12-4-2006 Test today. Last Math Test unless you need to take the Final. See you with grades on Wednesday.
11-27-2006 Covered 5.3 examples #6, 7, 8 and assigned homework Ch 5.3 #s 2, 10, 14, 30, 42, 54. due on Wednesday. Friday we will have a Quiz on Ch 5.3 and I will hand out Test #3 Part 1 Take Home and on Monday next we will have Test #3 Part 2. Part 1 you may have advice from others, but must do the problems yourself. Part 2 In Class you will be on your own. The test is comprehensive and will be modeled on Part 1. Then God willing and the river don't rise -- on Wednesday we'll have DOUGHNUT DAY! and give out grades and stuff. Maybe new puppets will attend since the ones that were there today had such a good time. The frog was particularly flattered that I said that he knew everything. I was exaggerating of course!
11-17-2006 Completed 5.2 and assigned homework listed below. There will be a Quiz (teams allowed) on Monday on 5.1 and 5.2 and we'll also be going over 5.3 which shows how to use the properties of logarithms to solve exponential equations.
11-15-2006 Went over some of the problems in Chapter 5.1 and Demonstrated curve fitting using Excel Spreadsheets. Began discussing Logarithms. No Quiz on Friday -- plan for a Quiz on Monday on at least Chapter 5.1 and some of 5.2. Homework for Ch5.2 is #s 2, 8, 14, 20, (hint look at #17), 24, 26, 28, 38, 58.
11-13-2006 Covered Chapter 5.1 and assigned homework problems 5.1#'s 4, 16, 20,26, 30, 36, 42, 44
11-10-2006 Gave test on Chapter 2
11-8-2006 Reviewed homework problems and handed out the Part 1 of the two part test and started, just barely, Chapter 5.1 Exponential Equations.
11-6-2006 Gave an overview of what we've covered so far: 1) Polynomials, 2) Linear Functions y=mx+b, 3) General Quadratic Equationwhich when f(x) is zero always has two solution set by the general solution to the quadratic equation. Also discussed the business applications: Profit = Revenue - Cost. The Break Even Point is where costs and revenue are equal. The we looked at Supply and Demand. The Supply Equation: more is offered when prices are high than when they are low. The Demand Equation: more is bought when prices are low than when prices are high. And Market Equilibrium when supply and demand are in balance. The effect of a Tax is to increase the supply cost and therefore reduce the demand. (Produces a new market equilibrium point.)
11-1-2006 Today we will be covering Chapter 2.3 and we'll continue with 2.4. There will be no quiz on Friday so we can cover the rest of Chapter 2. Next Friday we will have a TEST on Chapter 2. Homework is assigned today to collect on Monday. The Homework is the following problems: Ch 2.2 #s 4, 10, 14, 18, 32, 44; Ch 2.3 #s 4, 12, 26, 32; Ch 2.4 #s 16, 22, 30, 34, 46, 50. That's a total of 16 problems. Next Monday will be Question Day and we will start Chapter 5 on Wednesday and have a test on Chapter 2 on Friday.
10-30-2006 Handed back 1.6 homework and covered Chapter 2.2 in particular the characteristics of maxima and minima in a quadratic equation. The axis of symmetry is found at -b/2a and the nature of the discriminant: b-squared minus 4 ac. No homework was assigned. Plan to go over Chapter 2.3 and 2.4 the rest of the week and have a test next Friday on Chapter 2. Then we will proceed to Chapter 5.
10-23-2006 Handed back quizzes -- Completed through Section 1.6 at the conceptual level but need to do some examples. Next time we'll do some examples of 1.6 and start 2.1 so we'll put off the homework for 2.1Chapter 2.1 #'s 2, 8, 20, 26, 34, 40, 46, 58 until next Monday. THERE WILL BE NO CLASS ON FRIDAY. I will be handing out a quiz on 2.1 on Wednesday which will be a take home quiz.
10-20-2006 QUIZ Chapter 1 section 1 through 5.
10-18-2006 In view of the fact that we didn't really have
enough time in class today to go through 1.6 except in the highest level terms,
let's put off the 1.6 homework until next Wednesday. We'll cover the concepts and
application in more detail on Monday and we'll do 2.1. So Wednesday's homework
for next week will be the 1.6 homework assigned today and the beginning of
Chapter 2, section 2.1 and the homework for Wednesday will be problems from both
Section 1.6 and 2.1:
Chapter 2.1 #'s 2, 8, 20, 26, 34, 40, 46, 58 and Chapter 1.6 #'s 2,
8, 14, 16, 26, 36, 46, 56 now both due next Wednesday, October 25th.
There will be no class next Friday, October 27th but I will hand out a take home Quiz which you can work on. That Quiz will be on sections 1.6 and 2.1.
