There's more to math than addition, subtraction, multiplication, and division.
Once people used math to explore shapes, all kinds of engineering feats were possible.
The ancient Egyptians used their knowledge of geometry to create impressive monuments that survive to this day. Later, ancient Greeks studied what the Egyptians and the Babylonians knew of geometry to create a formal set of geometric rules called Euclidean geometry, named for the famous philosopher and mathematician Euclid.
In the last century and a half, we've gone on to learn how fractal geometry in the natural world (clouds, rocks, and plants such as ferns) works. Fractal equations are extremely complicated, usually require a machine to solve, and are most often stored and displayed on computers.
The basics of geometry are not so difficult. You must learn the types of angles and shapes and how to determine their area, diameter, and so on. These books provide a fun introduction to beginning geometry through stories, easy explanations, and activities.
Sir Cumference, Radius, and Sir Vertex search for Edgecalibur, the sword that King Arthur has hidden in a geometric solid.
Radius is on a quest to earn his knighthood! With only a circular medallion, a mysterious poem, and his own wits to guide him, he must find and rescue a missing king. Includes plastic protractor.
Assisted by his knight, Sir Cumference, and using ideas offered by his wife and son, King Arthur finds the perfect shape for his table.

Puzzles to solve using principles of geometry.
Part of the Math Fun series.
"Packed with illustrations, Geometry for Every Kid uses simple problems and activities to teach about acute and obtuse angles, parallel and perpendicular lines, plane and space figures, and much more! By arranging the pieces of an intriguing Chinese puzzle called a tangram, you'll explore all the different shapes you can form. You'll also learn how to create a colorful 3-D drawing that seems to rise right off the page! And, by building a geoboard, you'll discover a quick, fun way to compare the area of different geometric figures."
"Inside Groovy Geometry, you’ll find all the geometry basics, plus information on how to figure out the height of any object from its shadow, find distances "as the crow flies," estimate the area of any space, and much more. While you play the Name Game and Rectangle Race, you’ll learn how to draw, measure, and identify different kinds of angles, triangles, and quadrilaterals. And with fun activities like Bull’s Eye and Pizza Party, you’ll practice plotting coordinate points on a graph and measuring the area and diameter of a circle. Most important, you’ll have a great time doing it!"

"Mathematics comes alive with Circles, a comic, full-color activity book. By playing with a flying disk, a geodesic dome, psychedelic designs, and more, kids teach themselves such concepts as pi, ellipses, and parabolas. Circles reveals the geometry of life in mazes, magic, pinwheels, pickles, and more."
