The instructions for today’s activity can be found here.
Your test on Unit 8 will be on Tuesday, April 24th. We will spend tomorrow (Friday) and Monday reviewing for this test. Tonight for homework, choose any two of the IXL modules posted below and get your score up to at least an 80.
Remember: your IXL username is your first initial and your last name, followed by “1@ithaca” and your password is “abc123” (some of you have a slightly different username, please email me or post here if you have trouble logging in).
We did some more practice with the Law of Cosines today. Tomorrow and Wednesday will be a review of both Law of Sines and Law of Cosines, in preparation for our Unit 7 test on Thursday, March 22
Do some more exercises from chapter 21: pages 558-559, 19, 21, 24
Also, you should get started on the review assignment for this unit in preparation for our Unit 5 test on Monday the 12th. Read over the summary of the unit on page 562, then from pages 562-568 do exercises 5, 6, 11, 12, 18, 30, 31, 37.
Finish reading chapter 19, pages 500-510.
From pages 512-513, do exercises 7, 9, 12, 13.
Finally, I want to give a test on chapters 17-19. Unfortunately, due to last Wednesday’s snow day and some other delays we’ve experienced, we will have to schedule this test for Monday, February 26 (the day we get back from break). It’s not ideal, I acknowledge, but it’s our reality. We’ll spend some time reviewing these three chapters on Thursday/Friday and I’ll have some additional practice material to distribute.
Our test for Unit 4 will take place on Wednesday, January 31st. By Monday, you should complete the textbook review assignment: pages 434-438: 5, 16, 20, 21, 23, 25, 27, 28, 37.
If you’d like to review my answers to the Chapter 16 worksheet from class today, you can find them here.
Homework: Read pages 423-429 (finishing Chapter 16), then do 26, 32, 33 from the exercises.
Also, we’ll be having our Unit 4 test after exams (sometime the week after, probably January 31st or February 1st). You should start looking at the review assignment: pages 434-438: 5, 16, 20, 21, 23, 25, 27, 28, 37.
Our test on Unit 4 will be on Friday, January 19th. Please do not be absent on that day! If you know for some reason that you will be absent on that day, please arrange a time before the 19th to take the test! Otherwise, we will have to schedule a time for you to take the test during exam week!
Our last “new” topic from Unit 4 was a revisitation to the solving of quadratic equations. Recall that the decision to permit the square root of negative numbers was motivated partly by allowing all quadratic equations to have solutions, so today we spent some time talking about how to write/solve these equations. Your homework is HW 4.13 – Solving Quadratics with Nonreal Roots. You can find the notes here and some more examples in this video.
Cumulative IXL Review Modules (newly added modules are in bold)
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!
Finish reading chapter 9, pages 242-246, and do exercises 18, 19, and 30 from pages 251-254.
We will have our second Unit test on Tuesday, October 31st (sorry). In preparation for this, I recommend you work on the following review assignment: from pages 257-261, exercises 10, 11, 16, 19, 20, 22, 23, 30 (and read page 255 for good summary of the unit).
Read pages 114-121, up to the section about “Z in reverse.”
From pages 132-133, do exercises 15, 18, 20, 22, 23, 26.
Finally, LET IT BE KNOWN that your first test in Statistics will be on Friday, September 29
