I wish parents would realize not all kids are going to get good grades. And some kids are "late bloomers".
My daughter and I are so much alike. I never gave her a hard time about her grades unless she was getting in trouble for behavioral problems. We both got C's in grade and high school, but something about going to college and studying what you really need to learn for a life ... she and I both got A's and B's in college.
Ninth Grade Algebra class,1961.Each kid had to come to the teacher's desk to get their grade.Mine was an F as was my Gen Science grade and a D in Latin.The teacher singled me out as a "prime candidate for academic probation and continuation school".Scared the crap out of me and shamed me terribly.
Parents didn't blow up at me cause they knew I was trying.I just wasn't ready to take college prep classes then.I ended up graduating from college with a B average and then got my teaching credential and Masters.
Never taught Algebra though!