10-17-2006 On Wednesday we'll be doing then end of Section 1.5 and Section 1.6 -- Homework will be Chapter 1.6 #'s 2, 8, 14, 16, 26, 36, 46, 56. The Quiz on Friday will be a group Quiz on Chapter 1. through 1.5.
10-16-2006 Passed back the 1.3 homework. We skipped 1.4 since it is only about calculators. If you have a TI-83 or 85 or other graphing calculator you might find the section interesting, but it is more about what are called "numerical methods" than algebra. We started looked (for the second day) at solving systems of linear equations. The easiest are two equations in two unknowns (x and y). These can be solved either by Substitution or by Elimination. Assigned homework for Wednesday for chapter 1.5 #'s 4, 8, 12, 18, 26, 30, 36, 50. It's important to note that I only assign homework because otherwise I've found that you don't do the work. It is rather irresponsible of almost grown college students to be so unreliable that they can't be counted upon to do the work -- but there it is. So to try to help you I assign homework to pick up and grade. What you should be doing is all the problems at the end of each section, checking yourself by looking at the answers to the odd numbered problems in the back of the book. Then you would know which areas you were having difficulty with. You could and should then go back over that section of the book to improve your understanding. If you still don't understand it you should prepared questions to come to class with. That's what it means to be a responsible student. An irresponsible student is someone who is wasting his money or his parent's money by coming to college without intending to put in the effort to learn. If it is his own resources he or she is wasting why very well -- it might not be smart but it's your call. If it is someone else's resources that you are wasting then it is no different than theft. It's just theft in another form. I'd like to encourage you to be responsible students and work hard and get the material. I'll do whatever I can to make that happen.
10-13-2006 Friday the 13th -- we went over some homework problems and then we basically skipped over section 1.4 and started on 1.5 which is about solving systems of linear equations. The grading methodology is an example of how I handle the grades. I call it Cluster Grading and it's designed to let a student have some bad results and still not get hammered. On the whole it won't help if you are consistently good or consistently bad. It only helps if you're one of those folks that generally do well and mess up once in a while.
10-11-2006 Hope everyone had a great Fall Break. Homework, if you forgot, is Chapter 1.3 #'s 4, 6, 14, 18, 24, 40, 52, 58. It is due on Friday. The Grading for the Mid-Term Grade will be: Homework (worst thrown out) 10% of your grade, Two Clusters Cluster Graded 60% 40% for the other 90% of the grade. The Clusters are: 1) Best of Two Tests, and 2) Average of Best Two of Three Quizzes.
10-6-2006 The Make-up Test -- went off fairly well except that the chocolate only barely held out. Tee wants Reese's Pieces next time and put in his order. Tony Franklin thinks he should get a Correction Point for finding that problem #11 was confusing -- typo-City. I don't know what happened there. My excuse is that it looked good on the screen when I typed it. Wha-happened? Anyway and points to be awarded are being investigated by the grading committee.
10-4-2006 Went over the last few problems on the Test and a few of the problems on the Homework (1.1 and 1.2 homework). Tomorrow from 5 to 7:30 p.m. I will come to McK-223 and we can do problems and get explanations. Please bring your books and the specific questions which you are having trouble with.
10-2-2006 CRASH and BURN -- the average test result was 44% -- Time to hit the books folks! We can't have that. So we went over most of the problems from the Test in class today -- we'll finish the couple that we didn't get to and then we'll have a similar repeat test on Friday.
9-29-2006 TEST Chapter 0.1 to 0.7
9-27-2006 Today is QUESTION DAY -- we'll also finish 1.1 and look at 1.2. Don't forget the Test on Friday -- it's not a group test, so study the material in Chapter 0.
9-25-2006 Today's material is Chapter 1.1 and 1.2, but we didn't finish it. We covered the two harder problems on the quiz and then covered most of Chapter 1.1. We'll finish those on Wednesday. The HOMEWORK on 1.1 and 1.2 is due next Monday. HW Chapter 1.1 #2,4,8, 16, 20, 26, 30, 42, and Chapter 1.2 #2, 6, 8, 18, 26, 28, 40, 50 (a total of 16 problems). Homework is really the minimum you should be doing. You really should be doing ALL the problems at the end of the chapters. That way you will 1) Really learn the material and 2) since I often take some or all of the quiz and exam problems from the even numbered problems, you will also find that you've done a good percentage of the problems on the exams.
9-22-2006 Quiz on 0.6 and 0.7 given today. Group quiz. The quiz average was 6.62 out of 8 or about 83% -- which isn't all that great given that everyone got the extra credit -- without that the average would have been about 71%. Don't forget there will be a test next Friday on Chapters 0.1 to 0.7.
9-20-2006 Today we'll answer questions on 0.6 and go through 0.7. On Friday we will be having a QUIZ on 0.6 and 0.7 instead of the originally scheduled TEST -- we'll do the TEST next week.
