The sun sets on the colorful canyon. The Grand Canyon Imagine staring into a 6,000-foot (1,800-meter) canyon. It is a long way to the bottom. Luckily, those who want to explore Grand Canyon National Park are not limited to staring. There are many trails that wind from the top to the bottom. Some people make the trek on foot. Others go by mule. Either way, the long trip to the bottom offers many chances to learn. And many people want to make that trip! Millions of people visit the Grand Canyon each year. They travel from around the world to see the stunning views. The rocks of the canyon are a mosaic of colors. There are shades of red, orange, and brown. And with just one look, people wonder many things. How did this form? What is it made of? And, of course, how long does it take to get to the bottom and back to the top?

Mathematical Practices and Processes • Make sense of problems and persevere in solving them. • Model with mathematics. • Attend to precision. Materials • Spectacular Sports: World’s Toughest Races books • copies of student activity sheets (pages 46–51) • paper sentence strips (one per student) • newspaper article about a race, if available TCM 27009 000 Saskia Lacey Spectacular Sports: World’s Toughest Races Lacey Tackle today’s toughest races as you learn about fractions.

Day 1 Day 2 Day 3 Day 4 Day 5 10 © Teacher Created Materials 27021—Mathematics Readers 11 Introduction Unit 2: Fractions Spectacular Sports: World’s Toughest Races Mathematics Vocabulary • equal parts • whole • fraction Before Reading 1. Ask students whether they have ever competed in a race. Generate a list of races, such as running, biking, and swimming. Brainstorm challenges participants might have to overcome for each race. 2. Explain that good readers use text features to overcome the challenges of understanding a text. Explain that sidebars, captions, and diagrams are all helpful text features. 3. Distribute the Spectacular Sports: World’s Toughest Races books to students. Have students use text features to preview the book and predict challenges that athletes might face during each race. 4. Have students predict the mathematics that might be related to the topic based on one text feature from the book. Mathematics Investigation Build Understanding 1. Read aloud from page 28 of the Spectacular Sports: World’s Toughest Races book. Ask students to imagine that Taj and three of his friends don’t want to race the entire course length just yet. To train, they’ll do a relay— they’ll each complete a section of the course. Read the vocabulary words aloud. Guide students to create student-friendly definitions. • What’s the fairest way to compete in a relay? • What makes one part of the whole course equal to another part of the whole course? • What is a math word that describes parts of a whole? 2. Distribute paper sentence strips to students. Explain that each strip represents one whole length of the course. Ask the students how they can use the strips to show the parts of the race that Taj and his three friends will complete. • Have above-level learners use additional strips with differing lengths to show how the equal-sized parts of the course change as the course length is increased or decreased. • Confirm that below-level learners and English language learners have not misinterpreted “Taj and his three friends” as a total of three people. 3. Ask students guiding questions to build understanding. • How many equal parts are in the whole? • How might folding the strip help? • If more friends want to join the relay, what happens to the size of the parts? 149 MATHEMATICS Content-Area Literacy Mathematics Readers, 2nd Edition Complete Kits Level English Spanish Price 6-Packs Kindergarten 27261 28659 $969.99 Pg. 150 Grade 1 27326 28660 $969.99 Pg. 151 Grade 2 27391 28661 $1,119.99 Pg. 152 Grade 3 27000 28662 $1,119.99 Pg. 153 Grade 4 27196 N/A $1,119.99 Pg. 154 Grade 5 27456 N/A $1,119.99 Pg. 155 Grade 6 27526 N/A $1,119.99 Pg. 156 To review and purchase individual 6-Packs with Lesson Plans and Add-On Packs, see the following pages.
