Time-Travel Math takes an innovative approach to teaching gifted math students advanced geometry concepts by weaving an adventure-filled story with entertaining practice problems that require deep mathematical thinking. Grades 4-5




An Adventure in Multidimensional Space


Book Description

This lavishly illustrated volume provides a strikingly visual approach to geometric shapes and transformations in 2- ,3- , and 4-dimensional space. Invoking Plato's polygons, Kepler's polyhedra, and Fuller's polytopes, the author presents, by means of hundreds of beautiful illustrations (100 of them in full color), many complex designs which may be found in nature or which may be produced by computer graphics programs. This self-contained work reveals how polygons, polyhedra, and polytopes are effective tools or hieroglyphs with which we may investigate and describe the macro, medio, and micro worlds or the multi-dimensional world without any telescope or microscope and without requiring guidance from others. Forewards by Buckminster Fuller and H. S. W. Coxeter.




Foundations of Geometry


Book Description

Explains geometric theories and shows many examples.




The Wonder Book of Geometry


Book Description

How can we be sure that Pythagoras's theorem is really true? Why is the 'angle in a semicircle' always 90 degrees? And how can tangents help determine the speed of a bullet? David Acheson takes the reader on a highly illustrated tour through the history of geometry, from ancient Greece to the present day. He emphasizes throughout elegant deduction and practical applications, and argues that geometry can offer the quickest route to the whole spirit of mathematics at its best. Along the way, we encounter the quirky and the unexpected, meet the great personalities involved, and uncover some of the loveliest surprises in mathematics.




Informal Geometry Explorations


Book Description

More than 75 motivational problem-solving activities explore geometry in the natural and human worlds: counting, area, construction, congruence, visualization, symmetry, tiling, and dissection. These versatile problems introduce new topics, reinforce and review ideas, or simply serve as a change of pace. Blackline masters and answer key.




A Place for Zero


Book Description

As Zero searches to find his place, he learns of his additive and multiplicative identities, and then he establishes place value.




Sir Cumference and the First Round Table


Book Description

Join Sir Cumference, Lady Di of Ameter, and their son Radius for wordplay, puns, and problem solving in this geometry-packed math adventure. King Arthur was a good ruler, but now he needs a good ruler. What would you do if the neighboring kingdom were threatening war? Naturally, you'd call your strongest and bravest knights together to come up with a solution. But when your conference table causes more problems than the threat of your enemy, you need expert help. Enter Sir Cumference, his wife Lady Di of Ameter, and their son Radius. With the help of the carpenter, Geo of Metry, this sharp-minded team designs the perfect table conducive to discussing the perfect plan for peace. The first in Sir Cumference series, Sir Cumference and the First Round Table makes math fun and accessible for everyone.




What's Your Angle, Pythagoras?


Book Description

In ancient Greece, young Pythagoras discovers a special number pattern (the Pythagorean theorem) and uses it to solve problems involving right triangles.
