The magic is dying. The trees are fading. And one girl without a branch might be the only one who can figure out why.
Beth Turley’s middle-grade novel “The Last Tree Town” follows twelve-year-old Cassi, a math-loving seventh grader who struggles with her Puerto Rican identity because her red hair and fair skin don’t match others’ expectations. As Cassi joins Math Olympics at school, she befriends Aaron, a new student who shares stories about the various “tree towns” he’s lived in. Meanwhile, Cassi grapples with her older sister Daniella’s sudden withdrawal and depression, as well as her grandfather’s Alzheimer’s diagnosis. This heartfelt coming-of-age story weaves mathematics throughout the narrative as Cassi tries to find solutions to life’s complex problems.
“The Last Tree Town” offers educators a meaningful entry point for discussing both SDG 15 (Life on Land); the book’s focus on “tree towns” provides opportunities to explore community relationships with nature and the importance of preserving green spaces. Cassi demonstrates being reflective, caring, and open-minded through her journey of self-discovery and her empathetic response to family challenges. Teachers can use this book as a springboard for mathematical storytelling activities where students create their own “tree town” stories that incorporate environmental themes. The book’s sensitive treatment of cultural identity, mental health, and belonging also makes it valuable for classroom discussions about inclusion and community support.