9-19-2006 Slaving away marking homework. NEATNESS COUNTS! I think we'll only have a quiz on Sections 0.6 and 0.7 on Friday because based on the homework, I don't think we are quite ready for a TEST. Whew! Only three more ...
9-18-2006 Went over basic factoring 0.6 and got to Example 6 on page 39. We'll take up from there on Wednesday. The homework for section 0.7 is HOMEWORK 0.7 (48-49) #s 2, 8, 12, 22, 40, 48, 52, 58. This HOMEWORK will be due on Friday. There will be a TEST on Friday on Sections 0.1 through 0.6. Handed Section 0.5 Quiz back -- most people did well.
9-15-2006 QUIZ on Chapter 0.5 Today and some work on 0.6 -- well we didn't get to cover 0.6 today -- since it is mostly straightforward I'm inclined to say that the homework should still be turned in on Monday -- but we'll turn it in at the end of class so you'll have some time to correct your mistakes if you made any. I'll take our present state of progress into consideration when deciding how much we'll cover next week and let you know on Monday what the strategy is. Have a very nice weekend!
9-12-2006 HW#3 is Chapter 0.5 (pages 34-36) #s 4, 6, 10, 14, 18, 32, 46, 62, 72 and Chapter 0.6 (pages 41-42) 4, 6, 10, 14, 20, 24, 54, 62. It is due on Monday September 18th. Question day will complete Chapter 0.5 and we'll do at least some of 0.6. Quiz on Friday will be on 0.5.
9-11-2006 We got through 0.5 (29) Ex. 4 Symbols of Grouping. No homework problems were assigned. The homework for the next two sections 0.5 and 0.6 is: Homework 0.5 (pages 34-36) #s 4, 6, 10, 14, 18, 32, 46, 62, 72 and Homework 0.6 (pages 41-42) 4, 6, 10, 14, 20, 24, 54, 62. Next time we start off where we left off and have questions when we finish 0.6 (if we do). The Quiz will probably be on Section 0.5 on Friday.
9-11-2006 I graded the quizzes over the weekend -- the results were fairly disappointing. No-one "got it" that pi > 3.14 -- that might have been because there was an em-dash before the pi, but no-one even asked. The conundrum is whether to stop at this rather elementary point or plunge on and do sections 0.5 and 0.6. We'll see how it goes.
9-8-2006 We had a math quiz on chapters 0.1, 0.2, 0.3 and 0.4 today -- it was a team quiz with runners and teacher hints. The reason is
The homework grades were pretty disappointing -- working out to an average of about 50% in the first homework and 56% in the second (Hey at least there was improvement right?) So I thought a team quiz would be more helpful than just having you all crash and burn on your own. We'll see how that grades up. Unfortunately most of your only learned how to use your calculators in high school and that just isn't good enough for college. We'll fix it though!
One of mine is The Day the Earth Stood Still an old science fiction movie from the early 1950's. It was only the first or second movie that I ever went to see. I also like Chariots of Fire, and 2001 A Space Oddessy, and a lot of others.
Homework Assigned 9-1-2006 Friday Due Monday 9-4-2006: Chapter 0.1 pages 6 to 8 #4,6,8,14,16,24,30,32,52,58 and Chapter 0.2 pages 13 to 15 #2,4,10,18,26,42,48.
MOVIES: Grandma's Boy got a 3, 40 Year Old Virgin and Wedding Crashers got 2's, and all the rest had only one fan: Super Troopers, Finding Nemo, Yellow Submarine, Deerhunter with Denise(hmmm), Madeia's Family Reunion, Office Space, Pretty Woman, Basketball, Man on Fire, Happy Gilmore, Underworld, Talldogs Nights, Boondock Saints, Dirty Dancing, Friday, Braveheart, Goonies, Any Given Sunday -- listed in no particular order.
Homework Assigned 9-4-2006 Monday Due Wednesday 9-6-2006: Chapter 0.3 pages 18-20 # 4,6,14,24,38,50,62,64 and Chapter 0.4 pages 25 to 27 #2(a,b),4(a,b),10,12,18,28,36,44,58,68,70,74.
Then Wednesday is QUESTION DAY! -- you have to stay for the whole period and if we run out of questions we'll do more of the book.
We will be having a QUIZ on Friday Sep 8th on problems drawn from Chapter 0 section 1 through 4. (0.1 to 0.4) We'll have a little more Question time before the QUIZ on Friday -- so study and if you have problems, try to come with precise questions that can be answered in the first twenty minutes or so on Friday. Sometimes COOL THINGS happen!
I was thinking that maybe MONDAY should be called FIRE HOSE day when we blitz through two sections of the book. The idea is to try to clearly present the ideas in the book on that day. So if you don't get it -- stop me and we'll try to explain any difficult points. The QUIZ and HOMEWORK results will also be used as RUDDER COMMANDS, i.e. signals to steer a little into more explanation on the sticking points and such.
