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! 

This is Brooke and her horses.  I guess you can say this young lady loves her horses.

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.

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!
