CCSS.Math.7.EE.1,2.NS.3(NQ.1a,1b) Expressions

Dear Girls and Boys,

We are moving onward to a new STANDARD- EXPRESSIONS and EQUATIONS. This will mean that when you look into Infinite Campus, you will need to change tabs to Expressions and Equations to see your grades.

Expressions are really Algebraic Expressions- see, you already sound smarter!!! Lol

Algebraic expressions are is an expression that contains a variable.  A VARIABLE is a symbol that stands for a number.  An algebraic expression has a variable and at least 1 operation(+ - x /).    

In algebra, often times, the multiplication signs are omitted. For instance: 6d is 6 times d; 9st is 9 times s times t;mn is m times n; and a ^2 is a times a.  The other important vocabulary terms  are : COEFFICIENT: a coefficient is a number that is attached to a variable :6x - 6 is the coefficient , and CONSTANTS: these are numbers that stand alone: 6x + 3- 3 is the constant.

  To summarize:  an equation has a variable and at least one operation.

Coefficient- is the number that is attached to the variable.

Constant is the number that stands alone.  You must be very familiar with these terms and use them in class.

CCSS.Math.7.NS.2,3.EE.3(NQ.2c) Rational Numbers- Multiply/Divide Mixed Numbers

Dear Girls and Boys,

We are moving on with multiply and divide with mixed numbers.  Mixed Numbers are rational numbers as they are whole and fractions combined.  We have looked at adding and subtracting in the previous lesson, and I do believe they are harder than multiplying and dividing mixed numbers.  With multiplying/dividing mixed numbers you do NOT need common denominators so it is one step less in solving.  Dividing has Special STEP- where you use the RECIPROCAL to solve- a reciprocal is when you flip the fraction around- so the numerator is now the denominator!  Hang on and watch the videos and be prepared for the vocabulary quiz coming soon to a classroom near you!

CCSS.Math.7.NS.1-3.EE.3(NQ.2c) Rational Numbers - Add/Subtract MIXED NUMBERS

Dear Girls and Boys,

We are moving on with our review with adding and subtracting fractions, but with a twist of adding on the negative rules with them.  With all fractions in addition or subtraction, you must have common denominators!  Remember a Rational Number are all whole numbers, all fractions and some decimals - those that end or repeat, both positive and negative!  I believe you will find this section fairly easy and remember your negative rules.

This little black beauty belongs to Andrew and she sure looks like she wants some to play catch with her!

CCSS.Math.7.NS.1.3.EE.3(NQ. 2c) Rational Numers - Add & Subtract Unlike Fractions

Dear Girls and Boys,

We are mostly reviewing what you know about fractions! Yay, but we will be adding on the Negative Rules!  Just as I promised, Negative Rules RULE!  

In adding or subtracting fractions, you must have Common Denominators or LIKE denominators. Like means the same size, and Unlike means different size.  I am sure that you remember how to make COMMON Denominators, but this will be reviewed in the videos as well.  What makes this at a 7th grade level is that we are including the negative rules.  

EXTRA CREDIT:  I challenge all of you to make up a rap, jingle, or a sing-song that covers all of the NEGATIVE RULES as well as have it video taped complete with lyrics.   Yes, you may work as partners!  Have fun with this!  

This is Liv's Puppy.  He is soooo cute.  Bet he gets lots of attention from all who meet him!

CCSS.Math.7.NS.2.EE.3(NQ.2c) Rational Numbers-Comparing and Ordering Numbers

Dear Girls and Boys,

We are still working with Rational Numbers- all whole numbers (+ - ) and all fractions ( + - ) and some decimals ( those that terminate or repeat +  - ).  We are also applying the NEGATIVE RULES with these numbers as well. In this lesson we will be looking at Rational Numbers and comparing or ordering them. That generally means in math terms, which number is larger or smaller.  We are working with fractions and decimals, so this should be a review other than we will be applying the negative rules to these.

So pay attention and practice practice practice.....

These sweet little pups are from MJ's dog!  Oh my oh my...... how darling!

CCSS.Math.7.NS.1-3(NQ.2c) Rational Numbers

Dear Girls and Boys,

We are using all of the information from Integers and bringing it forward to Rational Numbers!  Rational Numbers are extensions of Integers.  Integers are all whole numbers both positive and negative, and Rational Numbers are Integers PLUS all Fractions and some Decimals. So, Rational Numbers are all numbers, whole, fractions, and some decimals that end AND this means both positive and negative numbers as well.  A lot to swallow, but hang in there, we will be learning this step by step.  We will be starting this lesson with TERMINATING and REPEATING Decimals.  Terminating means to end and Repeating means there is a pattern! Make certain to learn and use the vocabulary - Integers, Rational Numbers!

These little bonded kitties were at the Animal Refuge League a few weeks ago.  If you are looking for a pet, check out the ARL.  Olivia was there and fell in love with these furbabies, but she can't adopt for a little while!

CCSS.Math.7.NS.1-3(NQ2a) Subtracting Integers ( Triple Signs)

Dear Girls and Boys,

Now that you have a feel that all numbers have a sign attached to them, I hope you can see or understand that some numbers - integers - don't actually have signs.  Some positive integers do not have a sign, but they are assumed to be positive. 

All negative numbers have their signs.  

Another major idea is that positive, adding, more than, etc.... are all the same.  And negative, subtracting, take away, etc.... are all the same too.  Mind blowing right?  

In these lessons, you will be looking at the signs of the number - they are either both the same (- -) or (+ +).  With the same signs, there are 2 rules - add the digits and add the sign.  Well, we are embarking on 3 signs!   These are used VERY FREQUENTLY, and are also very important- they will be entered on your Grapher Organizer as well.....

In this section of Triple Signs, there are still 2 rules to follow to solve problems.  Make sure you watch the videos and ask questions. 

As always in MATH,
