.) $299 - $54 = $245 left to save

$245 ÷ $9 = 27 R2After 27 weeks, Emily will only have saved $243. She needs an additional week in order to get the remaining $2 she needs

Answer: 28 Weeks

Tim Horton’s sells an average of 570 cups of coffee a day. The

manager wants to be sure he has enough carry-out containers on hand. Each carry-out container

holds 4 cups of coffee. If the manager expects half of all the

coffee sold to be put in carry-out containers, how many will he

need for that day?

Question #16

570 cups sold ÷ 2 (half) = 285 cups to go into carry out containers

570 ÷ 2 = 285

285 ÷ 4 cups per container = 71 R 1

71 containers are not enough. 1 cup of coffee will not have a carry-out container. Therefore, the manager needs to have

72 carry out containers on hand. There will be 3 extra spaces in the 72nd container.

Answer: 72 carry out containers

The cafeteria ordered 2,000 freezie pops for the school picnic. The freezie pops were shipped in

cardboard boxes that held 7 freezies. Any freezies left after the cardboard boxes were packed, were sent in an insulated bag. How many freezies were shipped in an insulated

bag?

Question #17

2000 freezies ÷ 7 per box = 285 R5

285 boxes of freezies were shipped. The remaining 5 were sent in an insulated bag.

Answer: 5 sent in an insulated bag
