This activity uses CAS(TI-89) to investigate patterns in factoring and expanding. Through the patterning, students construct their alegebraic knowledge on factoring and expanding, rather than be given a set of rules to follow

Every grade level can learn from Pascal's Triangle, and this site helps make it possible. There are explanations, examples, exercises and printable worksheets available.

This series of activities provides an introduction to some Algebra concelpts using CAS. The activities start with Algebra tiles and CAS. Patterning is modelled for the students so that they can construct the knowledge rather than be...

The calculator factors expressions by expanding and combining like terms, dividing a greatest common factor, and identifying between two squares or factorable trinomials. An example expression and quick-start guide are included.
