CHAPTER 3 Integers and Absolute Value Strand: NUMBER SYSTEMS

Dear Girls and Boys,

Today we embark on a new frontier!  Rules will change so stay tuned to learning new rules.  One change is that we will be doing far less online worksheets and working mostly in your textbook! This will mean that you will be taking home your textbooks when you are not done with the classwork.  You will be able to complete the work in your textbooks and use your working spirals when you need to.  We will be doing computation problems as well as word problems so that you start to LOVE the word problems! The longer it takes you to love them, the longer we work on them!  

This chapter is about INTEGERS and ABSOLUTE VALUE.  

Many of you already have a nice grasp on integers so this will be a review.  Integers is using both the positive( above 0)  and negative ( below 0) whole numbers.  You find these in the real world when you are talking about temperatures, such as - 6*- or below sea level - or on a football field going back 20 yards - working on a graph and plotting the ordered pair, ( -2, 3) and many other applications.  Absolute Value is the DISTANCE between a number and 0. Distance is always positive as you can never travel in the negative. It is written much like a goal posts with a number inside- I -6 I = the distance between -6 and 0 so that is 6.

Lesson 8 - Simple Interest

Good Day to all of you,

This is the last lesson of the chapter on percent!  This also means that you will be taking a test in the very near future.  But before the test happens, we need to cover SIMPLE INTEREST.  Simple Interest is the money earned or paid for the use of your money.  It can be found by using the formula, shortcut, I = PRT. That is Interest = Principal * Rate * Time.  We will go over this formula after we learn about the parts of it. I = interest  P = principal   R = percent charged or earned  T = time.

The PRINCIPAL is not Mr Riley in this case! The Principal is the money you deposit or borrow.  The 2 vocabulary terms for this lesson are Simple Interest and Principal.  Make sure you glance back in this paragraph for the meanings and include the formula for simple interest.  

So, hang on....... and ask questions if you have them especially after going through the examples on the videos. 

Take at least 2 notes from the blog onto the graphic organizer.

Lesson 7 DISCOUNT

Hi Girls and Boys,

Now we are finally at my FAVORITE lesson- Discount!!!!  Yippee..... I love a bargain.  This lesson is similar to Lesson 6 on Sales Tax, but in this lesson we are SUBTRACTING the Discount or Markdown percentage!  Yippee.....I love a bargain.  

The tricky part is that in this lesson and real life you will be subtracting the discount but adding in the sales tax.  So be careful and learn about everyday buying in the real world.  

The 2 vocabulary terms for this lesson are Discount and Markdown.  Both of these are the amount of the price that reduces the selling price.  

This is the last lesson in this chapter so you know what that means!!!!!

Please jot down 2 facts from the blog into your graphic organizer.

This is Hayden's puppy he is getting in the near future!  It's a lab doodle!  Don't you just want to cuddle with her?!

Homework: Read the blog and take notes.  Watch the videos and take notes in your graphic organizer and complete your vocabulary for lesson 7- DISCOUNT.

Lesson 2.6 Sales Tax, Tips, and Markup

Good evening Girls and Boys,

We are now diving into a lesson on paying extra money! No fun at all!  We are going to learn about Sales Tax, Tips or Gratuity, Markups and Selling Price.  These 5 are all of your new vocabulary  terms for this lesson.  You and your family see these every time that something is purchased so you may be very familiar with these terms.  Sales Tax is what the state and national government tack onto to prices to run the governments.  Tips or Gratuity - both the same- are the amount you would give a person for service given- such as a waitress.  A store will Markup a price to customers from what they paid for it and what they sell it for. And the last term is Selling Price that goes with Markup.  The price that store owners sell items for after the markups is called the Selling Price. And please excuse me for sneezing on video 2 at the end.........

Here is Ava at her family reunion.  She is making homemade sausage, a family tradition.  YUM!!!

Homework:

Read the blog, take 3 notes from the blog and record in the graphic organizer, Watch the videos, take notes in your graphic organizer and complete all 5 vocabulary terms in Lesson 2.6- Sales Tax, Tips and Markup.

Lesson 5 PERCENT of CHANGE

Good Day to all of you,

This lesson is about change, Percent of Change.  What do you think of when you use the word CHANGE? Is it, you start with something and then that changes into something else??  Well, in Percent of Change, you are talking about the original amount and the amount that it changed to as a ratio.  This change can be a decrease or increase.  There are shortcuts, formulas, that you can use to solve these percent problems.  You can use these formulas to find out how the price of gas has changed over a period of years, how much the price changed for any sales item, or many other items that can change.  If the change goes down, you would find the Percent of Decrease. And if the change goes up, you would find the Percent of Increase.  And if you are estimating, the change in the actual and estimated amount is the Percent of Error.  

So, there are 3 formulas to help out with the solutions to each type of problem.  Make sure that you look over the key concepts on pages 144 and 145. 

You must write down 3 facts from this blog into your graphic organizer.  

 These are Catherine's little sister and nephew.  They sure are sweeties!

Homework: Read the blog, watch the videos and take notes in your graphic organizer, and complete your vocabulary terms.
