Chapter 2.4 Percent EQUATION 7. RP. 2 2c 3 7.EE.3

Good Evening Ladies and Gents,

So we are moving on with Percent Equations - and this says itself also- you will be working with percents and equations.  Make sure you check out the chart on p. 130 in your textbook and copy this down in your graphic organizer. You may need this for your test! 

You are still working on solving percent problems but in another way.  I am really not to particular in which manner you use to solve a problem AS LONG AS YOU SHOW YOUR WORK or EVIDENCE of your solutions.  So, with that being said, watch the videos on this method.  Note: I made a mistake on the answer for example 1- it should be 18!  Oops!

So, these beauties are just stunning!  Andrew has the honor of keeping them in his home!

Homework:  Read the blog, watch the videos and take notes in your Graphic Organizer on Lesson 4 Percent Equations!

Chapter 2.3 Percent PROPORTIONS 7.RP.3

Good Evening to all and I am hoping that you are enjoying your extra day off from school this weekend to your fullest!

In math class we are moving onward with the 

Percent PROPORTIONS (equivalent fractions where one fraction is a percent).  We are going to use what we learned from chapter 1 on proportions  and combine it with the percent information we know and love!  I bet that is just a thrill for all of you! So hang onto your seats and listen to the videos and take notes in your graphic organizer.  Please bring in any questions you have.

Chapter 2.2 Percents and Estimation

Hello Ladies and Gentlemen, 

It's Mr. Garbe! Tonight you will be learning lesson 2.2, estimating the percent of a number.  There are two standards connected to this lesson. They are 7.RP.3 and 7.EE.3. 

There are two things that you have probably already learned that are highlighted in this lesson. They are estimating and rounding. Do you remember what estimating and rounding mean? Estimating is making a rough or approximate calculation. Rounding is when you slightly change a number to make a calculation more simple. But why would we ever estimate and round in math if we want an exact answer?
 In the real world, you will estimate all the time. For example, when you are shopping for new clothes and find that a $52.50 pair of jeans are 50% off, you might make an estimation by rounding $52.50 to $50. Then you can find 50% of $50. We all know that half of $50 is $25, so you would pay about $25 for that pair of pants. If the cashier rings the jeans up to be $35, you can tell them that they are wrong! Eventually, you will be able to do some of this in your head. 

If you need more practice with rounding you can go to this website: http://www.ixl.com/math/grade-4/rounding

CHAPTER 2 Percents Standards 7. RP. 3 and EE.3

Homework for Thursday is in the google calendar also: Send in the completed Chapter 1 Vocabulary and essay in google CLASSROOM! 

Good Evening Girls and Boys,

Today we are moving on to Chapter 2- PERCENTS!!! You are most likely very familiar with this as you may use it in common conversations. Percents are in the standards of Rates and Proportions and Expressions and Equations.  

 If you are estimating these percents, it can be very helpful.  So, if think about percent of something as being around 50% - then that would be about half of the total.  If you divide up the total into quarters - and estimate the answer to see if it is reasonable- that may help in the actual computing. For Example:  if you are asked for 24% of 100, a reasonable estimate would be for the answer to be around 25.  Take a look into the videos and use your estimates and see if the answer is a reasonable one.

Chapter 1.8 SLOPE 7.RP.2 7.RP. 2b

Good Evening to all,

We are on the last lesson in Chapter 1 - you know what that means???????

In lesson 8, we are getting on with SLOPE. 

 Slope is how steep a line is.  This is important as you will be doing this throughout your school years.  Using the information from finding the constant rate of change - you are actually finding the SLOPE of the LINE!  So now we are focusing on Slope.

Watch the videos and ask questions by email or come in early.

Chapter 1.7 Rates of Change and CONSTANT Rate of Change 7.RP. 2 - 2a -2d

Good Evening,

We are embarking on a new lesson in math and that is Rate of Change and Constant Rate of Change.  This is pulling everything we have learned so far: rates - proportional rates - quadrants - ordered pairs- together.  So if we graph, and it forms a straight line- it is proportional if it passes through the origin.  If so, then that line is a constant rate of change- meaning it changes at the same amount over time and it forms a line.  Watch the videos and ask questions as this is an important concept.....

Chapter 1.6 Solving Proportional Relationships 7.RP.2 7.RP.2b 7.RP.3

Good Evening to all,

In this lesson in chapter 1, we are looking at solving proportions again but with ratios. 

 The standards are 7.RP.2  7.RP.2b  7.RP.3 .  

Proportions are equations that are EQUIVALENT, meaning they are equal to each other.  

Often time, CROSS PRODUCTS is an easy way to solve these. 

We have done something like this when we used cross products to simplify the fraction.  So follow along with the videos and take your notes in your Graphic Organizer. 

 YOUR NEW VOCABULARY WORD is CROSS PRODUCT! 

 Make sure you define this with all the other vocabulary terms.
