El fuerte (The Fort)

There is a contest at a school to design a new playground. The students use blocks to build their models. As they build, they use three-dimensional shapes. Some students build a train out of blocks for the younger students to play on. Can you guess which three-dimensional shape they use for the train's wheels? Read to find out which design wins.

Find three-dimensional shapes in a fort! This fun title, that has been translated into Spanish, challenges children to find cylinders, cones, and pyramids in a fort while introducing them to terms like base, vertex, face, and more! Young readers will improve their STEM skills and learn how to recognize these three-dimensional shapes all around them! Vibrant images, clear examples, and helpful mathematical diagrams work together to make geometry seem easy and fun!

This book presents conventions, mathematical concepts, definitions and applications central to the geometric modeling of solids, shells and wires (engineering jargon) embedded in 3D space. Currently, software is available for geometric modeling of technical or natural scenarios. However, the models built frequently fail in supporting the subsequent engineering computing and simulations. Only after repeated iterations and re-design, the models permit engineering / science simulations. This book endows the reader with the basic mathematical concepts needed to ensure that the geometric models...

La segunda edición de Lógica DGB cobra expresión en las reformas de actualización emprendidas por la Dirección General de Bachillerato (DGB), misma que pretende dar cumplimiento a la finalidad del Bachillerato que es "generar en el estudiantado el desarrollo de una primera síntesis personal y social que le permita su acceso a la educación superior, a la vez que le dé una comprensión de su sociedad, su tiempo y le prepare para su posible incorporación al trabajo productivo".

El objetivo de este libro es cubrir exhaustivamente los contenidos de un curso sobre el análisis de la independencia y la asociación entre dos variables cualitativas a partir de la información muestras recogida en forma de tabla de contingencia bidimensional. Para conseguir este propósito se proporcionan todas las herramientas necesarias para los desarrollos teóricos, así como un software estadístico para la implementación de las técnicas presentadas y la resolución de los ejercicios propuestos al final de cada capitulo, de modo que esta monografía constituya una herramienta útil...

What is the arithmetic triangle? What is the purpose of the summation symbol? How did the architects of the 17th century calculate their structures? These and many other questions about Mathematics will be solved in this enjoyable and revealing book.
