## Reflection: Routines and Procedures Polynomial Functions Review Day 1 - Section 1: Warm up and Homework Review

Both the SBAC and the PARCC Common Core assessments will include problems centering on Math Practice 3 (Construct viable arguments and critique the reasoning of others).  This has been a major focus for me this year as my students have not had a lot of experience either explaining their own processes or evaluating someone else’s.  One of my favorite ways to do this is with a warm up where I give them a problem with (or occasionally without) a mistake that they have to find and correct like Warm Up 1.  In today’s problem, I gave them some zeros which had been used to write a polynomial equation.  The mistake was that the zeros like 1 were made into the binomial factor “x+1” and should have been made into “x-1”.

So many of my students looked at this problem and agreed with it because the rest of the work was done accurately  like Warm Up 2.  I have to say I was surprised by the number of students that were tricked.  One of my favorite methods of dealing with a situation like this is to laugh evilly and tell them all that I tricked them.  This lets them know that they made a mistake in a humorous way and also encourages them to fix it.  Humor is definitely one of my favorite classroom management strategies.
