Three-Week Update

Hi Math People Out There:

Well, three weeks of our 18-week courses are now in the books and I thought I'd give you an update on what's been happening in class – so, just scroll down to your class and get up to date.
40S Consumer (morning class):
Exploration 1 – Personal Finance (pages 22,23; # 1 – 8, (not 5(c)))
Exploration 2 – Mortgages (pages 32,33; # 1 – 8 all)
Simple Interest Formula Questions and Calculations
Exploration 4 – Gross Debt Service Ratio (page 53, # 1 – 3)
40S Consumer (evening class):
Exploration 1 – Personal Finance (pages 22,23; # 1 – 8, (not 5(c)))
Exploration 2 – Mortgages (pages 32,33; # 1 – 8 all)
Simple Interest Formula Questions and Calculations
Exploration 3 – Exploring Mortgage Payments – (just a discussion on this, no
questions were assigned – will touch on some possible questions later)
Assigned the first half of last year's Test 1 as homework.
Note: After class on Monday, Oct. 5, the morning class and the evening class will match again as they should.

20S Consumer (afternoon class): Here is an update of the last few classes.
- We've been calculating wages based on regular and overtime hours worked.
- Learning to tell time on the 24-hr. clock.
- Next we did payroll deductions and looked carefully at the examples on pages
56, 58, and 60.
- I introduced the % grid and we learned how to do questions that call for a 10%
or 12% raise.
The last assignment I gave was pages 73 – 75, # 1 – 11.

31G Math Essentials (evening class): Finished the “basics” and gave two quizzes. Gave the first quiz back to some and suggested that they finish the rest of the questions for more practice. If you are not getting 85 - 90% on the basics you need to keep practicing, because the first test is going to be all no calculator.
This Tuesday coming, Oct. 6, we will be starting into positive and negative numbers. I will also be doing some basics of algebra and geometry. If I stay true to my plan, I'll be combining the concepts where possible.
Your job is to get those basics of fractions, decimals and percents down as best you can.
See you in class,
Joe

Welcome To Math Class

Hello Math People!
OK, it's the first day of school for the 2009 Fall semester here at AEC's and I want to give you a heads up on what is going to happen over the next week. If you aren't feeling some kind of emotion (excitement, fear, anxiety, etc.) then . . . . We all get at least a bit nervous on the first day - teachers included. So here's hoping that your day is going / has gone well.
We need to think about what's going to happen over the next week, so here goes. The goldenrod coloured booklets that you were given have lots of important info but most important is the fact that there are some typical Consumer Math style questions in the back. After the first day pleasantries were over, we started into that set of mini lessons starting with Reading Charts Table 4: Tenants Package Policy. We will continue with the mini lessons on Wednesday up until our second tiny break.
At 8:17 or so, each student in the class will work on preparing an appropriate quiz in which they think best represents the lessons given up till that time. You'll then turn yours in and I'll choose the best one and that will be the Quiz on Monday, Sept. 21. If there is no best one, I'll simply pick and choose some good questions from several different students. The quiz should take the students 30 minutes at most to write on Monday. Of course, it may probably take longer than that to prepare.
So there you have it - our plan for the next week or so. See you soon.
Joe

The Promise

Hi everyone in Mathland:
OK, I promised that if you went to the blog you'd find the plan for Wednesday, June 3. Here it is in part.
Do the Chapter Review found on pages 345 - 348, # 1 - 8. Remember, this is all about types of variation, all four of which you should have thumbnail sketches in your formula booklets.
In addition to that, recall we started this unit off with plotting scatterplots and determining the slopes of lines. The slope stuff is contained in the direct and partial variation graphs, so I won't ask you any plain old "what is the slope of this line" style question. I'll just ask you to graph a few sets of data points and you try to come to a conclusion based on how the majority of the dots seem to appear. A good example was the physics versus math scores. Another example was the house number and an exam mark (I can't recall which exam :). There was no relationship at all in that one and you could not predict how well a person would do on a test just by knowing their house number.
So that's about it. The quiz should take about an hour or so, after which you can leave.
Have a great time studying!!
Talk to you soon.
Joe

Review class plan

It's Thursday, March 12, and I have lots to talk about but I'm sick and still sick. My plan was to have all the tests marked but it didn't happen - sorry about that. They should all be done Monday.
If you missed the Wednesday morning class do not despair. We'll do the lesson intended for Wednesday on Monday. I understand there were several regulars missing and those that did come didn't get a lesson, just an assignment, so Monday it is. See you then.

Getting Ready for the Test (and other things)

Well, it's been quite the week at school. The Income Tax has stretched us all hasn't it? But did you notice it wasn't about being smart or getting done quickly - it was about being willing to try something new and discovering something new. Just lecturing about income tax will put the most studious types to sleep so I thought the best way to approach it was by just jumping in and getting our feet wet and our hands dirty. Once we've experienced the forms we can go on. For now let's put it aside and deal with the test.

As promised, here is a question that will be on the test and its answer. #4 on page 3 which says, "If the Jones buy the house, they want to move in on Sept. 1. The current owner has already paid the taxes for the year and they amounted to $2,142. What would the Jones have to pay (dollar amount) and what is that item called?" Answer: $2,142 x 4/12 = $714. It called the property tax adjustment and it is one of the closing costs.

So I'll see you on Monday - have a good weekend.

Joe

Four weeks in

Welcome to a new semester!

So, a new batch of faces has graced our humble school in the North End of Winnipeg. Just like last semester, it's turning into a fun learning experience for everyone (if not, let me know). Here's an update on the last piece of work that we did. We finished the Chapter 1 Review. Now, if you were not here just do the following: 1) Turn to page 66. 2) Look at each question and take a moment to recall the topic to see if you remember taking it. 3) Make note of the ones you can't do and be prepared to ask either Me, Brianna, or Kirby. 4) Do the ones you can do.

That is most certainly not all we did last night, but it will give you an idea of where we're at.
On Monday I'll be giving out the answer key (there is none included in your duotang on purpose).

On Monday we will beginning a super short Income Tax unit. The plan is to be done by coffee time on Wednesday. We'll also be discussing some test-taking strategies for the test that's coming up on Monday, March 9.

Hi All:
OK here is the promised info for the exam on Monday. Remember, it was about the pennies in the foam cup demonstration. We don't have graphics yet so I'll give you the questions and the answers to go with them.
Write these answers down in your Blue Formula Sheet notes and bring them with you to the exam.
a) Why do the points not lay perfectly on the line? (because the values of stretch were rounded to the nearest 0.5 cm)
b)What is the dependent variable and what does it represent? (the dependent variable is 'S' and it represents the amount of stretch)
c) What is the meaning of the point (40, 31)? (it means that when 40 pennies are in the cup the elastic stretched 31 cm.)
d) Draw a line of best fit and determine the slope of the line. (Draw a line exactly between the points
(0, 26) and (100, 39). The slope of the line is 13/100 which is exactly 0.13.)
e) What type of variation is it? (It is a partial variation.)
f) Give a formula for this relationship. (S = 0.13n + 26)
