The Lemonade War by Jacqueline Davies is a smart and engaging children’s novel that blends friendship, competition, and math concepts into a relatable real-life story. The book follows siblings Evan and Jessie Treski as a simple summer lemonade stand turns into a full-scale rivalry. Sparked in part by Jessie’s decision to skip a grade, the competition becomes both a business challenge and an emotional test for the siblings. In this course, students will explore themes such as sibling relationships, fairness, empathy, and problem-solving. Through guided reading, character analysis, and real-world math applications—including money management, percentages, profit, and basic marketing strategies—students will strengthen both their reading comprehension and critical thinking skills. Each chapter introduces a key business or marketing term, helping students see how abstract concepts apply to real-life decisions and outcomes. With its realistic characters, emotional depth, and practical connections to everyday life, The Lemonade War encourages students to reflect on communication, cooperation, and personal growth, while also building early financial literacy in an age-appropriate and engaging way.
