Le sviluppo piano di poliedri offrono molte ore di divertimento affascinante! Ogni rete rappresenta la superficie di una forma geometrica unica. Alcune forme furono descritte già 2500 anni fa. Una sviluppo piano di poliedri è un disegno piatto che può essere tagliato e piegato in una figura tridimensionale. Ad esempio, sei quadrati identici possono essere trasformati in un cubo. Questo perché un cubo ha sei lati, che sono tutti quadrati identici. Ciascuno dei disegni di questo libro può essere tagliato e piegato in un oggetto geometrico tridimensionale. Questo libro contiene 80 sviluppi piano di poliedri, tra cui: Antiprisma triangolare dielongata Cone Cubo Cubottaedro Cilindro Antiprisma decagonale Prisma decagonale Icositetraedro trapezoidale Dado Esacisottaedro Dodecaedro regolari Cupola pentagonale elongata Dipiramide elongata pentagonale Piramide pentagonale elongata Dipiramide elongata quadrata Piramide quadrata elongata Antiprisma triangolare elongata Cupola triangolare elongata Bipiramide triangolare elongata Piramide triangolare elongata Tronco di piramide decagonal Tronco di piramide quadrata Tronco di piramide triangolare Grande dodecaedro Grande dodecaedro stellato Piramide pentagonale giroelongata Dipiramide giroelongata quadrata Prisma giroelongata quadrata Piramide giroelongata quadrata Pyramide ettagonale Ettaedro 4,4,4,3,3,3,3 Ettaedro 5,5,5,4,4,4,3 Ettaedro 6,6,4,4,4,3,3 Prisma Esagonale Pyramide Esagonale Esaedro 4,4,4,4,3,3 Esaedro 5,4,4,3,3,3 Esaedro 5,5,4,4,3,3 Icosaedro regolare Icosidodecaedro Piramide quadrata obliquo Antiprisma ottagonale Ottaedro regolare Antiprisma pentagonale Cupola pentagonale Dipiramide pentagonale Prisma pentagonale Piramide pentagonale Rotunda pentagonale Prisma di una stella pentagonale Piramide rettangolare Prisma rombico Rombicubottaedro Piccolo rombicubottaedro Piccolo dodecaedro stellato Cubo simo Dodecaedro simo Antiprisma quadrata Cupola quadrata Pyramide quadrata Trapezoedro quadrata Stella octangula Tetraedro regolare Tetracisesaedro Triacisottaedro Triacistetraedro Cupola triangolare Dipiramide triangolare Pentaedro triangolare Prisma triangolare Piramide triangolare obliquo Cubo troncato Cubottaedro troncato Dodecaedro troncato Icosaedro troncato Icosidodecaedro troncato Ottaedro troncato Tetraedro troncato

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?"
