*Mathematics Instruction; *Problem Solving

This paper presents two examples in which technology, in this case a fairly sophisticated authoring system--ToolBook, was used as a tool to construct student understandings in mathematics. In doing so, students were able: (1) to successfully identify the variables (unknowns) and the information given (data) in the problem; and (2) to create meaningful links between the data and givens which enable successful problem solution. Examples are from work in a seventh grade pre-algebra class of below-average-ability students in a middle class urban setting and are from a single classroom.
