This article describes a technology-based approach for dealing with a misconception that some students hold concerning the equivalency of geometric transformations. Students can begin to conceptualize transformations in terms of the relationship between preimage and image figures rather than focus on the motion of a figure. (Contains 7 figures.)

Presents an activity through which students develop mathematical concepts connected to area and perimeter in a rich, real-life setting and use tables, graphs, diagrams, and spreadsheets to explore the problem, see relationships, and make and test conjectures about those relationships. Encourages algebraic thinking. (SYB)

Describes five activities using the World Wide Web that teach students to experience searching, locating, and organizing data. Students learn to summarize statistics, analyze data, make conjectures, and communicate information. They interpret or create bar graphs, line graphs, histograms, and circle graphs. (PVD)
