S.B.
As a former middle school math teacher, I would not go in assuming that the teacher is irritated with your child. IF in fact your child is not paying attention, then he may be irritated with his behavior. He may also know that your son has the capability to perform better. It may be irritation or disappointment at the situation, not necessarily at your child. The meeting will be more productive if everyone goes in open and willing to hear each other out.
That being said,,,the report card should be the FINAL phase of communication. The teacher should have known there was an issue much earlier in the grading period and you should have been contacted MUCH earlier. What is the cause of the F? Lack of completed work? Poor test grades?? In the age of cell phones and email, there is no excuse for not talking to you sooner.
And please don't let the teacher fall back on the excuse of "I was trying to teach your child responsibility" when you talk about the lack of communication. A teacher's job is NOT to teach responsibility, That may be a bi-product of what we do, but it is not our job. No where in any curriculum, regardless of the state, will you see "teach responsibility" listed.
I would also want to know what the teacher is doing to correct the behavior he is complaining about. Is he redirecting your son or sending him to the hall ? Because is the hall he will just get further behind - he's missing out on valuable class time and only getting more overwhelmed. (If this is his first year in middle school , that can be a HUGE transition for many. Behaviors you have never seen or heard about before may show up in class. )
I would want to know what services are available...does the teacher offer tutoring or extra help? If it's a matter of work not being completed, can the work be made up and the grade retroactively changed (possible, but unlikely). If it's testing, can he redo failing tests for a higher grade? (My students were able to raise any grade less than a 70 to a 70 if they came in for a tutorial about the test and did a retake).
And what is the teacher willing to do to open the lines of communication? Communicate via email, writing in a planner. Whatever the plan is, make sure it is written communication to document everything.
Not every teacher and student are going to "click". Just like any job, there will be personality conflicts. Hopefully, the teacher and your son will learn to work together.
One more thing, I would request an administrator be present. This will be a third party to "witness" the meeting. It will be someone higher up that you can call on for assistance...someone to report to if you feel like your child's needs aren't being met. An administrator will also be good to have around should the teacher do something upsetting to you.
GL!
