Chapter 6 Equations- One step

Good Evening Girls and Boys,

We are moving onward to a new chapter and that is on EQUATIONS.  We will be looking at solving 1step equations!  I bet you can hardly wait for this lesson.....  First of all there are vocabulary terms that we will tackle as we need to be using these to sound like a mathematician!  The first term is Equations.  We have talked a great deal about these in prior lessons, but this whole chapter is about them. So equations are important and the gateway into algebra.  Equations have an equal sign = that splits the math sentence into 2 parts.  Both of these parts must remain equal or balanced at all times. That is your job to balance them using properties.  Think of the sentence on a balance beam.  You can take off or put on the same amounts on both sides to keep the sentence balanced.  It sounds difficult, but it is fairly easy.  The next term is Solution.  Solutions are the answers.  The next two terms are Addition and Subtraction Property of Equality.  Don't those sound impressive!  These 2 properties are what you use to balance the equations and solve for the unknown variable. Go through the videos and try to see where these properties come into play.  We will go over these and you may fill in these after the worksheets are done.

Leah is quite the photographer !  She snapped this picture of the Old Orchard Beach Pier!  What perspective! 

Homework: Read the blog.  Watch the videos and complete the vocabulary.

Chapter 5.7 Subtracting Linear Expressions

Hello to all of you out there!

This lesson on subtracting linear expressions is built off the earlier lesson on adding linear expressions.  Rather than add the two groups together, you will be subtracting them- BUT..... there is a catch!  When you subtract the second group, you are changing the sign of all the terms in that group.  Go through the examples and pay close attention to the little trick.  Remember that a linear expression is an expression that is not raised to a power.  

Best Friends, Leah and Natalie being silly today- as usual! 

Homework: Read the blog and take notes in the graphic organizer. Watch the videos and take notes once again and there are no vocabulary terms this lesson -Yippee...on Subtracting Linear Expressions.

Chapter 5.6 Adding LINEAR Expressions

Good Day to all,

Today we are learning about Linear Expressions.  What are these you ask.... Well take a second to look at the word linear.  
Do you see a smaller word in it?  Maybe line???? 
Well, math usually is that obvious, as we will be talking a great deal about Lines in the very near future, but for now the authors describe linear expressions as an algebraic expressions where the variable is not raised to a power
 and only added and subtracted from each other.  Phew!

Examples: 3x+2, x-7 are linear, but 3x^2 +2 is not a linear expression.  Doesn't that clear up all the confusion?  

Heeheehee..... remember when I asked you to look at the word, Linear and you saw Line in it? Well a linear expression is where you would get a line if you were to graph it - 
we will be doing this soon.  

Don't worry, it sounds harder than it is.  
In your graphic organizers, I want you to record 2 facts that are confusing from this blog.

And we have Gage! He's cleaning out his locker!! This is a wonderful sight to behold. Let's take a guess as to how LONG it will late being clean!!!! Heehee, Gage!

Homework: Read the blog- record 2 facts that are confusing.  Watch the videos and take notes in your graphic organizer and complete your vocabulary Linear Expressions.
