# Featured Game:   Face Off!

Students place markers on the numbers 2-12.   Students toss two 6-sided dice, find the sum and remove a marker from that number, if there is still one.   The first player to remove all markers wins the game.   This game can be used as addition practice or as an introduction to the probability of the different outcomes of rolling two dice.   This game was developed by a Monmouth University student for the Probability Fair.

# Three Strikes and You're Out! Game

Students need lots of practice to learn and master basic facts. Games are a fun way to provide regular practice and they can be easily differentiated to accommodate the varied needs of students in a class. The Three Strikes And You're Out! game is designed to practice addition or subtraction facts.

The game uses the sum of two dice to practice addition facts, but may easily be adapted to practice subtraction facts by using two 12-sided dice and finding the difference. The game handouts include directions, variations in play and scoring, game boards for both the addition and subtraction games, as well as game pieces that may be used to support the baseball theme.
