  From the plate on the table to the moon in the sky, from the flat to the three-dimensional there's a world of shapes around the reader. This book looks at these and shows how these shapes are defined mathematically. It encourages the reader to find out how to draw and make them. and discover what fun can be had just looking around and recognizing the shapes to be seen. From a simple description of circles, the text expands to concentric circles, annulus, spinning and turning, interlocking teeth on circles and the making of a super spinner, drawing circles and circular patterns and the parts of a circle such as a crescent as in the moon. Other shapes are then described: an oval and an ellipse with the added interest of a puzzle called the magic egg; curves - open or closed, straight to curved, curved patterns; rings and loops - a 3-D shaped form from a curve is a torus, a cylinder - cylinder supports, moving with cylinders, lifting with cylinders, tubes and pipes - veins , musical instruments, scaffolding, tunnels; spheres - games with spheres, parts of a shere and lines around the globe.
