Is it cold enough for you, yet? I’m not sure how y’all feel but when I feel icicles growing off my nose when I walk outside, that’s pretty cold! At least it’s nice and toasty in the classroom, where learning can still take place.
In Algebra II, we looked at how to solve square root inequalities by graphing. This was pretty straight-forward if you understood how to graph square root functions. The only tricky part was understanding how to write the inequality. See the notes for the details.
In Geometry, we had a fun/easy day on the calculators. As such, nothing much was missed here.

Assignment – Day 4A – Solving Square Root Inequalities
Have you ever been excited and wanted time to speed up but at the same time want time to slow down because there is so much that needs to be done by a certain date/time? That’s exactly how I’m feeling this week. Nonetheless, time keeps moving forward whether we want it to or not, so I guess it’s time to “Suck it up, buttercup.”
In Algebra II, we looked at More Radical Equations and Applications today. This was basically an extension of what we did on Friday with one little new nugget of information – the index. Simply put, the index of the radical tells us how many roots we are taking. For example, if the index was 3, we would be taking the 3rd (cube) root. So, to undo this algebraically, we would need to raise both sides to the 3rd power.
In Geometry, we had a day to just practice a lot of what we have covered thus far. This was a good time to put everything together and get used to just pulling seemingly random stuff about triangles together into one assignment. Overall, I think it was a good lesson that may have knocked off a few cobwebs.
Can you believe that we are only one week away from Spring Break?! Just for that, I say we have easy lessons today!
In Algebra II, we looked at solving radical equations. We looked at doing these both graphically and algebraically. I think across the board, all classes felt this was pretty easy and straight-forward, as evidenced by the number of assignments that got turned in today.
In Geometry, we looked at different segments within triangles. These segments included perpendicular bisectors, angle bisectors, medians, and altitudes. They are a little hard to explain just typing, so see the notes for the details.
Have a great, safe weekend and remember to not do anything I wouldn’t do!
Because he was never RIGHT! …#BadMathJokes
For real, though, math is on of the punniest languages that exists. You can just rip a pun and it’s awesome…at least if you get them. Anyways, let’s get down to business (to defeat the Huns!)
In Algebra II, we started our next unit over Radicals. I’m not sure if it was the weather or what, but I was hoping this radicals unit would be “radically” awesome, but no one seemed to have fun today. But, I sure did! We learned how to graph square root functions using the infamous a, h, and k transformations that we were introduced to in Unit 1. I told y’all they would be our best friends and they have yet to disappoint…I promise there will be more of them to come in the future, too!
In Geometry, we look at ratios. This started out simple with cross-multiplying proportions, finding slope, etc. Then, we stayed simple, but started looking at ratios as they relate to similar geometric figures. The main figure we were interested in was the triangle, but we had to include everyone to be fair, so we did! See the notes for the deets!
Keep holding on, because you’ve almost made it to Spring Break 2019!! We just have a short week and a half until we get a break.
In Algebra II, we tested over factoring. Tomorrow, we will start a new unit on Radicals. It will be a “radically” awesome time, dude!
In Geometry, we looked at, for the second day, shortcuts to proving triangles are congruent. These shortcuts are as follows:
- SSS (Side-Side-Side)
- SAS (Side-Angle-Side)
- ASA (Angle-Side-Angle)
- AAS (Angle-Angle-Side)
- HL (Hypotenuse-Leg)
Make sure to look at the notes for the details!

That’s what we keep doing it seems – rolling rolling rolling along. We are already almost done with the 1st half of the course, meaning that it is almost report card time, so don’t get caught with your grades down!
In Algebra II, we finished the last topic in our factoring unit. This involved factoring higher order polynomials, i.e. x^3 and higher. We saw that there are two methods to do this with details of both in the notes:
- Factor by grouping
- Factor using Synthetic Division
In Geometry, we looked at proving triangle congruence. This meant showing all three sides and all three angles are congruent. It was a tedious process, but nonetheless we pushed through. Now, tomorrow, we will get to use some shortcuts!
The day we’ve waited all week for is finally upon us…Friday! While we may have been antsy for the weekend, the learning must continue.
In Algebra II, we looked at what happens when there is something other than a 1 in front of the x^2 that we cannot factor out. We were able to factor the trinomial, however, but we had to use something called “Factor by Grouping”. This is difficult to explain here, so see the notes.
In Geometry, we dove deeper into isosceles and equilateral triangles. Again, there’s not too much to say here, so see these notes as well.
Come back on another day! I don’t know about you, but with all this rain, I have been very sleepy as of lately. That’s why I’m ready for it to quit raining and for the sun to start shining again. Nonetheless, the show must go on.
In Algebra II, we looked at factoring trinomials of the form ax^2+bx+c where a = 1 and/or we have a GCF that we can take out first and then a = 1. This is in order to set up what we will see tomorrow, where a > 1. Stay Tuned!
In Geometry, we started looking at our triangles unit. This was done by first classifying the triangles and then we looked at a few theorems. It was a longer lesson, but I hope it wasn’t too painful.
I hope everyone enjoyed their three-day weekend! I had quite a busy one, as I went out of town for my brother’s wedding, but nonetheless, it was a great one.
Now that we are back until Spring Break, Algebra II looked at Factoring Special Cases. Just to drive them home, we will look at them again tomorrow. There are three of these cases:
- Difference of Squares
- Difference of Cubes
- Sum of Cubes
In Geometry, we had a little fun today. That’s because we were able to play with the Rovers and program the calculators to make them drive somewhere. This used conditional statements and our knowledge of angles to program and draw a simple angle and then a linear pair. I think I can speak for everyone and say we had so much fun that we want to do it again.
