Chapter 5.5 Simplifying Expressions

Good Afternoon girls and boys,

We are embarking on a new lesson that is a continuation of the whole chapter so far.  We are still identifying the Terms, Coefficients, Constants, Variables, but we are adding LIKE TERMS.  Like terms are terms that have the same variable and the same power.  Example- -8U-6+-6U  you can combine both terms -8U and -6U and get -14U.  Make certain that you can define all these terms with definitions that you understand.  In this lesson you will also be writing the expressions and simplifying them! 

Stroudwater Team had some injured kids.... Lily with a broken arm and Brayden with knee surgery!  I hope they heal fast and no one else gets injured!  

Homework: Read the blog and take 2 notes on this - Watch the videos and take notes in your graphic organizer and complete your vocabulary.

Chapter 5.4 The DISTRIBUTIVE PROPERTY

Now we are getting the first formal touch of Algebra, so hang on and let's get to it.  We will preload  with the vocabulary of the lesson..... the first word is another property or law of math and this is the Distributive Property. Just like the name implies, something is getting distributed or spread.  In algebra we use the distributive property when you have a number outside the parenthesis and you multiply this term to each term inside the parenthesis.  You can also think of this as the number outside tells you how many groups you have of the terms inside the parenthesis. So 3 (A + 6 ) means there are 2 groups of A+6.  We will work on this through the examples and in class, so if you still have questions, ask away. We are also looking at equivalent EXPRESSIONS.  This is where we will be simplifying the expressions.  Again, watch the videos and ask questions in our review tomorrow morning.

Homework: Read the blog- record 2 facts from it.  Watch the videos and take notes in your graphic organizer- Complete your VOCABULARY with understandable definitions and examples for the lesson on Distributive Property.

Lesson 3 Properties of Operations

Now, to lesson 3, Properties of Operations. 

Properties are like the rules of the math game.  You must follow them to get the correct answer to your problem. You are fairly familiar with some of these properties already, so they will be a review.  There are a few new rules, so make sure these get written into your graphic organizers with a definition that you understand.  And one of the basic properties is not mentioned in this lesson, but we use it the most frequently is the Order of Operations!  Many of you use the "Please Excuse My Dear Aunt Sal" to remember what operation you solve first when you have a string of operations in an expression or equations.  

You must add this Property as well as the other ones mentioned in the videos.

What a talent he has.  

Homework: Read the blog carefully and pull out 2 facts and enter them in your graphic organizers.  Watch the videos and take notes and complete the vocabulary with definitions you understand for this lesson on Properties.

Chapter 5 Lesson 2 SEQUENCES

Good day to all of you,

We are moving onward to the second lesson!  To start off, we will look at the vocabulary terms for this section.  The first word is sequence. And a sequence is ordered list of things or numbers - or pattern.  An arithmetic sequence is a pattern of numbers and you are able to find the rule to get the next number.  These 2 vocabulary terms are useful, but they are not required to be in your vocabulary list in your ribbon books.  On the other hand, the vocabulary term, TERM, is..... heeheehee..  Term in the lesson is the numbers and variables in a algebraic expression.  I learned this by counting the number of positive and negative signs in an expression- EX: -4X + 8     -4X and 8 are both terms.  This vocabulary word is required to be defined in your graphic organizers.  

Now onto the videos.....

Ohhhh my o' my........ such sweet fluff.  This little guy is going to be Leah's new puppy!!! I'm in love!!!!!!!

Homework: Read the blog, watch the videos and take notes in your graphic organizer PLUS complete the vocabulary terms for this lesson on SEQUENCING....

Chapter 5 EXPRESSIONS

Good Day to all,

We are moving on with EXPRESSIONS!  And you all know what an expression is right?  An expression is  a math sentence that generally is used when you are talking about algebra.  Expressions and equations are similar but the expressions have no equal = sign where the equations do.  In algebra, a variable is a letter or symbol that stands for a number.  This VARIABLE is what you are solving for and most often it is a letter.   If we are in algebra, then this whole sentence is called an algebraic expression- makes sense right?  We will also be learning what a COEFFICIENT is- that is the number stuck to the variable.  Then the last vocabulary term is a constant.  A CONSTANT is another number in the algebraic expression, but this number stands alone.  Make sure that you have these definitions down so they make sense.

Homework: Read the blog- write down 2 facts from it in side your graphic organizers.  Watch the videos, take notes in your graphic organizer and complete the vocabulary in terms that you understand for Chapter 5 - Expressions
