Uma planificaçãos de poliedross é um desenho plano que pode ser cortado e dobrado em uma figura tridimensional. Por As planificaçãos de poliedross proporcionam muitas horas de diversão fascinante! Cada rede representa a superfície de uma forma geométrica única. Algumas das formas foram descritas há 2.500 anos. Uma planificaçãos de poliedross é um desenho plano que pode ser cortado e dobrado em uma figura tridimensional. Por exemplo, seis quadrados idênticos podem ser transformados em um cubo. Isso ocorre porque um cubo tem seis lados, todos quadrados idênticos. Cada um dos desenhos deste livro pode ser cortado e dobrado em um objeto geométrico tridimensional. Este livro contém 80 planificaçãos de poliedross: Antiprisma triangular bialongada Cone Cubo Cuboctaedro Cilindro Antiprisma decagonal Prisma decagonal Icositetraedro deltoidal Dado Dodecaedro disdiakis Dodecaedro regular Cúpula pentagonal alongada Bipirâmide pentagonal alongada Elongated Pentagonal Pyramid Bipirâmide quadrada alongada Pirâmide quadrada alongada Antiprisma triangular alongada Cúpula triangular alongada Bipirâmide triangular alongada Pirâmide triangular alongada Tronco de uma pirâmide decagonal Tronco de uma pirâmide quadrilátero Tronco de uma pirâmide triangular Grande Dodecaedro Grande dodecaedro estrelado Pirâmide pentagonal giralongada Bipirâmide quadrada giralongada Prisma quadrada giralongada Pirâmide quadrada giralongada Pirâmide heptagonal Heptahedron 4,4,4,3,3,3,3 Heptahedron 5,5,5,4,4,4,3 Heptahedron 6,6,4,4,4,3,3 Prisma hexagonal Pirâmide hexagonal Hexahedron 4,4,4,4,3,3 Hexahedron 5,4,4,3,3,3 Hexahedron 5,5,4,4,3,3 Icosaedro regular Icosidodecaedro Pirâmide quadrado oblíquo Antiprisma octogonal Octaedro regular Antiprisma pentagonal Cúpula pentagonal Bipirâmide pentagonal Prisma Pentagonal Pirâmide pentagonal Rotunda pentagonal Prisma pentagrama Pirâmide rectangular Prisma rômbica Rombicuboctaedro Dodecaedro rômbico Pequeno dodecaedro estrelado Cubo snub Dodecaedro snub Antiprisma quadrado Cúpula quadrada Pirâmide quadrada Trapezoedro quadrado Stella octangula Tetraedro regular Hexaedro tetrakis Octaedro triakis Tetraedro triakis Cúpula triangular Bipirâmide triangular Pentaedro triangular Prisma triangular Pirâmide triangular oblíqua Cubo truncado Cuboctaedro truncado Dodecaedro truncado Icosaedro truncado Icosidodecaedro truncado Octaedro truncado Tetraedro truncado Pirâmide pentagrama reto Trapezoedro quadrado truncado

After 30 years of software development, David McAdams was looking for something new to do. He turned his attention to how math is taught. Through his coursework at Utah Valley University, he learned how critical vocabulary acquisition is to all learning, and especially to math. Math has long been regarded as its having its own language, with its own syntax and symbols. The acquisition of this language has been found to be a barrier to many students. After the completion of his internship, Mr. McAdams finished compiling math vocabulary words into a comprehensive dictionary, written for middle school and high school students. All Math Words Dictionary is the culmination of ten years work collecting, classifying and defining all of the words a student might encounter in their studies of algebra, geometry, and calculus. This book has over 3000 entries; more than 140 math notations defined; in excess of 790 illustrations; an International Phonetics Alphabet (IPA) pronunciation guide; and greater than 1400 formulas and equations. While working on the dictionary, between playing with his grandchildren, Mr. McAdams started developing more ideas for math literacy. The results are Numbers, What is Bigger than Anything (Infinity), Swing Sets (Set Theory), and Learning with Play Money Activity Kit. Branching out, Mr. McAdams took a departure from tools for teaching math, moving into the arena of pure mathematical delight. This results in two volumes of My Favorite Fractals, filled withing stunning high-resolution images of fractal art. While reading a book on color names to his grandson Sawyer, he got to thinking how boring books on color names are for adults. What in nature, he mused, has enough of the primary and secondary colors to teach color names to children? His first answer was either frogs or parrots. He created Parrot Colors, Flower Colors, and Space Colors. Then, on a whim, he wrote If I Had a Monster, a book for preschoolers where monsters represent loving people in their lives. Fascinated by recent advances in knowledge about life in the deep ocean, Mr. McAdams researched and wrote Monster Creatures of the Deep Sea. Explore the ecosystem of the deep sea, and read about 44 bizarre creatures that live there. Returning to math, Mr. McAdams created a book to help children learn shapes, called Shapes. He remembered how, in his youth, he found a few printouts of geometric nets and was fascinated how they folded together into complex, 3-dimensional objects. He prepared Geometric Nets Project Book, then Geometric Nets Mega Project Book with many geometric nets to cut out and assemble. What can one get for the math aficionado who has everything? Mr McAdams created the books The First Million Digits of Pi, The First Million Digits of e, The Square Root of Two to One Million Digits, The First Hundred Thousand Prime Numbers. Many young math learners become fascinated with how math works. Mr. McAdams wrote One Penny, Two to illustrate through a story how fast powers of two increase with each iteration. Jerry is given a magic box. If you put a penny in it, the pennies double each day as long as none are taken out. Jerry decides he wants a dark green convertible sports car. Follow Jerry's trials as he sets his sights on his goal.
