In Groovy Geometry, after a tour of the fundamental geometric concepts and definitions, kids will move on to master all of the geometry essentials, including drawing, measuring, and identifying the different kinds of angles, triangles, and quadrilaterals; using the Pythagorean theorem to find a hypotenuse; measuring the diameter, circumference, and area of a circle; and computing the volume of a cylinder. Along the way they'll learn to figure out the height of any object from its shadow, judge distances as the crow flies, estimate the area of any space, and much more. Designed to be fun for kids who are wary of math as well as those who excel at it
