2-way Frequency Tables

COORDINATE ALGEBRA TEST # 1 IS TOMORROW!!!

Here are some places to find additional help with 2-way tables.

Textbooks (ever seen one in math?)

Yesterday in Accelerated Precalculus, we will pass out books for the students to use.

The state of Georgia has made some of their Georgia Virtual School on-line textbooks available.  This is a great resource with videos and examples.

This is what we did today:

Coordinate Algebra

3rd quiz of the semester, this time over Line of Best Fit.

We began a discussion on 2 way frequency tables.

Accelerated Precalculus

We worked on verifying trig identities.

Our homework was Pages 389-390, 11 - 17 & 41 - 51, all odd

Our 5th quiz will be on Thursday over simplifying trigonometric expressions.

Yesterday, I was out.  Coordinate Algebra worked on a quiz review and Accelerated Precalculus did some trig review problems from the book.

What happened today?

Coordinate Algebra
Mrs. Scaffe helped the class with a review for the quiz.  Tomorrow's quiz is over Lines of Best Fit.

Accelerated Precalculus

We worked with using the trig identities to simplify expressions.  Our homework, from our new books, is Page  382, 63-74.

Here's what Thursday looked like:

Coordinate Algebra:

We practiced Line of Best Fit some more.  We talked about whether correlation implies causation and the correlation coefficient.

Accelerated Precalculus:

We took our second test.  This test was over graphing transformations of trigonometric functions, solving inverse trig function problems, and word problems using right triangle trig.

Math Team Dates

Put these dates on your calendar:

Week of September 28: Math Madness Round 1 - likely during Titan Time, in the Math Lab

October 14 - Georgia Mathematics League Contest # 1 - likely during Titan Time, in Room 2209

November 8 - UGA Math Tournament - at UGA, usually in Miller Building, meet there at 8, awards ceremony at 1:30

9/3/2014

Here is what Mr. Lewis's classes looked like on Wednesday, 9/3/2014:

Coordinate Algebra Support:

We looked at doing lines of best fit by hand.  We discussed what the slope and the y-intercepts mean in context.  We also discussed correlation and whether correlation always implies causation (the answer is no!).  We watched videos of a class developing data to use in order to find a line of best fit.  We then practiced on the homework from Tuesday.
