Do you ever feel like there are not enough hours in the day to get everything done? Good. That means I’m not alone in this thought.
Anyways, in Geometry, we looked at properties of angle bisectors, perpendicular bisectors, altitudes, and medians. It was pretty straight-forward and I’m running short on time, so see the notes for the details.
In Algebra II, we took a CBA, which will allow me to drop your lowest test grade. Then, we worked on the review for tomorrow’s test. That’s right, we have a TEST TOMORROW! STUDY!
The hallways are a jinglin’ and the Panther senses are a tinglin’. That can only mean one thing – It’s Homecoming! Tonight those bulldogs from Waller won’t know what hit them when we dominate. But before all of the festivities of tonight, we have some learning to get accomplished in the classroom.
In Geometry, we focused on ratios and talked about how these help us determine if two shapes are similar. For the most part, this was a large review, as we mostly dealt with slope and proportions. The only new part is that we applied the ratios to similar polygons. It’s really that simple! Must be nice for a Friday!
In Algebra II, we did the last day of our factoring unit. This involved looking at how to factor higher order polynomials, which are those that are raised to the third and higher powers. There were two methods to do this: Grouping or Synthetic Division. Grouping was like what we’ve been doing and we used our calculators to help us with the synthetic division. Since this is the last of the material, we have to start preparing for a test early next week.
How was everyone’s first Advisory period today? Did you learn any cool tips about how to increase your productivity both while at school and at home? How will you apply those? Speaking of being productive, let’s see what we did in Math today!
In Geometry, we looked at Congruence shortcuts for the second time today. Today’s emphasis was on identifying the parts of the triangle that were congruent and then writing the congruence statements. Remember, we CANNOT assume anything that isn’t given or a known fact. Also, corresponding parts must stay together!
In Algebra II, we looked at factoring trinomials with a GCF and/or a ≥ 1. If a > 1, we only had one additional step from Tuesday. Other than that, the other steps were the exact same. This step involved multiplying the “a” times the “c”. That is, if your trinomial was in the standard form of ax²+bx+c and a>1, then we had to find the factors of a*c. Other than that, it was the same.
It’s Hump Day! What what! For students, this also means it’s an early release day. Enjoy your 1/2 day off!
In Geometry, we just did a quick, 10-question CBA. So, nothing to see here today.
In Algebra II, we had a second day of Factoring Special Case Polynomials. There was no true lesson today, but I did work four problems on the assignment. Thus, they are posted below.
Usually, when planning for time, we don’t factor in shortcuts and that’s a good thing! But, when one class talks about factoring and the other about shortcuts, then I suppose it’s time to factor in shortcuts.
In Geometry, we learned about congruence shortcuts. These shortcuts help us to show triangles are congruent without showing all six corresponding parts are congruent. Actually, we only need three parts but in certain cases. These cases involve SSS, SAS, ASA, AAS, and HL. For what these stand for and more, see the notes.
In Algebra II, we looked at factoring trinomials where a=1. This meant that either “a” was already equal to 1 or we had to factor out a GCF first and then factor the remaining trinomial. It’s kinda hard to explain here, so see the notes for the details.
We’ve got spirit, yes we do! We’ve got spirit, how ’bout you? Happy Homecoming Week, Panthers!
In Geometry, we looked at corresponding angles and sides as well as using those sides and angles to prove triangles are congruent to one another. This was a bit painful, if I’m being honest, because no one like proofs. However, we survived. The key thing to remember is that you have to show all sides and all angles are congruent using properties and theorems that we’ve discussed thus far. Then, once all corresponding pieces are proven congruent, we can conclude that the triangles are congruent. Tomorrow, I’ll teach y’all some shortcuts, but *sssshhhh* it’s a secret. 😉
In Algebra II, we looked at how to factor special case polynomials. These started out simple enough in the case of the difference of squares. However, when we looked at both the sum of cubes and difference of cubes, things started getting a little messy. There will be formulas on a formula chart for you to use on the test. So, if you don’t have today’s formulas memorized, then no worries. Notice that I have no mention of a sum of squares, that’s because these are prime!
With the bell at 3:45, we saw the end of the first six weeks of school! This means that you are now 1/3 of the way through your Math course, as both Algebra II and Geometry are only a semester long. There’s no time to dilly-dally around. Make sure your grades are in check.
In Geometry, we had a lesson on isosceles and equilateral triangles. The lesson was pretty short, but it’s hard to put into words to type (or maybe I’m just tired and want to go home). See the notes for the details.
In Algebra II, we starting Unit 4, which will be over factoring. This was kicked off by looking at factoring the greatest common factor. Basically, we are looking for the largest factor that we can divide out of ALL terms. That’s really all there was to this lesson. So, see the notes for several examples.
Have a great, safe weekend!
If you were the one asking and asking for rain, you can stop asking now. Please, I’m begging you down on my hands and knees, stop asking for it to rain! I realize we aren’t getting the devastating flooding that Houston and Beaumont are getting, but still.
Anyways, Algebra II tested today over Polynomials. So, there’s not much to say about that.
In Geometry, we started what will be about a month’s worth of triangles today. In this first lesson, we classified triangles by their angles (acute, equiangular, right, and obtuse) and their sides (scalene, isosceles, and equilateral). We also learned a few different corollaries and theorems to help us out. It felt like a “data dump” today, but hopefully this will all become clearer in the next week or two.
That was the general consensus today between both classes. It’s time for another test already?! Yep, it is!
In Geometry, we worked on the review. So, make sure you are studying it tonight!
In Algebra II, we looked at dividing polynomials using synthetic division. This was our last topic of the Polynomials unit. This means that we will have a review tomorrow with a test on Thursday. Hopefully today’s lesson wasn’t too painful!
UIL eligibility is coming up quickly! This Friday is the first eligibility check, so make sure you are staying on top of your grades!
In Geometry, we had a practice day over everything we’ve done in Unit 3. This involves conditional statements (and their variants) and parallel lines. Make sure you know this material because we have a test coming up on Wednesday!
In Algebra II, we looked at dividing polynomials using long division. This can be tedious, but I hope that the process we used today helped to make sense of the concept. This is one of two ways that we will learn to divide polynomials. We will learn the other method tomorrow. Be sure to stay tuned!
