Flipping for Integers

Moving forward from our introductory lesson of yesterday; students practiced their ability to manipulate integers.

Here are the game procedures and rules:
Flipping for Integers

This is a two-player game that involves some luck and some strategy. The object of this game is to have a higher sum than your opponent at the end of the game.  
Materials:
1.      One Game Card per player
2.      A penny for each student
3.      A 6-sided die and an 20-sided die for each pair of student (optional 10-sided die)

Each player will take turns for a total of 10 turns to play one game. In a turn:
·        Flip the coin and roll the die.
·        The number rolled is used by the player in that turn.
·        If the coin is HEADS, then the number is POSITIVE.
·        If the coin is TAILS, then the number will be NEGATIVE.
·        The player writes the signed number in any blank on the data sheet that he or she chooses and evaluates the expression created in that row and writes the value in the third column.
 EXAMPLE: A student rolls a tail and a five, then that student has to put -5 somewhere.  
After each player has had 10 turns, they should check their arithmetic for each of the 10 sums they generated by rolling the die (and flipping the coin).
Whoever has the highest sum wins.
 ·        At the end of the playing period (Thursday's class), I will roll the 10-sided die twice. The two numbers facing up will be highlighted by the students on their game cards. Those two line items will be corrected and used to evaluate for accuracy. Since no one knows which numbers that will be, it is in the students' best interest that all answers are correct.  (Calculators are not allowed for this game.)
