This is the last you’ll hear of me for the 2018-2019 school year! We had our final review today for Algebra II and that’s it!
Regardless of the outcome, know that I’ve enjoyed having each and every one of you this semester and school year for that matter. If you ever need any help, advice, or just need a quiet place before/after school to work on stuff, my door is open.
Study hard, it’s almost SUMMER!
Algebra II Final Review – Final Exam Review
Now that our last Monday of the 2019-2020 school year is complete, we have only 3 more days left, or if you want to be exact – 2.53 days. But, I don’t know about you, but if I have to wake up and come in at 8:10, then I call it a whole day. Anyways, it’s review time!
In Algebra II, we worked independently on the review today for some extra credit points towards our final exam. No answers were given out, so check back tomorrow for the filled-in review, which IS a grade.
In Geometry, we worked on the Day One review and did that together. As such, it was turned in for a grade and can be seen by clicking the link below. This means your extra credit opportunity will come tomorrow when you work on the Day Two review independently.
Final Exam Review Day One – FILLED IN
Yep, you read that right! We have just completed the last lesson for the 2018-2019 school year. Unless you consider a review (or two) a lesson, then we aren’t done yet.
In Algebra II, this last lesson involved looking at applications of rational expressions and a few “complicated” rationals equations. They weren’t really that bad, but we did have to reach back and remember what it meant to have a least common multiple. Then, in the word problems (a.k.a. the applications), we had a little visit from the subject called Physics. Hopefully now you can see just how related Math and Science really can be in the real world.
In Geometry, this last lesson involved Geometric Probability. This basically involved probability used different geometric shapes. Whether it’s a circle, a triangle, a line segment, etc., we can use geometric probability to help us figure out our chances of landing in a certain area.
It’s concert season here at LHS! I’ve already seen one Spring program (I’m talking about you, Panther Pride). Now, we have the Band concert tonight, where you can bet I will be in attendance. But, with all this excitement, let’s not forget about the academic side of school!
In Algebra II, we looked at solving rational equations. As with most of this unit, we’ve pretty much all done this before, we just didn’t call it as such. After all, the key point here is that we have to cross multiply and then solve for “x”. But, even after we get a solution, you have to proceed with caution because these solutions can be tricky and extraneous. What’s extraneous, you ask? It’s where we appear to have a solution, but in reality, the solution is bad. For example, if one of our solutions causes the denominator to be zero, then it’s a “no go” (a.k.a extraneous) solution.
In Geometry, we didn’t really do anything too terribly new. We just had to decide today how to count the different outcomes. Is it a combination, permutation, or neither? The way to remember the answer to this question is that if order matters and we do not replace the items (once it’s picked, that’s it), then we have a permutation. If order does NOT matter and we do not replace the items, then it is a combination. If neither of those fit, then we have to use our “plain Jane” counting techniques.
I mean, this year is almost over, yet didn’t we just begin? Same thing with this day to! I’ve got to run, so see the notes for the deets.
At the rate it’s been raining here lately, we may as well start building docks over the parking lot because before too long, we will need to start driving boats everywhere. It’s a good thing that there are only 2 weeks left, maybe we won’t have to resort that that after all!
In Algebra II, we looked at multiplying and dividing rational expressions. Multiplying was pretty straightforward – you just multiply and then reduce like how we did yesterday. Division was a little tricky though. However, KFC …er I mean KCF came in clutch. The thing to remember when dividing is:
- Keep the first expression.
- Change the division sign to a multiplication sign.
- Flip the second expression.
Now if we just had some chicken to go along with it, we’d be perfect!
In Geometry, we look at permutations. The thing to remember here is that when deciding if you need to use a permutation, ORDER MATTERS and we will DRAW WITHOUT REPLACEMENT. If these two things hold, then we can use permutations. That’s the main thing for today, so see the notes for the details.
Today was the last day of STAAR testing! I know everyone is just as relieved as I am and I didn’t even have to take the test.
In Algebra II, we looking at how to simplify rational expressions. This was pretty straightforward, as we were just trying to find what we can cancel out on both the top and the bottom. However, just because we were able to cancel it out does not mean that we can get rid of it. Graphically, that piece is considered a hole in the graph. Luckily we didn’t have to do too many graphs today because by the time you throw in the asymptotes AND the hole, it get’s to be a little busy.
In Geometry, the other teachers’ classes were taking the Biology STAAR test. As such, they didn’t do much today, so neither did we. Free Day for the win!

It’s raining cats and dogs outside (or at least that’s how bad it sounds)! I hope everyone stays safe and dry!
The internet is spotty, so I’ll keep it short today. In Algebra II, we had a free day since most were testing, but in Geometry, we learned about Sample Spaces. See the notes for the details.

Many of you that are in my class will be taking the U.S. History STAAR test tomorrow. I hope y’all knock it out of the park!
In Algebra II, we looked at how to find asymptotes algebraically. For the vertical asymptote(s), this was pretty easy because it occurs when the denominator is equal to zero. This usually involves factoring the polynomials to easily see where this occurs. For horizontal asymptotes, we have three rules:
- If the top degree > bottom degree, we have no horizontal asymptote.
- If the top degree < bottom degree, we have a horizontal asymptote at y = 0.
- If the top degree = bottom degree, our horizontal asymptote is a ratio of the leading coefficients.
In Geometry, we simply worked on the Transformations assignment, which is based on the notes that we did yesterday.

Okay, well maybe it’s “Sith”, but today is May 6th, so it fits.
In Algebra II, we started our new unit over Rationals. But, though it’s a new unit, it’s still time to get excited because IT’S OUR LAST UNIT!!! We had a visit from our old friends a, h, and k and they helped us to graph rational functions. Now, these are the basic functions. Tomorrow, we get more advanced. But, let’s take the easy stuff while we can.
In Geometry, I can’t say we’ve started the last unit, but we did look at the topic of Transformations today. This won’t be anything that will be tested, but it was covered nonetheless. It’s something easy to do without a calculator and while they are using our calculators for STAAR, it fits the situation.
