Using animals in the zoo, the author explores the use of different graphs to organize and understand data.  Each two page spread explains  specific graphs such as pictographs, tallies, bar graphs, pie graphs and line graphs.  With clear, uncluttered graphics, the visuals greatly support the text.  Yet, the undersized book would be better  presented as a larger book or with a document camera, to be shared with the whole class.  I’m glad to have this comprehensive introduction to graphs to add to our collection.  Other titles in this set include primary books on analyzing data, probability and sorting.
