Assignment for Friday, December 7, 2007

Due Monday, 12/10/07

The assignment is all from the packet you received in class. First, read the information, including making an effort to understand the examples. Then, try 1-11. (You may try #12 also, if you want a real challenge.) Finally, do the evens on the 4th page, which involve parallel and perpendicular lines and their slopes.

Next Monday’s assignment will include, but not be limited to, p. 593 #3, 4, 5, 7, 9, 12.

Assignment for Thursday, December 6, 2007

Due Friday, 12/7/07

p. 576 #1, 3, 5, 7, 11, 14, 15, 19

worksheet on point-slope form of equation #5, 7, 9, 19, 21, 23

Here is URL for the textbook’s website:

www.classzone.com/cz/books/geometry_2007_na/book_home.htm?state=NY

Just copy and paste the address into your browser.

When you get to the website, check out the vocabulary flipcards in the games and activities sections, and also the  Animations.  The flipcards are a great way to learn and/or review the vocabulary without having to make your own set of cards.  In the Animation section, there is an animation for lesson 4.8 that is a great way to learn and review the various transformations.  There are also some decent animations for chapter 9 as well, although some go into more detail than we will in our brief overview of this topic.

As with most websites, these features work best if you have something faster than a dial-up connection (like I do at home).

(Sorry for the delay in posting this.)

p. 276 #3, 4, 5, 9, 13, 15, 17, 20, 21, 27, 29, 33

p. 412 #9, 11, 13, 16, 17, 18, 19, 27

Also, work on your vocabulary worksheets, even though I may not check them.  Go to www.classzone.com for help learning the vocabulary by using the interactive vocabulary flashcards.

Hi everybody who is bored enough at home today to check my edublog!

I know you are all as disappointed as I am that we didn’t have school today, but we just have to take these things as they come.

I’ve kept busy today grading tests and fun stuff like that. I’m sure you’ve been just as productive as I have.

Okay, truth be told, I took a two-and-a-half hour nap this afternoon, and man, did it feel great! Slept right through both geometry classes!

Below is part of what I was going to assign for homework today, if I hadn’t slept through class. It is vocabulary, and I’m not planning on checking or collecting it. Honestly. However, it is in your best interests to know these words, and one of the best ways to learn vocabulary is to write out the words and what they mean. More than just reading the definition, the process of manually writing out the meanings forces your brain to process the ideas one or two steps further than if you just look at ink on a page. And then you remember them better.

Hope this help keep you from being so bummed about missing geometry class today.

Chapter 9—Properties of Transformations
Vocabulary Assignment #1

Some of the vocabulary comes from Lesson 4.8 starting on page 272 and from Lesson 6.7 starting on page 409.

Define or make a sketch of the following terms:

Transformation
Coordinate notation for a translation
Image
Translation
Reflection
Rotation
Congruence transformation
Dilation
Reduction
Enlargement

Our next chapter will be Chapter 9:  Properties of Transformations, but we are only going to hit the highlights.  We will explore basic definitions of translations, reflections, rotations, dilations, and symmetry, which will involve some coordinate graphing.  Speaking of graphing, we will also be starting our preparation for the Regents’ Math A Exam by reviewing coordinate geometry including graphing lines, distances, slopes, midpoints, and parallels and perpendiculars.  Then we will look at graphs of parabolas and circles.  It may seem, some days, that what we cover has nothing to do with what we went over yesterday, but in the end it will all come together.  We will be taking a test on the last day before the holiday break , but I will make fudge (chocolate, peanut butter, what do you want?–leave a comment) for you for that day to help ease your pain.
