Introductory Challenge 

Ever since she was young, Lucie loved dolphins. During classroom reading time one day, she finds a book about dolphins on the shelf and excitedly takes it to her seat. Her teacher, Mr. Wright, tells her that it’s written for older kids, but encourages her to try reading it. As she’s reading, Lucie comes to a word she doesn’t recognize: echolocation. Lucie tries the strategies she knows for decoding unfamiliar words. But sounding it out with phonetic clues isn’t helping. Before Lucie gets frustrated, how might you help her decode the word?
