DRAWING DATA WITH KIDS

An illustrated guide to teaching visual information to children.

The key fictional conceit of Khan’s nonfiction debut is a 10-year-old girl named Pariza, whose parents are teaching the basics of data visualization to her and her younger brother “one graph at a time.” Each of the book’s chapters contains a story in which little Pariza is exposed to some new data concept or mathematical process, followed by a “time out” in which more details are provided, concluding with a “your turn to play” segment in which young readers are encouraged to try out the skills they’ve just learned. In this fictionalized setting, the author contends with a variety of simple data-representation challenges, from the basics of making a graph to ways of breaking down such statistical data as the average rainfall in each of the United States or the number of vowels and consonants in the various state names. Gradually, the subjects grow more elaborate and more complicated, always couched in the activities of Pariza’s family. In one section, Pariza and her family members keep track of each person’s score during rounds of Scrabble; Pariza then converts those scores into a graph (“she started adding dots for her score and connected them to form a line graph”). Khan’s narrative choice to render all of this as a story with identifiable characters (including resourceful Pariza, her calm, understanding parents, and her headstrong younger brother) is a wise one; the approach will allow younger readers to learn the basics of data visualization without feeling intimidated or bored. The book’s uncredited illustrations, showing not only characters and their settings but also multicolored charts and graphs, further help to demystify what might otherwise be daunting concepts. By the end of the book, Pariza is confident and ready to take on the world, and Khan’s young readers may very well feel the same way.

A brightly inviting and effective manual for teaching data visualization to younger readers.
