Reflection: Complex Tasks Multiplying Radical Expressions - Section 3: Exit slip


Have you ever created a problem, and it turns out messier than you intended?  Thanks to feedback from a fellow teacher, I am realizing that for the Exit Slip in this problem.  It is not an impossible problem, but it is an extremely messy problem.  After subtracting the square root of seven from 12 square root of three and dividing it by two, the result is a binomial with radicals.  To find the height of the triangle, using the Pythagorean Theorem, students need to square the binomial.  Here is the key to the problem, but should possibly only be given to your higher level students. 

Here is an easier Exit slip in the shape of a Pentagon.  Therefore the two shapes to find the area will be a rectangle and a triangle only.
