It took hours, but she can finally see South Africa. She shifts in her seat and hugs her stuffed elephant, Ellie, tightly. Sam's family is going to Kruger (KROO-guhr) National Park. There are many animals in the park. Sam wants to see all of them. But most of all, she wants to see elephants! Sam loves elephants. She thinks she may see some on her trip. Sam cannot wait!66page0006page0006.xhtmlElephants roam at Kruger National Park.77page0007page0007.xhtmlSam and her parents go to pick up their rental car. As her parents drive, Sam reads. Sam learns more about South Africa. She reads about Kruger National Park, too. The park is not like a zoo. There are no cages. Instead, animals live in the wild. Sam is excited to see them run free.88page0008page0008.xhtmlSam and her parents drive into Kruger National Park. South Africa99page0009page0009.xhtmlThe Camp Sam finishes her book just as the car stops. She looks out the window and sees a group of round huts. She holds up Ellie so she can see their new home. "These huts look like beehives, " Sam tells her parents. Sam makes buzzing noises as she gets out of the car. She cannot believe she gets to live here for the next five days! a hut at Kruger National Park1010page0010page0010.xhtmlLET'S EXPLORE MATH Sam's parents get a map of the huts. 1. How many rows of huts are there? 2. How many columns of huts are there? 3. How many total huts are there?1111page0011page0011.xhtmlSam looks out over the camp. She thinks it looks so beautiful. Next to her hut, there is a river. Sam starts to imagine crocodiles in the water. Scared, Sam hurries inside the hut. The inside of the hut is nice and cool. Sam looks up to see a ceiling fan. She starts to look back down and does a double take. The ceiling is made of grass! Sam looks out over the camp.1212page0012page0012.xhtmlgrass ceiling1313page0013page0013.xhtmlSafari Time! The next morning, Sam wakes up early. She runs to her parents' bed and shakes her mom and dad awake. "Time to see some elephants! " Sam yells. She jumps around in circles. Today is the day! Sam gets dressed and grabs Ellie. She puts Ellie in her backpack but makes sure her head is sticking out. That way, Ellie can see some elephants, too! This sign has both English and Tsonga phrases.1414page0014page0014.xhtml1515page0015page0015.xhtmlThere are many ways to see animals in Kruger National Park. You can walk, drive, or even ride a horse. Sam's parents pay someone to drive them through the park. That way, they can take their time and take pictures as they go. Sam climbs into her seat, but she can barely sit still. She is too excited! Sam cranes her neck for a chance to spot an elephant.1616page0016page0016.xhtmlsafari truck in the park1717page0017page0017.xhtmlAs they make their way through the park, Sam looks for animals. Suddenly, the truck stops. Sam grabs her binoculars from her backpack. As she looks out over the park, she sees something move. It is a family of giraffes! One is eating leaves from the top of a tall tree. Sam has seen her first animal! Sam uses her binoculars.1818page0018page0018.xhtml1919page0019page0019.xhtmlLater that morning, Sam sees her mom look off to the left. Her dad points at something in the distance. At first, Sam does not see anything. Then, she sees a gray blur. "That is a white rhino, " Sam whispers to her parents. "It is called a white rhino, even though it is gray. " The rhino is drinking from a watering hole. "It cannot see us, but I am sure it smells us, " Sam says. baby white rhino2020page0020page0020.xhtmladult white rhino LET'S EXPLORE MATH Sam and her parents watch a group of rhinos visit the watering hole. Sam counts 12 white rhinos. 1. Use 12 square tiles or counters to stand for the rhinos. Build an array. 2. Describe the array by completing the sentence frame : My array has _____ rows and _____ columns. I know there are 12 objects because __________. 