Chapter 2.5

Hello, 

Welcome to the second half of Chapter 2!!! We are now entering the other side of the chapter....

and this is PERCENT OF CHANGE.  

Does this sound familar from Chapter 1?  I hope so because math builds on itself and here is an example of that.  So, when we look at change - we do just that- look how something changes!! (Haven't I always said that "math says itself"?) 
So, we are looking at the change from one thing to another. Either that is a change that increases the number or decreases the number, but it can't stay the same.  

Another thing from Chapter 1 is the percent of change is a ratio(FRACTION) that compares the change to the original amount.

PERCENT of INCREASE

amount of increase

original amount

PERCENT OF DECREASE

amount of decrease

original amount

PERCENT OF ERROR

amount of error 

actual amount

So, this seems difficult and I ask you, "Where will I use this or when will I see this? "

AND my response to you would be - this is one of the most practical parts of math! Have you ever heard your parents talk about gas prices and how much they have gone up(CHANGED) from last year? Well, this chapter is the one for you! Dig right into the videos and enjoy! Email or comment to me on an example of something that changes?

HOMEWORK - Read this blog and watch the videos as often as you need to. 
 Could you write up your own problem using Percent of INCREASE, DECREASE or ERROR?????
