Web Resource Review #2: Algebra vs. the Cockroaches

For my second web resource review, I would like to mention the site for the game Algebra vs. the Cockroaches.  This is a wonderful resource for Algebra I teachers.  I recently played this game with my classes and it was a huge success.  The game starts with one roach running along a line on the coordinate plane.  The object of the game is to kill the roach(es) by identifying the equation of the line that the roach(es) are running along.  As time goes by, the roaches multiply (all running along the same line).  If you get more than 15 roaches on the line, the game is over and the cockroaches win.  I played this game with high school freshman.  At first they thought that the game was lame and cheesy.  However, by the end of the game, they were really into it and wanted to play again.  I would highly recommend this site to any Algebra I teacher.  It assesses the skills of identifying the slope from a graph, identifying the y-intercept from a graph, and writing an equation in slope-intercept form.  These are all essential skills of Algebra I.  This is also a game that students can play at home, on their own, to practice these skills.
