A comprehensive review guide to help you refresh your study. This guide is particularly useful for midterms and final exams, condensing a semester's worth of information into one concise volume.

How do you fold a sheet of paper into the shape of a whale? How do you measure the area of a pizza pie? How can you draw a circle within a circle without lifting your pencil from the paper?

Now you can discover the answers to these and other fascinating questions about elementary geometry--the study of shapes. 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.

Each of the activities is broken down into its purpose, a list of materials, step-by-step instructions, expected results, and an easy to understand explanation. Every project has been pretested and can be performed safely and inexpensively in the classroom or at home.

It’s a sun-scorched world where clouds rarely come and nothing seems to move. That is, until children ages 6 - 9 up look a little closer to find tortoises, toads, and lizards, not to mention the scary rattlesnake and scorpion. Here, plants send their roots deep into the earth to find water, beetles stand on their head and shoot a stinky spray to fight off enemies, and roadrunners whiz by sleepy turtles and nervous desert mice on their way to ... where? Kids need only light clothes and a few simple pieces of equipment to explore the enchantments of cactus country.

It’s a land of riddles, where a winter night can last for weeks and where the ground is full of water though it rarely rains or snows. Bears, hares, wolves, and foxes roam the ice-crusted earth, as flowers follow the sun as it moves across the sky. Young readers may never come to the Arctic tundra, but now it can come to them—in a book chock full of fun-to-do experiments and activities for children ages 6 and up that help them to solve some of the mysteries of this strange and forbidding world. Arctic Tundra includes a picture field guide, a glossary-index, and a resource list.
