This week was an odd week for me. The things we reviewed and learned new tricks for were in the last few chapters of Algebra II. I remember feeling confident in class and going home to do homework and totally having to reteach myself from the text book. Then on a test I’d get all mixed up between the way Mrs. Angie taught us and how I had taught myself. The first two days or so I found myself in the same position. This made me really nervous for what is to come this year. However in class I began writing exactly word for word what Mrs. Robinson said for each step and I discovered this helped a lot because I have a very auditory memory. So seeing what she had said for each step (even if it was just “add”) helped me to practice and study for the test.
Speaking of the test I was really excited to see how much I retained. I was especially happy to see that I memorized all the steps for graphing a parabola since I had trouble figuring everything out with this last year. I also was happy to see that even though I had trouble on the summer packet, by figuring out a way to retain the things I learned in class I was able to do problems similar to those that confused me on the summer packet.
Now the less optimistic side..
Although I learned all the steps for graphing a parabola on the test I had trouble with problem #12 letter G. The actual graphing of the parabola messed me up. The fact that the parabola opened down threw me off I guess.. I got A-E correct, but I think because I got letter F wrong I was unable to graph the parabola. For letter F I did -(-2)squared+2 (-2)= (-2,-8)
I know the -2 was wrong but I don’t know what should have been plugged in instead. If someone could help me with letter F and then maybe show me at school how to graph the parabola that would be amazing.

Taylor,
ReplyDeleteGreat job on reflecting where your confusion was. It can be confusing when something can be done multiple ways. Be sure that you explain how to do a concept next time. For example work through a parabola problem or re-explain the steps in your own words. It is very helpful to know that you are an auditory learner. I will keep that in mind as I plan activities.

ReplyDeleteFor #12 on the test letter F your vertex will be (1,1). You find this by letting your axis of symmetry (x=1) be your x. Then just plug the axis of symmetry into the original quadratic. You will get -(1)squared+2(1)=1. And that's your y to give you the vertex (1,1).
