Product Description
This dice activity requires students to roll a die to "create" their own set of problems. The worksheet provided gives students a template to create 10 problems in which they will have to simplify square roots, rationalize the denominator and possibly use the conjugate.

Student Directions:
• For each problem, roll the dice as many times as needed to fill in the boxes with numbers. Then work the problem by simplifying the square root (if possible) and rationalizing the denominator.

Teacher Directions:
• You need one die for each student/group in your class. Every student needs to get a worksheet to do the work on.
• Collect the papers when they are done.
• You can do an effort grade (since each student/group will have a different set of answers) or you can choose one or two problems to grade for correctness. I normally take an effort grade for the grade book and then check one or two for correctness in order to give good feedback.


Helpful Hint:
• This activity will work with six-sided dice but it works even better with eight, ten or twelve-sided dice.
