Not a Bean

October 1, 2019
Martínez reveals the hidden secrets of the legendary Mexican jumping beans in her picture-book debut. As the title asserts, the jumping bean is "not a bean" but the seed pod of a desert plant known as the yerba de la flecha, which hides a secret stowaway. A female moth has laid her eggs near the seed pods of the yerba plant, and when they hatch, the caterpillars crawl inside, using the seed pod for protection and sustenance before pupating and emerging as adult moths. As a seed-encased caterpillar jumps around the desert floor seeking shelter and safety, readers count along in Spanish while learning vocabulary related to the desert ecosystem: cascabeles (rattlesnakes) and arroyos (streams), for example. González's bright, friendly illustrations depict a vibrant desert teeming with life--far from the desolation often associated with its dry climate. "Siete amigos" also join the proceedings, depicted in varying shades of tan and peach, appearing to represent some of the diversity in skin tone among Mesoamerican peoples. Much like the seed pods' concealed cargo, this informational picture book packs plenty of facts and learning moments into a thoroughly entertaining package. Engaging and fun, as all learning should be. (glossary, author's note) (Informational picture book. 4-8)

PreS-Gr 2-In the desert of Mexico, something special is happening inside of a yerba de la flecha plant. A caterpillar larva burrows its way into the seedpod of the shrub, where it grows by drinking the water that seeps into it. When the seedpod falls to the ground, the caterpillar is tucked inside, jumping when necessary to escape the heat of the desert or get to safety. A group of children come upon the "jumping bean" and add it to their game, hoping it will "jump" to a specific spot as they observe it. Soon, though, the bean goes still to become something entirely new. This impeccably designed book tells the story of the Mexican jumping bean. Though not a bean at all, this plant has nonetheless made a memorable name for itself through its unusual nature. Thoughtful, detailed illustrations transport readers through the Mexican desert as the caterpillar completes its journey. The text introduces Spanish words while counting from one to 10 throughout the story. VERDICT This is an excellent read-aloud for elementary school children, especially those who are looking for a gentle introduction to the Spanish language and some accompanying cultural connections. Fans of Roseanne Greenfield Thong's Green Is a Chili Pepper will appreciate the design similarities.-Mary Lanni, formerly at Denver Public Library
