Arent we going to the carnival today? These words wake you from a deep sleep. Every year, you wait for the carnival. You think about the fun rides. You dream about the special food. And dont forget the magic show and petting zoo! It seems as though this day has taken forever to arrive, and now its finally here! You jump out of bed and look at the clock. It is already 10 : 15 a. m. It will take you 15 minutes to eat, 5 minutes to get dressed, and 2 minutes to brush your teeth. What time will you be ready to go to the carnival? candy apples66page0006page0006.xhtml77page0007page0007.xhtml88page0008page0008.xhtmlIts now 10 : 37 a.m. You are almost out the door when youre reminded of your chores. Your dog, Zeus, wont get walked if you dont do it. So, you grab the leash and take him outside. When you get back, its 11 : 10 a.m. Now, wheres that carnival ticket? The search begins in your messy room. Is it under the bed or in your drawers? After 12 minutes of searching, you find it in your pocket. Your family could walk to the carnival, but that would take 45 minutes. And it might make you tired. Luckily, the bus comes by every 15 minutes. You get to the bus stop at 11 : 30 a. m. The next bus comes by in 10 minutes. So, you wait for it. The ride takes 25 minutes. What time do you get to the carnival? Lets99page0009page0009.xhtmlTime for Fun! Finally, you arrive at the carnival with your family. You see the bumper cars and the carousel nearby. Each ride lasts five minutes. Which one will you ride first? The line for the bumper cars is long, but it's your favorite ride. You like how the cars bump against one another and get trapped in the corner. The sign says it will be a 30-minute wait. But no one is in line for the carousel. You decide to start with the carousel and then get in line to wait for the bumper cars. How many minutes does it take for you to ride both rides?1010page0010page0010.xhtml1111page0011page0011.xhtmllog flume1212page0012page0012.xhtmlFinding Funnel Cakes The log flume is so close. After a brisk 5-minute walk, you decide to take a ride to cool off. At the top of the log flume's highest hill, you get a bird's-eye view of the carnival. You can see the Ferris wheel in the distance. After 12 minutes of watery fun, you decide to ride it next. But as you walk to the Ferris wheel, the smell of funnel cake fills the air. It gets stronger during your 8-minute walk. Your stomach grumbles. Instead of following the crowd to the Ferris wheel, you follow your nose to the food stand that is close by. For 5 sweet minutes, you enjoy every bite. How many minutes does it take you to get soaked, walk, and eat your snack? strawberry funnel cake1313page0013page0013.xhtmlAt the Magic Show Its 1 : 15 p. m. With a stomach full of funnel cake, going on a ride that spins in circles might not be the best idea. You dont want to feel sick at the carnival. That would ruin your whole day! What activity might let you rest for a bit, but still have fun? You see that a magic show will begin at 1 : 30 p. m. The theater is right around the corner. Luckily, a seat in the front row is waiting for you. The show begins four minutes late, but it is worth the wait. The magician pulls a rabbit out of an empty hat. He saws his assistant into two pieces. Then, he pulls a goldfish out of someones ear. Finally, he crawls into a box and disappears. All of this takes 30 minutes. By the time it is over, your stomach feels fine. Now, back to those rides!1414page0014page0014.xhtml1515page0015page0015.xhtmlThe Fabulous Ferris Wheel Your watch says 2 : 04 p.m. The Ferris wheel pauses to load new people. You wait in line for five minutes and step on board. There are not many riders. It only takes another six minutes for the rest of the people to board. As you wait, you read a sign. It has information about the very first Ferris wheel. People rode the first Ferris wheel in 1893. One turn around took 20 minutes! Finally, the wait is over, and the Ferris wheel goes round and round. From the top, you can see the entire carnival. After just nine minutes, your ride is over. It is your turn to step off the Ferris wheel. That was so much fun! The first Ferris wheel debuted at the 1893 Chicago World's Fair.1616page0016page0016.xhtmlLets1717page0017page0017.xhtmlWaiting Instead of Riding By the