Test Review Game Get into your groups. With a red pen, check all your answers until you have arrived at a conclusion as a group. Every person in the group should understand how to do each problem. Once you have had time to accomplish this, I will call on random students to answer the question. They must come to the board and explain the solution. If you get the problem correct, your team gains 2 points. If you get the problem wrong, your team looses 2 points. At the end of the review, the team with the most points wins. And yes, there is a prize 

Key Concepts to Know To add integers with the same sign, add their absolute value. The sum is: Positive if both integers are positive Negative if both integers are negative To add integers with different signs, subtract their absolute values. The sum is: Positive if the positive integer’s absolute value is greater Negative if the negative integer’s absolute value is greater The sum of any number and its additive inverse is zero. To subtract an integer, add its additive inverse The product of two integers with different signs is negative. The product of two integers with the same sign is positive. The quotient of two integers with different signs is negative. The quotient of two integers with the same sign is positive.
