With the end of today, that can mean only one thing – this Nine Weeks is coming to a close. Yes, you still have tomorrow, but we won’t be doing too much.

In Algebra II, the last full day before Spring Break was a day for simplifying radicals. This wasn’t too terrible. If you know how to make a factor tree, then you’ll be good. The thing to remember here is that “Couples go on dates, singles stay home.” If you can remember that and how to make a factor tree, you’ll be golden. See the notes for the details.

In Finite, we had a Flux Day today. You were also given an extra credit assignment that you could work on to replace the lowest homework grade. This review is completion-based because you already have the key given to you on the last page.

Well, if you are reading this, that means you survived the SAT (or you didn’t take it). If you took it, how do you feel like you did? Hopefully, y’all did well and won’t have to worry about it again.

Since the calculators were being used for testing, y’all just did a couple of Math puzzles in Algebra II. The first puzzle with Math in Movies and was a more fun activity. The second puzzle was relevant to what we were doing but pretty challenging. Did you find your way through the Radical Maze?

In Finite, we had no time for down-time. We needed to finish Section 5.4. Primarily, this involved more amortization of loans and we even made an amortization table. Then, we capped it off by looking at the present value of an annuity due. This was it for Test 3. So, while I do want you to relax over Spring Break, please study for the test that is quickly approaching on the flip-side of the break.

For many of y’all, tomorrow is a big day – it’s SAT Day. Make sure you get plenty of sleep tonight and please, please, please try your best on that test. If you can do good now, you may not have to take it again.

In Algebra II, we looked at solving radical inequalities by graphing. This really wasn’t that different from solving normal radical equations by graphing, we just had to deal with an inequality. Overall, I think it went well. See the notes for the details.

In Finite, we started the last section that Test 3 will cover. This involved calculating the present value of annuities and even looked a little (okay, fine, a lot) at loans and amortization. We didn’t finish this section, but I’d say we got about 2/3 of the way through.

Can you believe that we are almost halfway through this semester? At the end of this week, we’ll be at that point! This also means that an eligibility check is coming up. You better kick it into high gear!!!

In Algebra II, we had a last assignment that’s going on this Nine Weeks today. It really was just an extension of what we did on Friday, which meant we had an easy Monday. We were solving radical equations and only had one slightly new topic: dealing with indices. It’s really not hard. Think of it like the problem is giving you a hint “Pssst, raise each side to this power.”

In Finite, we finished looking at section 5.3 over annuities, sinking funds, and future value. It wasn’t anything really that new. We started where we left off on Friday talking about sinking funds and then finished off talking about annuities due.

Can you believe that Spring Break 2K20 is only one week away?! Where has this school year gone? …much less, this semester.

In Algebra II, we had an easy day according to most. We solved square root equations by both graphing and algebra. It was pretty easy and straightforward and sets the basis of what we will be doing on Monday with all of the different indices.

In Finite, we started looking at ordinary annuities. See the video for more details on Blackboard.

In Algebra II, we had a visit from some old friends today. The friends “a”, “h”, and “k” came back to visit us after being gone for about a month. This time, they talked all about square root functions and how they help to move the function all around the graph, just like they did for the absolute value functions. In all, I think we had a good visit. If you’d like to see all the fun we had, see the notes for the details.

In Finite, we finished looking at Compound Interest by talking about zero coupon bonds (zcb’s) and then the Annual Percent Yield (APY). Once we finished these last two topics, we looked at how to solve TVM equations using technology (aka our calculators). This will be a big component on the test, so I hope you paid attention.

The title pretty much fits the way the day went today…

In Algebra II, we took our test over Factoring, so there really isn’t anything to see here.

In Finite, we finished 5.1 over Simple Interest and Discount and started looking at 5.2 over Compound Interest. If you want more commentary than that, then see the notes below and/or the video on Blackboard.

The internet after school has been spotty, so I’m going to keep this short and sweet.

In Algebra II, we took our CBA today, which will allow me to drop your lowest test grade. Then, we reviewed for the Unit 4 test over factoring, which we will take tomorrow.

In Finite, we finished up Test 2 and then dove off into the next topic – MONEY. Today was pretty “simple” in that we started with Section 5.1 which covers Simple Interest and Discount. We didn’t finish the section, so we’ll finish tomorrow.

That’s all we have until Spring Break, and the resulting end of the nine weeks.

In Algebra II, we looked at factoring when “a” is not equal to 1. This was relatively similar to what we did on Friday, except that we had to multiply the last term by the first term. Then, we proceeded as if we were doing factoring on Friday – aka, we did the “Factor Pokey”. You know, it’s like the Hokey Pokey, but with Factoring.

In Finite, we took Test 2 today. Most of y’all finished, so tomorrow we will be starting (and maybe even finishing) Section 5.1 over Simple Interest and Discount. I’m excited about this unit!

I’m glad it’s Friday and the sun is shining…what an even bigger bonus!

In Algebra II, we looked at the first day of factoring trinomials with a=1. Some of them had GCFs we had to deal with first. It’s a little much to explain here, so see the notes for the details.

In Finite, we had our review for Test 2…STUDY!!
