How do you fold a sheet of paper into the shape of a whale? How doyou measure the area of a pizza pie? How can you draw a circlewithin a circle without lifting your pencil from the paper? Now you can discover the answers to these and other fascinatingquestions about elementary geometry--the study of shapes. Packedwith illustrations, Geometry for Every Kid uses simple problems andactivities to teach about acute and obtuse angles, parallel andperpendicular lines, plane and space figures, and much more! Byarranging the pieces of an intriguing Chinese puzzle called atangram, you'll explore all the different shapes you can form.You'll also learn how to create a colorful 3-D drawing that seemsto rise right off the page! And, by building a geoboard, you'lldiscover a quick, fun way to compare the area of differentgeometric figures. Each of the activities is broken down into its purpose, a list ofmaterials, step-by-step instructions, expected results, and an easyto understand explanation. Every project has been pretested and canbe performed safely and inexpensively in the classroom or athome.
