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.....

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!

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.

CCSS.Math.7.NS.1,3.EE.3( NQ2a) Adding and Subtracting Integers

Dear Girls and Boys,

So this is one of the MOST IMPORTANT concepts you will be learning and using from now on, you MUST really concentrate on these next few lessons. First with all things in math, all you can do as mathematicians is to add, subtract, multiply or divide - and in this case we are looking at integers (whole positive or negative numbers) .  We will start off with clumping adding and subtracting integers together.  

The vocabulary term for this lesson, is additive inverse.  This is the positive and negative number added together.  When you do, your answer is always 0.  For instance: -4 + 4 +0.  Makes sense doesn't it? 

Secondly, we will be looking at signs- positive and negative signs.  So one short cut rule is Same Signs and the second rule will be Different Signs!  So if both integers are positive- add both up and add the sign OR if both integers are negative- add both up and add the sign.  Got IT?  Major rule, so we will go over this.  

There will be a Graphic Organizer on this - does this show you the importance of operations with integers!  So, ask for your graphic organizer and I will know that you have indeed read this post! 

What a wonderful time we had on the field trip last Friday to Fort Williams and the Museum of Art.  Can you believe the great weather we had on NOVEMBER 3!!! Friends, Megan and Liv are certainly enjoying the day.

CCSS.Math.7.NS.3(NQ2a) Integers and Absolute Value

Dear Girls and Boys,

This Learning Target is on Integers, what they are and how to find them.  An INTEGER is any whole number both positive and negative.  Integers do not include fractions or decimals- only whole numbers.  For instance: -1,-2,-3,0, 1,2,3 are integers.  All integers can be found on the number line - the negative integers are to the left of 0, and the positive integers are to the right.  O is NEITHER positive or negative.   In this lesson, you will learn about ABSOLUTE VALUE.  Absolute Value is the distance from the integer to 0.  It has a unique symbol- l -2 l - rather looks like goal posts with an integer inside.  We will be working on this as this is one of the most important learning targets for 7th graders.  

Vocabulary Day for Spirit Week- We did a fantastic job!

CCSS.Math.7.3(NQ1c) Simple Interest

Good Day to all of you,

We are now on our last section of PERCENT and you know what this means? YUP.... a STRUT coming your way!  Are you ready?  This learning target is loaded, so hang on........ there are vocabulary terms to learn and when you do learn them, you are half way to solving the problems!

So let's start with the first vocabulary term- PRINCIPAL- and no, this is not Mr Riley!  When we are talking about Principal with interest, you are talking about the amount you saved or borrowed from a bank.  INTEREST is the second term, and this is the money that you owe or earned from the use of the money.  There is a shortcut formula to use when finding out the Simple Interest---

---  I = prt!

Before you get scared, lets look at this formula.  I= Interest  P=Principal  R=Percent Rate and T= Time( in years).  Using the formula, you need to plug in the correct information and solve.  I know this is still vague, but watch the videos and ask questions.

CCSS.Math.7.RP.3(NQ1c) Discount

Dear Girls and Boys,

The last learning targets were Sales Tax, Tips and Markups, where a percent of money was ADDED ON to the price of the item or service.  This learning target is when money is SUBTRACTED FROM the price- now we are talking!  In this lesson, we are talking about sales, discounts and markdowns, where a percent of money get taken off!  Don't you just love a bargain?

CCSS.Math.7.RP3(NQ1c) Sales Tax, Tips, and Markups

Dear Girls and Boys,

These Learning Targets, Sales Tax, Tips or Gratuity, and Markups maybe very familiar to most if not all of you. This is the extra money beyond the cost of the item or service that gets added onto the item as you pay.  Sales Tax is what one pays to the government. Tips are generally added onto a service, for instance: a waitress may earn a tip for good service.  This is money she gets beyond her salary.  Markups are what is added onto an item before the price is set.  The markup goes towards the cost of running a store. 

These Learning Targets are all examples of money being tacked onto the price of items or services.  The following target will be examples of money being lowered for items or services.  

This is Willa and Inzo is the kitten above.  What a cute pair. Brady is some lucky fellow to have them.
