This is a good overall check to see how your students are doing with Data and Probability, so that you will know which skills to spend your time focusing on before testing.
See my other Test Prep items in my store. I now have one for each area of mathematics. Cheap, fast, and if you want the optional interactive SmartBoards, they are available for only $3. They are self-checking and can be used whole group, small group, or for an independent center.
