Produktbeschreibung

¡Las desarrollos des poliedros brindan muchas horas de diversión fascinante! Cada red representa la superficie de una forma geométrica única. Algunas de las formas fueron descritas hace 2500 años. Una desarrollos des poliedros es un dibujo plano que se puede cortar y doblar para formar una figura tridimensional. Por ejemplo, seis cuadrados idénticos se pueden convertir en un cubo. Esto se debe a que un cubo tiene seis lados, todos los cuales son cuadrados idénticos. Cada uno de los dibujos de este libro se puede cortar y doblar para formar un objeto geométrico tridimensional. Este libro contiene 80 desarrollos des poliedros, que incluyen: Antiprisma triangular bialargada Cono Cubo Cuboctaedro Cilindro Antiprisma Dekagonal Prisma decagonal Icositetraedro deltoidal Dado Hexaquisoctaedro Dodecaedro regular Cúpula pentagonal alargado Bipirámide pentagonal alargado Pirámide pentagonal alargado Bipirámide cuadrada alargada Pirámide cuadrada alargada Antiprisma triangular alargado Cúpula triangular alargado Bipirámide triangular alargado Pirámide triangular alargado Tronco de pirámide decagonal Tronco de pirámide cuadrilátera Tronco de pirámide triangular Gran Dodecaedro Gran dodecaedro estrellado Giroelongada pirámide pentagonal Dipirámide cuadrado giroelongada Prisma cuadrado giroelongada Giroelongada pirámide cuadrada Pirámide heptagonal Heptaedro 4,4,4,3,3,3,3 Heptaedro 5,5,5,4,4,4,3 Heptaedro 6,6,4,4,4,3,3 Prisma hexagonal Pirámide hexagonal Hexaedro 4,4,4,4,3,3 Hexaedro 5,4,4,3,3,3 Hexaedro 5,5,4,4,3,3 Icosaedro regular Icosidodecaedro Pirámide cuadrada oblicua Antiprisma oktagonal Octaedro regular Antiprisma Pentagonal Cúpula pentagonal Bipirámide pentagonal Prisma pentagonal Pirámide pentagonal Rotonda pentagonal Prisma pentagramma Pirámide rectangular Prisma rómbico Rombicuboctaedro Pequeño rhombidodecaedro Dodecaedro estrellado Pequeño Cubo romo Dodecaedro romo Antiprisma cuadrado Cúpula cuadrada Pirámide cuadrado Trapezoedro cuadrada Estrella goctángula Tetraedro regular Tetraquishexaedro Triaquisoctaedro Triaquistetraedro Cúpula triangular Bipirámide triangular Triangular pentaedro Prisma triangular Pirámide triangular oblicua Cubo truncado Cuboctaedro truncado Dodecaedro truncado Icosaedro truncado Truncado icosidodecaedro Octaedro truncado Tetraedro truncado Pirámide estrella pentagonal derecho Trapezoedro cuadrado truncado

Autorenporträt

After 30 years of software development, David McAdams was looking for something new to do. He turned his attention to how maths is taught. Through his coursework at Utah Valley University, he learned how critical vocabulary acquisition is to all learning, and especially to maths. 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 maths 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 describing 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 notations defined; in excess of 790 illustrations; an IPA pronunciation guide; and greater than 1400 formulas and equations. While working on the dictionary, between playing with his grandchildren, Mr. McAdams started developing other ideas for maths literacy. The results are "Numbers", "What is Bigger than Anything (Infinity)", "Swing Sets (Set Theory)", and "Learning with Play Money". Branching out, Mr. McAdams took a departure from tools for teaching maths, moving into the arena of pure mathematical delight. This results in two volumes of "My Favorite Fractals". While reading a book on colour names to his grandson Sawyer, he got to thinking how boring books on colour names are for adults. "What in the natural," he mused, "has enough of the primary and secondary colours to teach colour names to children?" His first answer was either frogs or parrots. He created "Parrot Colours", "Flower Colours", and "Space Colours". Returning to maths, 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 maths 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 maths learners become fascinated with how maths works. Mr. McAdams wrote "One Penny, Two" to illustrate through a stories 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.
