Geometrijske mree zagotavljajo veliko ur öarljive zabave! Vsaka mrea predstavlja povrino edinstvene geometrijske oblike. Nekatere oblike so bile opisane e pred 2500 leti. Geometrijska mrea je ploska risba, ki jo je mogöe razrezati in zloiti v tridimenzionalno figuro. Na primer, est enakih kvadratov je mogöe sestaviti v kocko. To je zato, ker ima kocka est stranic, od katerih so vse enaki kvadrati. Vsako risbo v tej knjigi je mogöe razrezati in zloiti v tridimenzionalni geometrijski predmet. Ta knjiga vsebuje 80 geometrijskih mre, vkljüno z: Bipodaljano tristrana antiprizma Stoec Kocka Kubooktaeder Valj Desetstrana antiprizma Desetstrana prizma Deltoidni ikozitetraeder Igralna kocka Disdiakisni dodekaeder Pravilni dodekaeder Podaljana petstrana kupola Podaljana petstrana bipiramida Podaljana petstrana piramida Podaljana kvadratna bipiramida Podaljana kvadratna piramida Podaljana trikotni antiprizma Podaljana tristrana kupola Podaljana tristrana bipiramida Podaljana tristrana piramida Prisekana iz desetstrana piramide Prisekana tirikotne piramide Prisekana trikotne piramide Veliki dodekaeder Veliki zvezdni dodekaeder Giro podaljana petstrana piramida Giro podaljana kvadratna bipiramida Giro podaljana kvadratna prizma Giro podaljana kvadratna piramida Sedemstrana piramida Heptaeder 4,4,4,3,3,3,3 Heptaeder 5,5,5,4,4,4,3 Heptaeder 6,6,4, 4,4,3,3 eststrana prima eststrana piramida Heksaeder 4,4,4,4,3,3 Heksaeder 5,4,4,3,3,3 Heksaeder 5,5,4,4,3,3 Pravilni ikozaeder Ikozidodekaeder Poevna kvadratna piramida Osemstrana antiprizma Pravilni oktaeder Petstrana antiprizma Petstrana kupola Petstrana bipiramida Petstrana prizma Petstrana piramida Petstrana rotunda Pentagramska prizma Pravokotni prizma Rombi¿ni prizma Rombikubooktaeder Mala rombidodekaeder Mali zvezdni dodekaeder Prirezana kocka Prirezana dodekaeder Kvadratna antiprizma Kvadratna kupola Kvadratna piramida Kvadratna trapezoeder Devetinpetdeset oktaeder Pravilni Tetraeder Tetrakisni heksaeder Triakisni oktaeder Triakisni tetraeder Tristrana kupola Tristrana bipiramida Tristrana pentaeder Tristrana prizma Poevna trikotna piramida Prisekan kocka Prisekan kubooktaeder Prisekan dodekaeder Prisekan ikozaeder Ikozidodekaeder Prisekan oktaeder Prisekan tetraeder Pravica petstrana zvezdni piramida Prisekan kvadratna trapezoeder

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?"
