The computer assignments will be done using the web-based MathXL software.  The program recognizes common student errors and provides problem specific, step-by-step feedback.  The problem types are the same each time but the numbers are algorithmically generated so the problems can be repeated any number of times for practice.  There are sample problems and guided solutions to problems. 

There is a "Getting Started with MathXL" pamphlet and a "How to Enter Answers" tip card enclosed with the MathXL code.  Click here if you need a copy of the "How to Enter Answers" card.  There is also a very good tour of MathXL at http://media.pearsoncmg.com/aw/aw_mml_shared_1/player_tour/producttourmxl.html .
