Children's LiteratureThis book covers topics of geometry including the undefined terms (point, line, and plane), two-dimensional and three-dimensional figures, and symmetry. There are some real world correlations, such as, the concept of surface area to the need for elephants to have large ears to create additional surface area helping them keep cool. There is a good discussion of the irrational number pi in the chapter on circles. The format of the book is question and answer. While not a textbook with complete explanations, the book is a relative easy read that explains many points that confuse students in language that relates to high school students. (There is a typographical error at the bottom of page 126 in the formula to find the height of a cylinder when the volume of the cylinder and the radius of the circular base are known. There should be no square root radical in the formula.) There are "Rx" hints scattered throughout the book that are quite helpful. The cartoon drawings contain additional information. There are numerous web sites listed at the end of each chapter where students may find additional information and activities. Some of the sites may have membership requirements. This is good resource for a math classroom. 2004, John Wiley & Sons, Ages 13 up.
