I'm working on an alternative certification program to become certified as a teacher in the state of Texas - specifically high school math. As part of my certification, I have to take a content exam to prove I can teach math; so, I've been brushing up on my math knowledge.
My degree is in math; but, it's been many many moons since I've worked with polynomials or factored a quadratic equation. Dang! That stuff's hard! And I haven't even looked at pre-calc or calculus yet.
I'm allowed to use a calculator in the exam; so, I bought a TI-84 Plus Silver Edition (which is on the 'approved' list). I was intrigued by the TI-Nspire CAS; however, I settled on the TI-84 because it's very similar to the TI-83 which is the defacto standard for high schools around these parts. Learning all of the ins and outs of the TI-84 is proving to be just as daunting as refreshing my math knowledge.
Right now, I've feeling very stupid.
But, I'm going to persevere.
Maybe I should get the pink faceplate for my TI-84
