CCSS.Math.7.RP.3(NQ1c) Percent of Change

Dear Girls and Boys,

We are moving onward with Percent of Change.  Math often times names things as they are.... in this case, Percent of Change is where we will continue to work with Percent - divided by 100- but this time we will be looking at how things change- meaning: going up or down.  For example:  If there is a sale going on( my favorite time to shop), the price with go down after a certain percent it taken away.  This is Percent of Decrease! And the opposite: If I buy something at the store, I will have to pay more due to sales taxes. This is Percent of Increase!  There are formulas to help solve these, and I am thinking that you will catch on fairly easy as it is a very common thing to work on.  The third part of this lesson is Percent of Error.  This is the difference between the guess and actual amount.  It is figured just like Percent of Increase and Percent of Decrease.  Hang on, watch the videos and ask questions.  

Ask questions and come to class prepared to learn.

CCSS.Math.7.RP.3(NQ1c) The PERCENT EQUATION

Dear Girls and Boys,

Homework: Read this blog carefully, watch the videos and take notes in your video notebook.  

Today's lesson is on solving equations again, but this time, we will be using the PERCENT EQUATION.   This is just another way to solve for an answer using percents.  The Percent EQUATION is part=percent(whole).   You will have practice problems solving these in class, but please feel free to ask questions.  You will be asked to COMPARE and CONTRAST the difference between Percent Equation and Percent Proportions, 

so think about this soon.  

The next "Strut Your Stuff" will be on TUESDAY!!!

CCSS.Math.7.RP.3(NQ1c) Percent Proportion

Dear Girls and Boys,

Homework: Read this blog, watch the videos and take notes in your video notebook.  

We are moving on with solving percent problems by setting them up as proportions( remember that proportions are similar to equivalent fractions!).  On page 122 in your textbook is a handy table that may help you set these problems up.  With fractions, you have the whole as denominator and the part as the numerator

 - for example: There are 5 parts of the pie and I ate 2. 

 This would be set up  as 2/5. 

Part/Whole is how we will be looking at fractions now, as well as the percent will also be written as a fraction - for example: 39% = 39/100.  This sounds confusing, but hang on as you will be using these in class practice.

CCSS.Math.7.RP.3(NQ1c) Percent and Estimation

Dear Girls and Boys,

Today is a new day to learn math.  You are so lucky!  We are building on with percents( divided by 100) but adding in ESTIMATION.  In my humble opinion, being able to estimate makes your life so much easier and in this lesson you will be using your estimation skills to.  Have you ever tried to estimate your total amount you spend at a store so that when the cashier gets the total, you are not surprised ? I try to out do my husband when we shop as to who is the closest at the checkout....... 
do you ever challenge others?

CCSS.Math.7.RP.2c.EE.3(NQ2a). Percent of a Number

Dear Girls and Boys,

Homework: Read the blog, watch the videos and record in your video notebooks.  Pay close attention to the vocabulary and learn to use it when talking math!

We are moving onward to Percent. We are still in the Performance Indicator of Rates and Proportional Reasoning though.  
I am certain that you have heard about percents when you see something on sale, or pay at a cash register and have to pay the tax, or even if you have been to a restaurant and had to pay sales tax and a tip to the server.  
 In these lessons, we will learn how to solve percent problems that are all around you!  

Examples of percents are 5% 2.5% 100% -  Percent is dividing a number by 100.   In these lessons coming up, you will be working back and forth between PERCENT=FRACTIONS=DECIMALS. As in all subject areas, math has a vocabulary as well.  Once you have the vocabulary down, the rest is a bit easier!

CCSS.Math.7.RP.2b(NQ3). SLOPE

Dear Girls and Boys,

Homework: Read this blog, watch the videos and take notes in your video notebook.  We are having a "STRUT YOUR STUFF" assessment on THURSDAY from lessons 1.5- 1.8 - proportions to slope! ASK QUESTIONS!  There will probably be a vocabulary quiz as well.  

We have finally made it...... to SLOPE!  You probability have heard of slope of the line and even if you have not, you will learn more about a line than you could possibly ever want to know!  Well, slope is a line that is measured by how steep it is.  A textbook definition will define slope as the ratio of the change in y-value over the change in x - value. I think this is totally confusing.  And slope can be confusing as it uses the y first and then the x- where ordered pairs are ( x,y) where you use the x first and then the y. Are you confused yet????? Well, when I think of slope, I think of steepness- and this is the y ( y goes up and down or the rise up and down ).  So, in slope, you are doing the 

RISE over the RUN  - Rise/Run.  

Slope =Rise(y) / Run(x)
