They are always a lot of fun! When her friends have birthday parties, she cant wait to go. She looks forward to the games and the food. But, her favorite part is talking with her friends about the terrific party they just attended! Malika wants to be sure that her party gives everyone plenty to talk about. Malikas party is just two weeks away. So, she is giving it a lot of thought. She wants to include all of her friends. There have to be decorations. Games are important, too. Tasty food is a must! Malika realizes this birthday party will take effort. She has to plan it all out, and there is no time to lose. She wants her party to be special because her friends are special. After all, a birthday party only happens once a year. She wants everyone to remember hers.66page0006page0006.xhtml77page0007page0007.xhtmlDetails and Decisions Its time to get to work! Planning a party takes time and thought. There are many details to consider. Malika is ready, though. She has some great ideas for putting together a wonderful birthday party for herself and her friends. There are a lot of decisions to make. First, she needs to decide what decorations there should be. Then, she needs to figure out how many of the decorations she will need. Guest lists help party planners make sure everyone has been invited.88page0008page0008.xhtmlNext, she needs to decide how many people to invite. This part is important. She wants to have all of her friends come to her party. When she knows how many people will be there, she can start planning the food. What would a birthday party be without food? It would be a lot of hungry people! Last, she needs to think about party favors. It is fun to leave a birthday with a little present. She wants her guests to feel special, too. Calendars and checklists help people track time and tasks when planning big events.99page0009page0009.xhtmlThis party store sells latex and mylar balloons.1010page0010page0010.xhtmlDecorations Malika wants her party to be bright and exciting. She thinks back to her friend Jins birthday party. There were balloons everywhere she looked. It was very pretty. She decides she wants her party to look like that, too. At the party store, Malika finds the balloon aisle. But there are so many! They are different sizes and colors. There are balloons made of latex, which is like rubber. There are balloons made of mylar, which is like foil. Malika has some hard decisions to make. Malika likes the plain latex balloons the best. But she cant decide which color to get. She thinks about it for a long time. Finally, she picks the yellow and blue balloons. Those are her favorite colors. She plans to tie them in groups around her house.1111page0011page0011.xhtmlMalika thinks the colors will look great. But she does not know how many balloons to buy. She wants them to be equally divided among the 5 tables at her party. She sees a bag of 15 balloons. Since there are 5 tables, that means there will be 3 balloons at each table. That seems nice, but Malika wants something special! Maybe there should be 5 balloons on each table. This means she needs more than 15. So, she multiplies. She knows that she has 5 tables. Now, she knows the number of balloons she wants at each.1212page0012page0012.xhtmlPlacing 5 balloons on each of the 5 tables means there will be 25 balloons. Malika sees a package of 10 blue balloons. Next to it is a bag with 10 yellow balloons. Finally, she sees a package of 5 sparkly silver balloons. This is perfect! She has the right number of balloons for her party. Let's1313page0013page0013.xhtmlThis cake could not feed 400 people.1414page0014page0014.xhtmlInvitations Now it is time to start thinking about guests. Malika needs to send invitations. But first, she must decide how many people to invite. She gives the guest list a lot of thought. She needs to plan well. She wants to invite all of her friends, but she cant invite everyone she knows. She imagines a party with everyone from her school. That would be 400 people! A party that big would be crazy. There wouldnt be enough room for everyone. Her house certainly wouldnt have enough chairs. She would also have to buy a lot of food and cake. Buying that much food would be expensive; much more expensive than what her current budget allows. And theres no way that 400 guests could share the food that she could afford to buy. Who would enjoy a sliver of cake or a pinch of party mix?1515page0015page0015.xhtmlNext, Malika imagines a party with just her family. Family parties can be fun. She had one last year. At that party, they all ate food and sang. But they didnt really play any games. Malika decides to share a fun celebration with her friends. Malika thinks about her options. Now, she has to make a decision. She knows she cant invite her whole school. She also knows she wants to invite more than just family members. Her class has 20 students. That number sounds about right. She has enough money in her budget to buy food for 20 people. And, since she can invite everyone in her class, no one will feel left out. Malika decides this is the perfect plan.1616page0016page0016.xhtmlLet's1717page0017page0017.xhtmlFood Malika is almost done planning her party. She has invited students from her class. She has picked decorations. Now, it is time to think about food. But, food is tricky. People like different things. Malika doesnt have to think about this long. Her favorite food is pizza, and thats what she wants to serve. How much pizza should she order? Malika has to decide. But shes not worried. She knows how many people are coming, so this will be easy. There are two ways Malika can plan. She can order a lot of pizza and divide it among the 20 people. She can also guess how many slices of pizza each person will eat and multiply that by 20. Both ways will work. Malika decides she needs 40 slices of pizza. If she divides