The 14 computer investigations listed below are from Mathematics For Elementary Teachers: A Conceptual Approach, Fourth Edition. These investigations pose questions to generate interest in various mathematical topics from the text and encourage students to formulate and investigate their own conjectures. One use for the investigations is for term papers in which students report on their conjectures and patterns. The Mathematics Investigator software has a program for conveniently generating large amounts of data for each of these investigations.
