Good Day to all of you,
This lesson is about change, Percent of Change. What do you think of when you use the word CHANGE? Is it, you start with something and then that changes into something else?? Well, in Percent of Change, you are talking about the original amount and the amount that it changed to as a ratio. This change can be a decrease or increase. There are shortcuts, formulas, that you can use to solve these percent problems. You can use these formulas to find out how the price of gas has changed over a period of years, how much the price changed for any sales item, or many other items that can change. If the change goes down, you would find the Percent of Decrease. And if the change goes up, you would find the Percent of Increase. And if you are estimating, the change in the actual and estimated amount is the Percent of Error.
So, there are 3 formulas to help out with the solutions to each type of problem. Make sure that you look over the key concepts on pages 144 and 145.
You must write down 3 facts from this blog into your graphic organizer.
These are Catherine's little sister and nephew. They sure are sweeties!
Homework: Read the blog, watch the videos and take notes in your graphic organizer, and complete your vocabulary terms.
As always in MATH,
Mrs M
