The Envelope Please is a math review game that can be used in any level of math class to review for an upcoming quiz or test. This is also good on days that are right before a holiday or school break. There is a complete set of directions along with a 20 questions sample game to use in an Algebra class. The sample could also be used during the first week of an Algebra 2 class or Geometry class to review some concepts previously learned. I have used this many times and the students always enjoy it.
