We will be finishing our exam review today by looking at data management:

  • probability
  • types of data
  • ways of representing data
  • distributions
  • sampling techniques
  • measures of central tendency

With remaining time, you should be working on exam review and your course summative portfolio.

Reminder: Portfolios are due TOMORROW!

Thursday June 16, 2016

Today we will continue our exam review by looking at the material relating to personal finance:

  • Simple Interest
  • Compound Interest
  • TVM Solver

We will discuss these concepts, and you will try a few examples.

For the remaining time, you should be working on your course portfolio and/or the exam reviews.

June 14-15, 2016

Today, we will continue our course review by looking at trigonometry and geometry:

  • primary trigonometry (SOHCAHTOA)
  • The Sine Law
  • The Cosine Law
  • Function vs. Form
  • Isometric and Orthographic drawings
  • Nets and Patterns
  • Making a Floor Plan

We will discuss these concepts, and your will try a few examples.

For the remaining time, you should be working on your course portfolio and/or the exam reviews.

Course Portfolio Due June 23rd!

We will continue with our exam review today. We will look at exponential functions:

  • exponent, power, base
  • exponent rules
  • exponential relations

Each group will be assigned one exponent rule to summarize and add to a class table.

How can you simplify the following:

  1. (36 ÷32)÷34
  2. (-1335)0=
  3. (5)-3

Next we will look at exponential models. What is the general equation for exponential growth/decay? How can you tell if you have growth or decay?

In your group, try these problems:

  1. The population of Wikwemikong grows 15% per year. If the current population of the town is 1500 people, what will the population be in three years?
  2. Ms. Black’s Rav 4 decreases in value each year by 12%. If it is worth $8000 now, what will is be worth in 5 years?

With the remaining class time, you should be working on your portfolio and/or your exam reviews.

Friday June 10, 2016

Exam review begins:

Today we will look at quadratic relations:

  • comparing linear and quadratic
  • quadratic graphs: the parabola
  • vertex, factored, and standard from (using previous work)
  • expanding and factoring

Board questions:

Expand:

a) (3x+1)(x+2)

b) 3(x+2)(x-1)

What method did you use and why?

Factor:

a) x²+5x-6

What are the steps?

b) -4x²+24x+108

What are the steps?

There are several exam review questions to help you prepare for your exam. You should also use this time to work on your portfolio. Recall that the exam reviews might be a part of your portfolio.

Exam Review Problems

Wednesday June 8, 2016

Learning Goal
I am learning to
calculate mean, median, mode
determine when each measure of central tendency is appropriate


We will begin by discussing preparing for an open-book test. How will you prepare for your test tomorrow?

Next, we will look at a problem:

Two car salesmen are competing for a mid-year bonus. The owner of the dealership wants to assess the better competitor. Who is the better candidate?
Table - Car Sales

It all depends on how you crunch the numbers!

We are going to review different ways to interpret data sets using measures of central tendency: mean, median, mode by calculating and using technology.

How do you decide when each measure is appropriate?

Learning Goal
I am learning to
determine information about a population by looking at a sample
identify and describe different sampling techniques
critically analyze sampling techniques to determine if bias is present or if results are reliable


 

A sampling problem:

Nathalie Beauchamp surveys randomly from her on-line youth book club members as well as the lists of youth cardholders at the two nearest community libraries.
She returns to school and suggests to her friend on students’ council that the school should host a read-a-thon to raise money for prom since the participants in her survey all felt that it was a good idea.

What is the problem with her research?

What is the population she is actually studying?

We will examine some different sampling techniques today and discuss the pros and cons with each.

Then to sum up, we will play a game: NAME THAT SAMPLING TECHNIQUE

Finally, practice you knowledge of sampling techniques.

Exit Slip: Add new terms to vocabulary page.

Course work deadline is TODAY!

Learning Goal
I am learning to
determine information about a population by looking at a sample
identify and describe different sampling techniques
critically analyze sampling techniques to determine if bias is present or if results are reliable


 

First, you will be introduced to your first of two summatives for the course:

MBF3C Summative Math Portfolio

Next we will investigate animal populations… Have you ever read something like “there are 800 mountain gorillas remaining in the wild,” and wondered, “How do they know how many there are?!” How can biologists know this?

We will look at the mark and re-capture technique today: biologists catches some animals, tags them (without harming them), and then lets them go. Later, another sample is caught. The ratio of marked animals to all the animals in the second sample should be approximately the same as in the population.

#marked in 2nd sample = #marked in population
total # in 2nd sample             total population

Let’s define some of these terms:

  • population
  • sample
  • census
  • bias

You will simulate this experiment with moose. See PG 309 in your text. Work with a partner and get a population of moose. Don’t worry, they are only paper! You will follow the instructions to determine your population.

Complete the questions on PG 309 and the reflect questions and hand into the bin.