those slices among the 20 people at the party, each person will have 2 slices. That seems right to Malika. She can now cross one more item off her list!1818page0018page0018.xhtmlLet's1919page0019page0019.xhtmlOn the Side? Pizza isnt the only food Malika needs to buy. After her friends birthday party, everyone was talking about the vegetable trays. She knows her guests want to eat more than just pizza. But, she doesnt want to have the same food as the last party. Malika thinks a crisp, cool side dish would be best. She decides to serve fruit salad. How many cups of fruit salad should she get? All of her friends really like it. Malika thinks that her 20 friends will want to have 1 cup each. At the grocery store, the deli counter sells fruit salad for $2 per cup. Malika multiplies to figure out how much it will cost. If she buys 20 cups at $2 per cup, she will have to pay $40 total. That is too much money. So, she decides to make the fruit salad herself.2020page0020page0020.xhtmlLet's2121page0021page0021.xhtmlParty Favors It is almost time for Malikas party! All that is left to do is sort the party favors. Malika is excited for this task. She wants to thank her guests for coming. And, she has a lot of fun things to give her friends.2222page0022page0022.xhtmlMalika counts 20 colorful bags. Malika wants each bag to have the same number of items. It will not be fair for some people to get more than others. Malika has marbles, pencils, paddleballs, and bubbles. First, she figures out how many favors she has. But she keeps losing count! Malika decides to keep a list. She counts the marbles and writes 100. Next, she counts the paddleballs and writes 20.2323page0023page0023.xhtmlMalika is running out of time and needs to get the favors into the bags quickly. She starts with her pile of marbles. Since she wants each bag to have the same number of marbles, she decides to use division. Malika has 100 marbles and 20 bags. That means she can put 5 marbles into each bag. She splits them into groups of 5. Next, she moves on to the paddleballs. There are 20 bags and 20 paddleballs. So, each bag gets 1. Malika hopes her friends will enjoy the party favors. She tried to choose favors that everyone will like. She cant wait for people to start arriving!2424page0024page0024.xhtmlLet's2525page0025page0025.xhtmlSurprises in Store The day has finally arrivedits party time! Malika is so excited. There are balloons everywhere, and her friends have come. They are eating pizza and playing games. The party favor bags are all lined up on the table. Malika is thankful that she can share her special day with her friends. But then, there is a really big surprise! Someone brought friends from out of town. There are 4 more people at the party. Malika planned for exactly 20 people, and now there are 24. What should she do? Should she ask them to leave? That would be an uncomfortable conversation. And Malika doesnt want to be rude. There must be a way to include them. Malika tries to think of a plan. She wants to make sure everyone gets to have some of the delicious pizza. How can she make sure that happens?2626page0026page0026.xhtml2727page0027page0027.xhtmlMalika thought she was going to have 20 guests. She ordered 6 large pizzas so each person could have 3 slices. That was a total of 60 slices of pizza. But now, that might not be enough. Malika sees that some of her guests are only eating 2 slices of pizza. Maybe there will be enough for the new friends. Malika tries to count the number of guests only eating 2 slices. But they all keep moving around! She decides to count the number of pizza slices still on the table. Malika estimates that the 4 new people will each eat 3 slices of pizza. If there are 12 slices left, Malika wont have to order more!2828page0028page0028.xhtmlLet's2929page0029page0029.xhtmlProblem Solving Liam is a guest at Malikas party. He is very excited. There are many games to play and things to do. Its hard to decide which one to do first. To help guests choose how to spend their time, a table has been posted. It shows how long each activity takes. Find out how Liam plans his time at the party by answering the questions. 1. Liam will be at the party for 45 minutes. How many times can he go in the bounce house? 2. Liam visits the bounce house twice. Next, he has his face painted. Does he have enough time to change his mind and have his face repainted? 3. Liam has 30 minutes before he has to leave. How many times can he complete the obstacle course? Will he have any time left? 4. Liam spends an equal number of minutes on each obstacle. How many obstacles could there be in the obstacle course? How many minutes can he spend on each?3030page0030page0030.xhtmlActivity Time Required obstacle course 9 minutes face painting 15 minutes bounce house 5 minutes3131page0031page0031.xhtmlGlossary aisle space with shelves on both sides where people walk through a store budget a plan for using money over a period of time decisions choices you make details small parts of things divided shared or grouped into equal parts effort energy used to do something favors small gifts given at parties include to make someone or something a part of something else multiplies adds a number to itself multiple times options choices or possibilities plan to think about the details of something before it happens sliver a very thin piece that has been cut, broken, or torn from something larger3232page0032page0032.xhtmlIndex balloons, cost, decisions, decorations, details, divided, equally, food, games, guests, multiplies, pizza, plan,3333page0033page0033.xhtmlAnswer Key Lets Explore Math page 11 : 1. 8 balloons 2. 6 balloons page 15 : 1. 6 stickers 2. 7 stickers page 17 : 1. 60 slices 2. 6 pizzas page 19 : 1. 4 bags 2. $1 3. $20 page 23 : 1. 1 bottle 2. 2 pencils 3. 5 bags 4. 6 bags page 27 : 3 small pizzas Problem Solving 1. 9 times 2.
