Les patrons géométriques offrent de nombreuses heures de plaisir fascinant ! Chaque filet représente la surface d'une forme géométrique unique. Certaines formes ont été décrites il y a 2 500 ans. Un patrons géométriques est un dessin plat qui peut être découpé et plié pour former une figure tridimensionnelle. Par exemple, six carrés identiques peuvent former un cube. En effet, un cube a six côtés, qui sont tous des carrés identiques. Chacun des dessins de ce livre peut être découpé et plié pour former un objet géométrique tridimensionnel. Ce livre contient 80 patrons géométriques, dont : Bi-allongée antiprisme triangulaire Cône Cube Cuboctaèdre Cylindre Antiprisme décagonal Prisme décagonaldécagonal Icositétraèdre trapézoïdal Dé Hexakioctaèdre Dodécaèdre régulier Coupole décagonale allongée Diamant pentagonal allongé Pyramide pentagonale allongée Diamant carré allongé Pyramide carrée allongée Antiprisme triangulaire allongée Coupole triangulaire allongée Diamant triangulaire allongé Pyramide triangulaire allongée Tronc d'une pyramide décagonale Tronc d'une pyramide quadrilatère Tronc d'une pyramide triangulaire Grand dodécaèdre Grand dodécaèdre étoilé Pyramide pentagonale gyroallongée Diamant carré gyroallongé Prisme carré gyroallongé Pyramide carrée gyroallongée Pyramide heptagonal Heptaèdre 4,4,4,3,3,3,3 Heptaèdre 5,5,5,4,4,4,3 Heptaèdre 6,6,4,4,4,3,3 Prisme hexagonal Pyramide hexagonal Hexaèdre 4,4,4,4,3,3 Hexaèdre 5,4,4,3,3,3 Hexaèdre 5,5,4,4,3,3 Icosaèdre régulier Icosidodécaèdre Pyramide carrée oblique Antiprisme octogonal Octaèdre régulier Antiprisme pentagonal Coupole décagonale Diamant pentagonal Prisme pentagonal Pyramide pentagonale Rotonde décagonale Prisme pentagrammique Pyramide rectangulaire Prisme losange Petit rhombicuboctaèdre Petit rhombidodécaèdre Petit dodécaèdre étoilé Cube adouci Dodécaèdre adouci Antiprisme carré Coupole octogonale Pyramide à base carrée Antidiamant à base carrée Octangle étoilé Tétraèdre régulier Tétrakihexaèdre Triakioctaèdre Triakitétraèdre Coupole hexagonale Diamant triangulaire Pentaèdre triangulaire Prisme triangulaire Pyramide triangulaire oblique Cube tronqué Cuboctaèdre tronqué Dodécaèdre tronqué Icosaèdre tronqué Icosidodécaèdre tronqué Octaèdre tronqué

Meet the Author: David E. McAdams David E. McAdams is a storyteller, educator and lifelong explorer of ideas. With a career that spans decades in mathematics education and a deep love for writing, David has authored a wide array of books that blend learning with imagination. His work ranges from playful puzzle collections for young children to detailed explorations of mathematical constants, vocabulary guides and interactive learning resources-all designed to open doors to discovery. David's journey began in the classroom, where he spent time teaching high school math and discovering a truth that would guide his work ever after: children learn best when they're engaged, curious and having fun. Over time, he noticed a critical gap in math education-students were struggling not just with concepts, but with the language of math itself. That insight led him to create All Math Words Dictionary, a comprehensive and kid-friendly resource to strengthen math vocabulary and improve comprehension. But David didn't stop there. He began to write math-inspired books for young readers, books that delight as they teach. In One Penny, Two, a magical penny-doubling story unfolds with charm and wit. In What Is Bigger Than Anything?, children are introduced to the mind-stretching idea of infinity. His My Favorite Fractals and Geometric Nets Project Books invite children to explore patterns, numbers and geometry in tangible, joyful ways. David's books are often playful, poetic and themed with real-world wonder: dinosaurs, fairy tales, space, stuffed animals, hide-and-seek, even swing sets. Each story or puzzle is crafted not only to teach, but to spark imagination. His recent projects include a collection of hundreds of math puzzles for six-year-olds and a themed series that blends math with everything kids love-ice cream cones, treasure hunts, magic tricks and more. His work has been translated into several languages, including Bengali, making his joyful approach to learning accessible to even more children around the world. Whether he's counting stars or exploring the digits of Pi, David brings a deep sense of care and curiosity to every page. Now retired from teaching, David enjoys gardening and the creative joy of writing. He continues to write daily, constantly dreaming up new ways to help children see the beauty of math, the power of language and the magic of asking, "What if?"