time you walk to the next ride, it is 2 : 30 p. m. The line for the pendulum ride winds around it twice! You have a bit of a wait ahead of you, but you know it will be worth it. From the ground, the pendulum swings from one side to the other. You feel a tickle in your stomach as you watch it swing. Happy riders scream with excitement. This is going to be fun! After 10 minutes, you get closer to the front of the line. When you finally get there, the worker puts up a sign Closed for maintenance. You don't want to give up your place in line, so you wait. Much to your dismay, the ride takes 45 minutes to reopen, but at least you get your turn.1818page0018page0018.xhtmlLets1919page0019page0019.xhtml2020page0020page0020.xhtmlExtending the Fun Your watch tells you that it is 3 : 25 p.m. You walk to the games area and see the basketball hoops. You also see people trying to toss small balls into fishbowls. And then there's the ringtoss game. Which one should you play? Tossing rings looks like fun, but you really want to win the prize at the basketball game. It turns out the choice isn't as tough as you thought. The basketball game only takes 2 minutes. You walk away a winner! But, the stuffed animal is way too big to carry. So you look for a locker to keep it safe. After 30 minutes, you find a locker. You put the stuffed animal inside. What time is it now?2121page0021page0021.xhtmlDinnertime At 4 : 00 p.m., you arrive at the food stands. You need a meal to eat, not just a snack. One stand is selling corn dogs. Another stand has roasted turkey legs. You also see hamburgers and fries. What do you want to eat? It will take 2 minutes to get a corn dog. The turkey leg stand has a 10-minute wait. The wait for a hamburger and fries is 5 minutes. You know that you want to spend as much time as you can at the petting zoo before it closes. So, you check a map and see that it will take you 5 minutes to walk there. The map also tells you that the petting zoo closes at 4 : 30 p. m. You have a big decision to make.2222page0022page0022.xhtmllets Food Wait TimeTime It Takes to Eat corn dog 2 minutes 8 minutes turkey leg 10 minutes 8 minutes hamburger and fries 5 minutes 8 minutes2323page0023page0023.xhtml2424page0024page0024.xhtmlAt the Petting Zoo You eat dinner and make it to the petting zoo before it closes. The baby chicks are fuzzy and cute. They are easy to pick up and hold. But the baby pigs are another story. You run around trying to catch one, but they are too quick. After five minutes, you give up. The miniature horses look calm. So, you decide to buy some carrots to feed them. It takes them nine minutes to eat the carrots. Before you know it, the workers tell you the petting zoo is closed. You did not get to pet all the animals, but you still had fun.2525page0025page0025.xhtmlPin Performance You want to squeeze in one more ride before your family meets to head home. But, you see a man juggling pins. You stop to watch him. He spins around and continues to catch the pins quite easily. A crowd forms around him, and everyone wants to see what he will do next. The man points at you and wants you to join him juggling the pins in midair. You've never done this before, but it looks easy, so you say yes! On the very first toss, you catch the pin and throw it right back to him. This goes on for several minutes, and the crowd claps when it ends. You look at your watch and see that 30 minutes have passed.2626page0026page0026.xhtml2727page0027page0027.xhtmlA Day of Good Times Before you know it, it's 5 : 00 p.m. The next bus arrives in 30 minutes. The swing around ride is near the front gate of the carnival. So, you decide to ride it before heading back to the bus stop. The wait and the ride only take 15 minutes. Then, you go to the locker to get your stuffed animal. You make your way out of the carnival and to the bus stop. That takes another 12 minutes. You think about all the fun you had during the day as you get on the bus with your family. What was the best part of the day? Was it the food, the show, the rides, the petting zoo, or the games? You can't decide because you liked it all and can't wait to come back next year!2828page0028page0028.xhtmlLets2929page0029page0029.xhtmlProblem Solving It's the end of the day and almost time to go home from the carnival.
