A little disappointed.

I am a little disappointed in myself. Not that this isn't a great place to work but that I took myself, a lot of my Algebra 2 kids, my principle, our counselor, and another teacher to figure out that not all of my students were taught how to graph. Not only that but what a table looks like or why we have equations. I was struggling to figure out why my top students all of the sudden dropped in their grades. Now I know. Their Algebra 2 teacher never taught them how to graph or write equations let alone use a t-chart.  It was all due to the book they used. I had no idea. And because of this my top students started to hate math and doubt their skills with math and themselves. I have sense started to fix the problem but I am worried that I have done some harm to my students that might not be fixable. I had to do a lot of back teaching but I now am confident that they can recognize a table goes with at graph, equation and word problem and what a benefit it is to know the difference between them all. I was scared when they only new how to play around with an equation. Now they are having a better time with tables and using tables and graphs together and switching things around. The writing of equations is a little tricky to them but every day I am coming up with new problems in the world where they can write equations and equations that they can write word problems with. I just wish that I had caught it earlier.
