Chapter 9 Lesson 2 PROBABILITY

Good day girls and boys.  

We are continuing on with PROBABILITY. And the first video is on vocabulary so make sure you write these down in your Graphic Organizers and define them as well.  These 2 terms work together - Theoretical and Experimental PROBABILITY.  Starting with Experimental Probability is when you actually DO the experiment and Theoretical is when you have an equal chance at the outcomes, but you don't actually do them.  So, these should be relatively close but if the Experimental time is not done many many time, it often does not come close to the Theory one, what mathematically should happen.  Watch the videos and take notes.

Chapter 9 PROBABILITY!!!

Good day to all of you,

We are moving on with PROBABILITY!  And Probability is a unique strand in math - it has many symbols. So hang on for the ride !  Starting with Vocabulary: Probability is the chance that something may happen.  You hear this all the time when you hear the weather forecast- we have a 70% chance of rain tomorrow.  The weatherperson can not say for certain that it will rain, 

but it is likely. Simple Event is the outcome( is the answer/result of something happening.  Random is when all outcomes are equally likely to happen. And the last vocabulary for this lesson is Complementary Events- that is - 2 events can happen BUT not at the same time- as in- I toss a coin and it lands on heads- it could have landed on tails - but can't land on both heads and tails at the same time.  These complementary events

 ALWAYS add up to 100 % or 1 !!!

Chapter 6.8 Solving 2 Step INEQUALITIES

Good Day to all of you,

Today we are moving onward with solving 2 STEP INEQUALITIES- This is your vocabulary term.  This means that you are going to be solving 2 steps to get the solutions.  As in EQUATIONS, you start on the Variable Side - Balance the Constant ( number that stands alone) on both sides - then take care of Balancing the Coefficients (number that is part of the variable).  REMEMBER the trick: When multiplying or dividing across the INEQUALITY, you must flip the < or > signs. In your graphic organizers write the vocabulary terms and definitions for 

 2 STEP INEQUALITIES - CONSTANTS - COEFFICIENTS  - PROPERTIES of INEQUALITIES!!! 

And....... you are in for a special treat today with a couple of your peers who solve the problems for you!!!! If you want to do this, please let me know......

Chapter 6.7 INEQUALITIES Multiplying and Dividing

Good Day Girls and Boys!

We are moving onward with inequalities, but this time solving these using multiplication and division.  These are still one step inequalities, but in the near future we will be solving for 2 step inequalities.

Your vocabulary terms for this lesson are...you guessed it...Multiplication and Division  Properties of Inequalities!  So make sure to define these in your portfolios! 

Remember that I spoke about the little twist in solving Inequalities from Equalities????? Well, check out the KEY CONCEPT on page 507 in your textbook and there it is!  When solving for multiplication or division with NEGATIVE NUMBERS you flip the SIGN!!! We will go over this in class so don't panic! 

WRITE THE CONCEPT IN YOUR GRAPHIC ORGANIZER!!

Chapter 6.6 INEQUALITIES in EE Standard

Good Evening Girls and Boys,

I hope your vacation was everything you planned it to be.  Now that you are rested up and ready to start MATH, we will begin with INEQUALITIES.  This is the first vocabulary term and it means that the solution to the problem has MORE THAN ONE ANSWER or solution. For instance: I have $100 in my pocket for groceries for the week. I can spend anywhere from $100 to $0 for groceries, not a finite answer.  

The other vocabulary terms are Addition and Subtraction of Inequalities- and these are the rules, laws or principals that allow you to solve these inequalities. Check out page 498 for some interesting reading in the KEY CONCEPT box.  

You will find that solving inequalities is much like solving for equalities.  They use much the same properties but hang on- there is one tricky part to this that is coming your way soon.  So stay tune and wait-

Chapter 8.5 VOLUME of a Pyramid in the Geometry Standard

Good Evening Girls and Boys,

Today we are building on with the last lesson on 

VOLUME of Prisms and exploring

 VOLUME of PYRAMIDS! 

 Volume is the same: 3-D or 3 dimensions - L W H but now we are working on pyramids.  And if you recall, in the 6th grade you studies these structures a great deal. 

 We will find out the capacity or how much it holds by using our Volume formula ( Shortcut) for Pyramids :

 V=1/3 LWH ! 

This formula looks fairly bazar, but we will look at this closely in class.  Make sure you write down the formula for 

volume in your graphic organizers!

Chapter 8.4 VOLUME of PRISMS in the geometry strand

Good Afternoon Ladies and Gentlemen,

The changing of the guard has happened- I am back!  The last 3 chapters have been a bit more choppy and we will be finishing these, starting with the end of chapter 8 on Geometry.  We will review in class the vocabulary as this is upmost important in math but especially in Geometry.  But in this section we are looking at formulas ( shortcuts ) again and 3-D shapes, in particular, PRISMS.  This is your first vocabulary term for this section.   A prism is labeled by the bases, if the base is a rectangle, the prism is a rectangular prism.  And if the base is a triangle, it is called a triangular prism.   Prisms are everywhere: Cereal boxes, tents, wedges, and so on...... bet you can name many. Prisms is your second vocabulary term.   And in this section we will find out the Volume of the prisms.  That is how much the prism can hold if it were to be filled up. The formula for volume is V=BH (or V=LHW)  for a rectangle prism or V= 1/2 BH ( 1/2 LWH) for a triangular prism. These formulas are similar to the formulas for rectangles and triangles.  This sounds confusing, but hang on , watch the videos, take notes, and ask away with questions.  Make sure you write in your vocabulary terms in your graphic organizer.

Who is this little elf?????