3. What other arrays can be built using 12 objects? How do you know?2121page0021page0021.xhtmlAfter seeing the rhinos, Sam's mom says it is time to go back to the hut for lunch. "But when will we see elephants? " Sam asks. Sam's mom tells her that they still have four days left on their trip. Sam pats Ellie. "We will see one of your friends tomorrow. I promise, " she whispers to Ellie.2222page0022page0022.xhtml2323page0023page0023.xhtmlEarly Mornings For the next few days, Sam wakes up early. She grabs Ellie and runs out to meet the truck driver. She knows each day might be the day she will see elephants! Sam spots more animals. One day, she hears a pride of lions roar. The next day, she watches a herd of buffalo running. She spies leopards sleeping, too. But still, she does not see any elephants. A group of lions is called a pride.2424page0024page0024.xhtmlLET'S EXPLORE MATH African buffalo2525page0025page0025.xhtmlWhat Is That Sound? On the fifth day, Sam wakes up slowly. She does not jump out of bed this time. Instead, she is disappointed. It is her last day, and she still has not seen a single elephant! She hears her dad calling for her. Sam slowly makes her way to the front door. As she gets closer, she hears the sound she has been waiting all week to hear. It sounds just like a trumpet!2626page0026page0026.xhtml2727page0027page0027.xhtmlSam rips the door open and sees it. An elephant is in the distance! And there is not just one elephant. There is a whole herd! Sam grabs Ellie and holds her up. "Look! " Sam shouts. "It is your family! " Sam and her parents watch the herd of elephants before they have to leave. Sam even gets pictures of the herd to hang on her bedroom walls. On the way home, Sam cannot stop talking about the elephants. She thinks it was the best trip ever. Sam hopes they can come back again one day! A herd of elephants plays in a watering hole.2828page0028page0028.xhtmlLET'S EXPLORE MATH Sam looked carefully at the herd of elephants. Now, look carefully at this array. 1. How many elephants are there? How do you know? 2. Which expressions show the total number of elephants? A. 5 + 4 B. 4 + 4 + 4 + 4 C. 5 + 5 + 5 + 5 D. 5 + 4 + 5 + 4 E. 4 + 4 + 4 + 4 + 4 F. 5 + 5 + 5 + 5 + 52929page0029page0029.xhtmlProblem Solving Sam sees a group of bushpigs in Kruger National Park. She wants to remember them. So, when she gets home, she decides to make a bushpig page in her scrapbook. She wants to describe the number of bushpigs in the group in different ways. Help Sam complete her scrapbook page by answering the questions. 1. Sam sees 18 bushpigs on the trip. Use 18 square tiles or counters to stand for bushpigs. Build all of the possible arrays of 18. 2. Draw all of the arrays on grid paper. 3. Write an equation using repeated addition to describe each array.3030page0030page0030.xhtmlbushpig3131page0031page0031.xhtmlGlossary binoculars a device that is used to see things blur something that is unclear cranes stretches to see something better disappointed feeling sad because something did not happen herd a group of animals that live together huts small, simple houses or buildings pride a group of lions rental something that can be used in return for payment watering hole a small pond or lake used by animals for drinking3232page0032page0032.xhtmlIndex buffalo, bushpigs, crocodiles, elephants giraffes huts leopards lions South Africa white rhino3333page0033page0033.xhtmlAnswer Key Let's Explore Math page 9 : 1. 4 rows of huts 2. 2 columns of huts 3. 8 huts total page 19 : 1. Arrays will vary but may include 1 row and 12 columns, 2 rows and 6 columns, 3 rows and 4 columns, or other arrays that total 12 white rhinos. 2. Sentences will vary. Example : My array has 4 rows and 3 columns. I know there are 12 objects because I can skip count by 4s to 12. 3. Answers will vary but may include 1 row and 12 columns, 3 rows and 4 columns, or 6 rows and 2 columns. page 23 : Arrays should show 5 rows and 3 columns; There are 15 buffalo; Answers will vary but may include skip counting, 5 + 5 + 5, or 3 + 3 + 3 + 3 + 3. page 27 : 1. There are 20 elephants; Answers will vary but may include skip counting or writing expressions for the array. 2. C and E Problem Solving 1. Arrays will vary, but may include 1 row and 18 columns, 2 rows and 9 columns, 3 rows and 6 columns, 6 rows and 3 columns, 9 rows and 2 columns, or 18 rows with 1 column. 2.

What is the difference between rows and columns? 2. How can having objects arranged in arrays help you quickly count them? 3. Sean writes in his math journal that he can make an array with only one item. Describe Sean's array. 4. Jos writes 2 + 2 + 2 + 2 + 2 + 2 to express 12. Doug writes 6 + 6 to express 12. If both of them build arrays to show their expressions, how will the arrays be similar and different? 5. Do you think it is easier to create an array when the number of objects is given, or to find the number of objects when an array is shown? Why? 6. Describe times where a wildlife park ranger might use repeated addition.3535page0035page0035.xhtmlTravel Adventures Kruger National Park Repeated Addition Get ready to gaze at giraffes, look at leopards, and behold buffalo.
