It's Elementary! Geometry for Grade School Students

Anno

Games that guide learning about abstract thinking, circuitry, geometry, and topology.

"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."
Jo Phillips

A few folds of paper reveal mysteries of the triangles.

"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!"
Part of the Magical Math 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."
