Geometry Monthly Schedule

(Periods A and B)

M 12/1/03	HW due (70 minutes): Using compass and straightedge, construct the nine-point circle for a large triangle. You may use your cheat sheet. Then write (on pp. 264-267) the following review problems: #1, 2, 3, 5, 7, 11, 15, 19, 25; also do #63-68 from the practice midterm exam. In class: Review for test. After school: Check out this blank copy of the Polygon Feature Chart. Fill it in as quickly as you can, and then check your answers against the answer key. You will also enjoy looking at these detailed solutions to selected review problems. I also dredged up an ancient test and modified it to make a practice test on Chapter 5 and PBT. I probably shouldn’t have done this, but I even created a solution key for the practice test.
T 12/2/03	Test on Chapter 5, nine-point circle, PBT. You may use a cheat sheet containing nine-point circle instructions, as detailed as you wish, plus the acronyms ABIC, MCCG, ALTO, PBCC. You may even include construction instructions (perpendicular bisector, angle bisector, or dropping a perpendicular from a given point to a given line). However, you may not include polygon features on your cheat sheet, nor should you memorize the feature chart. Rather, you should practice thinking (yes, actually thinking) to come up with the answers. Not all questions can be answered from the feature chart. Sample question: What type of quadrilateral has two pairs of opposite sides congruent? Answer: A parallelogram. To say “square,” “rectangle,” or “rhombus” would be assuming too much, even though the property is clearly satisfied by squares, rectangles, and rhombuses. Sample question: What would you call a quadrilateral that has congruent diagonals? Answer: Nothing special. The name “quadrilateral” is the most descriptive name that applies. Sample question: What would you call a quadrilateral that has two pairs of congruent sides? Answer: This could be a kite (“aabb” pattern) or a parallelogram (“abab” pattern). If forced to choose a single name, we would have to say “quadrilateral.” Sample question: Are there any kites that are also parallelograms? Answer: Yes. We usually call them rhombuses.
W 12/3/03	HW due: Do the practice test on Chapter 5 and PBT. Take the test without using any notes, and then use the solution key to correct and score your test. Use a different color of writing for your grading marks and corrections.
Th 12/4/03	HW due: Read §6.2; write §6.1 #1-6 all, §6.2 #2, 3, 7.
F 12/5/03	HW due: Read §6.3; write §6.3 #1-7 all. We will have class as usual today. (The House Tour does not affect Room S.) Congratulations to Marcus and Harrison, who corrected a fairly serious speak-o from the class discussion on Thursday, 12/4. The rotational speed of the earth at the equator is about 25,000 miles per day, not 25,000 miles per hour. Yikes! What was I thinking? The speed is still very great, but it is only about 1,000 miles per hour. Good catch, gentlemen! (A bonus point has been awarded.)
M 12/8/03	HW due: Cumulative review, pp. 291-293, all problems. If you run out of time, you may focus more on the problems that are challenging. However, it is best to work all the problems so that you can start getting your mind in gear for the midterm exam in January. It’s about time to start studying for the midterm, by the way! Please devote a few minutes each night toward reviewing old material and working on the practice midterm exam. Please remember, it is not good enough to be able to “scrape through” the problems. You need to practice doing them repeatedly to build speed and proficiency.
T 12/9/03	HW due: Read §7.1 (remember, reading notes are required as always); write §7.1 #1, 2, 9.
W 12/10/03	HW due: Read §7.2; write §7.1 #19, §7.2 #2, 4, 5, 6, 8.
Th 12/11/03	HW due: No reading assignment. You may read §7.3 if you wish. Your assignment is to make the correction described below and to write §7.3 #1, 2, 5, 8, 10, 13, 14. Important: Your textbook contains a serious typographical error near the bottom of p. 308. The word “convex” should be inserted before the word “polygon” in the statement of Theorem 57. Make this change, preferably in ink.
F 12/12/03	Both classes will meet today in Steuart 202. This is not an “every Friday” thing, just something that Mr. Graham requested for today so that his classes could use the computers in Room S. HW due: §7.4 #1-6 all, 9, 13. Also, start working a little bit each day on your practice midterm exam. Remember, perfect Þ practice.
M 12/15/03	HW due: Review problems, pp. 320-322 #2, 5, 7, 9, 10, 13, 15, 19, 21, 22. Many of you also need to patch up your proof of §7.4 #9, using the hints that were given at the end of class on Friday.
T 12/16/03	HW due: Read §8.1; write §8.1 #1-4 all, plus any problems from yesterday that you could not finish. Be especially sure that you have a clean version of §7.4 #9 ready to be graded.
W 12/17/03	Test on Chapters 6 and 7. Study your review problems from Chapter 7 a second time. Here are some suggested review problems from Chapter 6: pp. 288-290 #1, 2, 4, 5, 9, 10, 16.
Th 12/18/03	HW due: Read §8.2; write §8.1 #6, 10, 11, 14, 15, 21, 22, §8.2 #2-7 all.
F 12/19/03	HW due: Read §8.3; write §8.2 #9, 14, §8.3 #1, 2, 8. This assignment is shorter than usual so that you can attend the Lessons & Carols service on Thursday evening.
