posted list of topics on the spring final in Files below. If you CTRL-click on the links you can choose Extra Examples and it will bring up more basic practice for each type.

**04.06.10**

Uploaded 2 documents with practice problems of the 500 problems.

**NOTE:** I have received one(1) plan of study in writing. That means everyone else has a zero(0) for this first assignment. If you gave it to Mr. DePauw, you want to get it back and turn it in the appropriate bin as soon as possible to minimize loss of points on Work Ethic grade.

Geometry Independent Study

Alright, normally at this time in Geometry class we would hit all the formulas and work our way through these over the next three weeks until TAKS so they are fresh in your mind. Now that were working within the new schedule, we have an incredible opportunity for you to attack this activity in a way that you choose.

Traditionally, this topic is taught as some examples on the board and then time for you to work out the specific details and errors through homework. There are about 20 formulas that you'll need to juggle, and based on the standard of 20 questions to really grasp each concept, I recommend about 500 practice problems.

That's my first offer: I'll put the formulas in the files below and start adding the 500 practice problems for you to work through. And you set up a schedule for the next three weeks (12 hours of class time) to complete them, with some quizzes thrown in to test your preparation.

OR…

My second offer: you can come up with a different plan on how you will a) memorize the formulas, b) apply the formulas to find area, surface area, or volume from the given information or diagram and c) apply formulas to find missing values from the given area, surface area and volume. Your plan will also need to include quizzes to test your preparation.

TEST 11.11 and 11.12

You can use

classzone for some practice problems. Go to the Chapter Tests or the workbook and do section practice. Do remember that this book uses theorem notes that we don't: "corr angles theorem" instead of "|| forces corr angles congruent".

Several students expressed that having the weekend to finish up the u1d4-plp.doc would help them study and relieve some stress. I'll allow it. All packets are due, in the tray or digital, by 8:30a.m. Monday, 09.28.09. Be careful, if you email it that morning, know that my email server takes time to receive and I will assess the late-tax.

I also shared my started "Axioms List" in the files section below. Let it be the start of your own.
