This is a simple review game for teams, to review the different methods of solving two-equation systems. Directions are included on the first few slides; the activity is simple but students seemed to enjoy it. Solution methods include graphing, substitution, linear combination and matrices.
Supplies needed - Some form of wipe-off board or sheet, dry erase markers and erasers. Students could also do work on plain paper for presentation purposes.
I have adapted this activity to a variety of review topics as well.
