AP Statistics Assignment for 11/29

By now, you should have settled on a mid-year project idea and have gotten started on the Project Proposal Form found in the Google Drive folder here. This proposal will be due at the start of class tomorrow, so work with your group and finish it tonight! When you submit the proposal, please make sure that you names appear in the filename.

And if you haven’t finished the textbook review assignment—1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41 from pages 331-336—you should do that tonight as well.

Intermediate Algebra 2 Assignment for 11/28

We will have our first quiz on Unit 3 tomorrow, all about graphing and identifying key features of parabolas. Finish HW 3.7 – Parabolas Quiz Review for a homework credit (you can find the answers to it here).

I’d also recommend that you continue to work on the IXL modules below. Many of you still haven’t gotten them up to the expected scores!

Intermediate Algebra 2 Assignment for 11/27

We will have a quiz on the first part of Unit 3 on Wednesday, November 29. It will cover all of the work about parabolas that we have done, including today: Finding key features with the calculator. The notes from today can be found here, and your homework is HW 3.6. If you need a refresher on using your calculator, check out the video here (it uses a non-parabola graph, but the commands are the same).

Fractals & Chaos Assignment for 11/27

We explored the behavior of the Logistic Population formula some more and formulated a few questions:

  1. The end behavior of iterations is a single fixed point up to a = 3.0, and at a = 3.1, the population has bifurcated into a two-cycle. Question 1: At what value of a does this bifurcation actually happen?
  2. There is a two-cycle up until a = 3.4, with a four-cycle at a = 3.5. Question 2: Do both points of the two-cycle bifurcate simultaneously, or does one split before the other? In other words, can you find a three-cycle between a = 3.4 and a = 3.5?
  3. After a = 3.6, we observe bands of chaos. Question 3: Once chaos appears, is that it? Or is there something to be found between bands of chaos?

Update: You will be permitted use of your notes (but only your notes, no textbook) on tomorrow’s investigative task.

Today, we start our Mid Year Group Projects by forming groups of 2-3 and starting to think about ideas. We’ll be spending most of the time before winter break working on this projects, and this project will be a major portion of your second marking period grade. Information about projects, including general information about expectations for the project, a description of expectations for the written report, the project proposal form, and a schedule for December can be found here.  Note that the first due date is Thursday, November 30th. For now, keep thinking about project ideas!

Your test will be on Friday, December 1st.  We’ll spend most of Thursday reviewing any questions you have from the review: 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, 41 from pages 331-336 in the textbook, which you should complete by then.

Finally, remember that tomorrow we will be doing our Chapter 12 Investigative Task in class.

Intermediate Algebra 2 Assignment for 11/21

We did some IXL practice in class today while I met with students individually. Whatever modules you didn’t finish in class are due on Monday (for a separate HW credit each!)

 

AP Statistics Assignment for 11/21

We didn’t quite finish reviewing the Chubby Dogs experiment, so you can find my answers here.

Next week is going to be an important one for us. Here’s what’s in store:

  • On Tuesday, we’ll be completing an Investigative Task for Chapter 12. It will be an in-class task, assigned and due within the class period. Please do not be absent on Tuesday.
  • On Friday, we’ll be taking out Unit 3 test, so while the review assignment won’t be due until Thursday, you may want to get started on it now: from pages 331-336, 1, 3, 7, 9, 11, 15, 19, 20, 23, 29, 32, 40, and 41.
  • On Monday, we’ll be starting on our midterm projects. More details about the project will be discussed on Monday, but you should get started thinking about ideas you’d like to investigate. Listen to the Freakonomics or Hidden Brain podcasts for some inspiration, or rewatch some episodes of Mythbusters (or check out the archive here). You will be working in groups of 2-3 for this project, no individual projects allowed without very special permission!

Intermediate Algebra 2 Assignment for 11/20

The parabolas we’ve been working with in class so far are graphs of quadratic equations, of the form f(x) = ax^2 + bx + c. Today, we practiced using graphing technology (either your graphing calculator or http://www.desmos.com/calculator) to graph parabolas and identify the key features. You can find the notes here, and your homework is HW 3.4 – Graphing Parabolas.

Finish question 5 from Iterated Functions, using the apps on MathInsight.org. Note that all of these functions have fixed points at zero, where the instantaneous slope at zero is equal to 1. This creates some interesting behavior for some fixed points, so make sure you check the behavior of seeds on either side of the fixed point.

Intermediate Algebra 2 Assignment for 11/17

We explored parabolas some more with yet another Desmos activity today, formalizing our vocabulary for the key features of the graph. You can find the notes uploaded here, and the homework for the weekend is some practice at identifying these key features: HW 3.3 – Parabola Key Feature Vocabulary.

Intermediate Algebra 2 Assignment for 11/15

We started unit 3 with a Desmos activity, and your homework tonight is to reflect on what happened. Please consider the following two questions:

  1. Describe one thing that you learned from the Will It Hit the Hoop Desmos activity from class?
  2. What else do you think you could use a parabola to model the shape/path of?

I’ll be collecting your answers to these in class tomorrow, as well as asking you to share them with the class.
