preCalculus 2016-2017: Trigonometry (September)

preCalculus 2016-2017:
We are currently reviewing all of Trigonometry! September was all about CH06: Unit Circle and Trig Graphs plus UNIT07: Trig Identities and Equations. We start with Trigonometry because some students didn't take Algebra 2 and Trig last year. CC Algebra II does not have a lot of Trig.

This year I'm trying something new:
MCQ Mondays,
TakeHome Tuesdays,
YouTube Wednesdays,
FRQ Fridays.

MCQ Mondays will start in October. Even months we will do practice MCQ Exams using Formative Assessments via Socrative. On odd months we will have actual Mock MCQ Exams as Summative Assessments.

TakeHome Tuesday is when I collect TakeHome Exams. Most tests will be TakeHomes given on Friday and collected on Tuesday.

YouTube Wednesday is infamous for STEAM related Filks as well as month long Documentaries from National Geographic or Nova on PBS.

ThinkPairShare Thursday is when the students get into groups of 2 or 3 with a WhiteBoard to review HomeWork questions they had trouble with.

FRQ Fridays occur at the end of every 2-3 week unit. On Friday I give a preTEST review sheet. We go over it using ThinkPairShare again. The real TEST, similar to the preTEST, is then given at the end of the period as a TakeHome Exam due the following Tuesday.

Chapter 6 ScreenCasts
We talked about "SOHCAHTOA East of Java!" In other words, we developed the idea of finding exact values for the sin(x), cos(x), tan(x), sec(x), csc(x) and cot(x) of certain reference angles, in degrees and radians, in all 4 quadrants! We also graphed y=sin(x), y=cos(x), y=tan(x) and their transformations! Last, but not least, we worked with non-Linear Regressions!

Chapter 7 ScreenCasts
Now we talk about Proving Identities vs. Solving Equations. We graphed y=sec(x), y=csc(x), y=cot(x) and their transformations. We learned about the inverse trig functions arcsin(x), arccos(x) and arctan(x) and how to use inverse functions to solve equations.
