Pass out one card to each student in the class. Choose a student to start by asking "who has __________?". Then the student with the correct answer responds "I have ________, who has ________?". This continues until the first person reads his/her answer. Topics include: evaluating expression, signed numbers, combining like terms, distributive property, solving equations in one variable, absolute value, slope, slope-intercept form, and finding intercepts. There are 20 cards total. If you have more than one class, it is fun to time each class and create a competition to see which class can finish the fastest!
