I am thence behind on my Algebra two notebook. Keeping upward amongst notebooks for Algebra 1, Algebra 2, too Stats this twelvemonth is killing me. Actually, it killed me final year, too. I demand to acquire inwards the habit of gluing my notes inwards the notebook acre my students are doing the same. That only hasn't happened yet.
So, I realize I receive got a lot of notes to acquire caught upward on too postal service to this blog. But, I'm only going to jump inwards where we're at this moment. We are learning most all the things our graphing calculators tin do. First up: finding the x-intercept too y-intercept of a graph. These instructions are written for using a TI-84 because that's what I receive got a cast laid of.
As I was typing these up, I did a quick google to detect if I could detect something already typed up. Nothing looked pretty plenty to only impress too gum inwards our notebooks. But, inwards the process, I did larn a novel means of finding the y-intercept using the calculator. When I was inwards high school, my instructor taught us to ever occupation the tabular array on the estimator to detect the y-intercept. Y'all in all likelihood already know this, but you lot tin also occupation the Value Option from the Calculate menu. This was intelligence to me! I set both options downward for my students. Giving students multiple solving options is something I'm trying to create a improve chore of incorporating inwards my classes.
Another affair that throws my students off is the fact that they are rarely asked to detect the y-intercept of a graph on their end-of-instruction exam. Instead, they volition hold upward asked to detect the roots, solutions, or zeros of an equation. I actually attempt to drive dwelling family the fact that anytime they are asked for roots, solutions, or zeros, they are actually only beingness asked to detect the x-intercept.
I told my students to line a box only about this fact, star it, add together exclamation points, or anything that would acquire inwards stand upward out inwards their notes. They noted that the means I had boxed it inwards on mine looked similar the state of Oklahoma. I joked that I had done that on role because the state of Oklahoma was requiring them to know this fact.
My students actually struggled amongst the left boundary too correct boundary instructions, thence I shared amongst them a tip I learned from @druinok. She has her students house the cursor equally unopen to the cry for equally possible too thence click the left arrow a few times for left boundary too the correct arrow a few times for correct bound. My students idea this was the best fox ever. It actually cutting downward on the mistakes they were making.
If you lot intend you lot could occupation these amongst your students, I've uploaded them here.
