How do you show numbers with a circle? Easy as pie! Have fun making and using pie graphs to compare amounts.
Children's Literature - Melissa J. RickeyBrightly colored photographs carefully matched with simple and direct text facilitate children's mathematical thinking and comprehension. Brief chapters entitled "Circle are Wholes," "Making a Pie Graph," "Favorite Foods," "Spending Time and Money," and "How You Spend Your Day" define and demonstrate how pie graphs are made and illustrate the forms that such graphs can take. For example, a series of photographs illustrates that pie graphs "show how parts compare to the whole," and that a pie graph can compare the number of girls and boys on a jump rope team. "The key shows pink for girls and blue for boys. Half the circle is pink. Half the circle is blue." The pie graph concept is reinforced with further examples that compare which kind of pizza is the favorite, the amount of time spent in and out of school in a week, and how much time in a week is spent on different activities. Other features integral to the book's design include a table of contents, glossary, a list of further readings, internet sites, and an index. Teachers can use this book as a read aloud in primary classrooms and for early readers' independent reading. This nonfiction picture book is part of the "Making Graphs Series," which introduces young readers to graphing concepts. Reviewer: Melissa J. Rickey
