Chapter 15: Probability Rules! (Days 140-141)

Today in Ethnostats, we work in Chapter 15, on rules of probability. The students learn an addition rule where the events need not be disjoint, and a multiplication rule where the events need not be independent.

In my last post, I wrote that I would give a 12-point assignment today. I end up assigning the questions at the end of the chapter, even though the Chapter 15 quiz is several weeks away. The students must answer the first 12 questions on that page -- in other words, it's a dozen questions for a dozen points.

One of these questions asks about probability using playing cards. I've been meaning to give the students a playing card worksheet, and so I finally do this today. The students glue this into page 28 of their Stats Scrapbooks -- and as it turns out, the 12-point assignment happens to be Assignment #28. So the next few interactive notebook pages and assignment numbers will line up.

Meanwhile, in Calculus yesterday, we moved on to Section 6.5, on average value of a function. We skipped over 6.4 on arc length (definitely not on the Calculus AB exam) in order to reach 6.5 (definitely on the Calc AB exam). And in Trig, we proceeded with Section 3.5 on angular velocity.

Next week will be chapter tests in Calculus and Trig -- Chapter 6 in Calc, Chapter 3 in Trig. I haven't quite decided what the Calculus test will look like yet, but as we get closer to the AP, I need to get closer and closer to AP test conditions. This means that there'll be sections for multiple choice and free response.

Today is Sixday on the Eleven Calendar:

Resolution #6: We follow directions and participate in class.

From completing the playing card activity in the interactive notebooks to answering questions while taking notes, the students have numerous opportunities to follow directions and participate today.

In my last post, I mentioned that many of my students are on our school's lacrosse team -- and the lacrosse referees are now officially on strike. This was a sore subject with the players in my class -- they didn't want to talk about it at all, especially since we were favored to win the next two games.

I know that I'm not supposed to compare lacrosse in 2022 to Track in the COVID-93 or COVID-96 worlds, but the whole purpose of the What Ifs? is more me to put myself in my students' shoes. Well, suppose that in COVID-96, instead of quitting Track, I compete and improve my 1600 time to something like 5:01 or so. I'm on the verge of breaking five minutes in my next race -- and that's when the Track officials go on strike. (For COVID-93 during my freshman year, change it to 6:01 instead.)

Like my old LA county district, my current district always closes for Good Friday and Easter Monday. As usual, a Friday holiday shifts the block schedule. Odd periods are Monday and Wednesday, and even periods (and hence my blogging days) are Tuesday and Thursday next week before the four-day weekend.

Advisory in Review (Day 180)

Today is "A Day in the Life" for the special day "last day of school." It is the last day of final exams for juniors, with Periods 4-6 meeting today. But before we begin "A Day in the Life," I have much to say about today's schedule. First of all, recall that there are only two minimum days for finals this week instead of three -- one last effect of losing two January school days. (Something similar happened when I was a student teacher -- the school was short minutes and couldn't have three minimum days for finals. Instead, on the first day we have Period 1-2 finals for two hours each as usual, then it was Period 3-4 for 30 minutes each. The second day was similar, with Period 3-4 finals and short Periods 5-6. Only the last day was a true minimum day.) The juniors take their finals today, but not my Ethnostats juniors. Since seniors are a supermajority in my class, I already gave my juniors their tests on senior finals day. You may ask, what are t...

Chapter 6: What's Normal? Continued (Day 42)

Today is Columbus Day, or Indigenous Peoples' Day. While California schools don't close for the holiday, some districts hold a PD day today. My district, of course, had our PD day a week ago. Today in Stats, we cover the next three pages in Chapter 6, on Normal distributions. Here the students learn about finding the area between two z-scores. On the TI-83, this is the invNorm function. As for the TI-84, invNorm is just like the normalpdf and normalcdf functions -- mu and sigma are entered. This lesson goes more smoothly this time, since by now I'm expecting the TI-84 version of invNorm to be beefed-up from the TI-83 version. The exception, though, is in fourth period Ethnostats. For most of Chapter 6, the lessons for general Stats and Ethnostats are nearly identical. But since fourth period is larger than either second or fifth periods, everything goes more slowly. This includes the Warm-Up -- I must keep telling the students to be quiet while I read about the Hispanic Her...
