The scoring rubric for the Algebra Sampler question 39 gives a good recap of trial and error and checks needed for full or partial credit [4] answers 6 and 2, and appropriate work is shown, such as an algebraic solution or trial and error with at least three trials and appropriate checks.
or
[2] The trialanderror method is used to find at least one solution, but only two trials and appropriate checks are shown.
or
[2] The trialanderror method is attempted and at least six systematic trials and appropriate checks are shown, but no solution is found.

Does anyone know what the regualtions are for guessing and checking on the upcoming Integrated Algebra Regents exam (for problems that do not say solve algebraically)? In speaking to some colleagues, some thought the necessary number of tries for full credit was going up to 5 and someone else thought the method might not be allowed at all. Anyone know the answer to this? Therese G (NYS Goddess of Algebra)any idea? Dave Ryley Beacon HS
