The first author, a student in a graduate children's literature class, designed a project to locate "good" mathematics-based children's literature selections. However, the reference tools usually consulted (e.g., "Books in Print") to locate books by topic were of little help, and those she located under individual mathematics topics were mostly traditional mathematics books rather than good read-aloud selections. Consequently, she perused the university library's sizeable juvenile collection to find books that would meet her selection criteria. This article describes the influence of two landmark documents for mathematics teaching and learning--Curriculum and Evaluation Standards for School Mathematics" (National Council of Teachers of Mathematics [NCTM], 1989) and "Principles and Standards for School Mathematics" (NCTM, 2000)--as she engaged in the process.
