Topics/Areas to Study for Final Exam

The SBA's, which were supposed to be given next week, have been moved to the first week of June.  Instead, final exams for 7th grade will be given next week.  Here is a link to the topics which will be on the final. You can download the document to see what areas you need more work on. 

We will only have time for a very few questions from each area, so make sure you ask if you are not sure how to do some of the problems. 

The exam review will take place Wednesday-Friday of this week, and Monday of next week.

Do You Have Triskaidekaphobia?

You might have Triskaidekaphobia and not even know it.  If you think you might have it, you should really have it checked out.  It might cause you to miss school today.

Send me an email, and tell me what Triskaidekaphobia is. If you're one of the first three, you got yourself a free hour of computer time.

For those of you who have free computer time, you've got just two weeks to use them. So don't forget to tell me "No work now, Mr. Ferrari, I'm going to use my computer.

Weekend Tips: Online Storage & More

Maybe you know someone whose computer has crashed already; possibly that person is you.  Nothing is worse that having your computer crash.  Even though there are other, harder ways to save your data, most computer shops will fix your computer by wiping your hard drive clean and starting over.

The result: You lose all of your data. Pictures, programs, documents, grandma's secret pig's feet recipe. Gone. All of it.

Here's the thing: You never know when it is going to happen. It's happened to me, it's happened to everyone who's used a computer for a while.  So, be smart, be free, and do it for free.

There are many places where you can store between 2 and 50 Gigabytes of data for free. If you have anything on your computer you don't want to lose, create an account, upload all your stuff, and never worry about a computer crash again.

An added bonus is that you can create public and private folders. If you have some pictures you want to share, upload them to your public folder and give people the web address. They can get the photos, documents or whatever themselves.  No more flash drives, dragging things around. Clean and easy.

Here are some links to online storage sites:  ADrive, OpenDrive, Flickr,   and finally, don't forget about Gmail. If you have an account, you have 7 gigabytes of storage. You can add anything as an attachment and upload it. There is no public folder with Gmail, though.

 Don't learn your lesson the hard way. Get an account, upload the things you don't want to lose, and sleep well at night.

Quick Tip #2:

If you're leaving your computer for a few minutes and don't want anyone messing with it, you can quickly and easily lock the keyboard by pressing the Windows key and the L key. Win + L. Just takes a second, and your computer is secured.

Test Prep: Stem & Leaf Samples

Try working these problems before checking the answer. It will go fast and you'll be better prepared for tomorrow.

First, draw the stem and leaf for the following data:  30, 43, 25, 18, 8, 14, 37
Before plotting the data on the stem and leaf, arrange the data from least to greatest.

After putting the data in the stem and leaf, find the mean of the data.

Then find the median.

Finally, find the mode.

Stem & Leaf Sample 2: 
For this example, you only have to place the data in the stem & leaf.  Here's the data:
117, 109, 123, 85, 102, 127, 215, 136

After doing the problems, the answers can be found here.

Don't forget to check the previous post for sample mean, median, and mode questions.


Good Luck, see you tomorrow.

P.S. I'm still working on the Super Teaser, give it a day or two at most.

Test Prep: Mean, Median & Mode

Here's a quick review for tomorrow's test. Try to work the problems before checking the answer.

Mean:  First, Sum all of the data, then divide by the number of items in your data.  For example: You are asked to find the mean of 6,10,5,7,6,8,.  Try working the problem now. Add up the numbers and then divide by 6, the number of data points.  Go ahead, work it, I'll wait.

Here is the answer:

     Sum = 42, divided by 6 = mean of 7     Press and highlight the blank area before the sentence to view answer.

Median:  When finding the median, you must first place the numbers in order from least to greatest or greatest to least. Using the same numbers above, they are rewritten 5, 6, 6, 7, 8, 10. The median is the number in the middle. If you have an even number of data items, like we do here, add the two middle numbers and divide by 2. Go ahead, find the median..

   6 + 7 = 13 /2 = 6.5  Once again, highlight the area before this sentence for the answer:  Did you get it correct?

Mode: The mode is simply the number that appears most often, the most common number. For our numbers, 5, 6, 6, 7, 8, 10, the mode is, what? Did you get  6  for the mode?  Hope so.

Check back a little later tonight for Stem & Leaf examples, gotta go walk the dog now.

Photo History

Maybe you need a picture for a report, or maybe you just like looking at old photos. If so, you'll want to check out historypin. There are hundreds of pictures from around the world dating all the way back to 1840. (That's 170 years ago).  If you're curious, and have a little time to kill, it's worth a few minutes.

                                                                  Shopping, 1870

                                                                 New York City, 1875

Talking with Skype

Many of you are familiar with Skype already.  Skype is a program that sends two-way voice and video over the internet.  What this does is lets you have a video chat with anyone anywhere in the world for free.

Do you have friends or relatives living off island?  No need to spend another penny on long distance calls. As long as they have Skype installed on their computer, you can talk and see each other. No time limits, no charge.

After downloading Skype, link here,you give yourself a username. Once your user name is set, just give it to those you want to talk with. If they call you, your computer rings just like a phone. Click on the phone icon (picture) and say hello.  A great program for those who have others far away.

P.S. A new Super Teaser coming tomorrow. More great prizes. Very, very few will enter, all of them will win.

In 20 Years

Has anyone checked out that website I posted a while back called in20years.com.  In case you haven't, you upload a recent picture of yourself, and it shows you what you will look like in 20 years. You can also choose to see what you'll look like in 30 years if you really want to get depressed.

This site is not cool at all.  I uploaded a picture of myself and chose to see what I'll look like in 20 years.  This is the picture it came back with:

Not funny, man.

Lots 'O Fonts

                     Fonts,  Lettering Styles.
They can add a lot of personality and pizzaz to a document. Fonts can also add a personal touch, such as fonts for holidays, birthdays and other themes.

There are lots of free fonts on the internet which you can download for free.  A couple of the best sites for lots of free fonts are 1001 fonts and DaFont.com.

How to install fonts:   After you have downloaded the font(s) you want, the first step is to unzip the folder. Right click on the folder and select unzip. ( If you are using 7-zip, select "extract to "name of font".  Next, double click the unzipped folder. Right click on the font, and select "install". That's it, the font should be installed in the correct folder. You can then delete both the zipped and unzipped folders if you like.

Caution I:  Don't download fonts unless you think you are going to use it. When a program that uses fonts loads up, (like Word, Open Office, and others,) it loads all the fonts at the beginning.  Having tons of fonts will just cause the program to take longer to load.

Caution II: Please dont' use crazy, hard to read fonts for school reports or other important documents you may write. These fonts aren't really for those types of documents.

Otherwise: Download, Install, and Enjoy

Fax Me a Sandwich, No Mustard Please

Well, that may not taste too good right now, but technology is always changing, so you never know. Because technology is becoming a bigger part of our lives, it's important that you are always learning and trying new technology when it comes out.  If you shy away from it, or don't feel like learning the "new stuff", you will just fall behind while others move forward.

For example, have you seen the new cell phones by Samsung?  Here's a picture of it. The keyboard is displayed through laser light, and is connected to the phone using Bluetooth ( a short range wireless connection).

But with new technology like this, you have to learn new programs, things like how to print, save, send files, etc.  Grab it, learn it, and don't shy away from it.  If you do, you'll be way ahead of those that don't learn it. Better job, more money, more toys, all that stuff, just from taking the time to always learn the new stuff.

We Lost Our Dog; Have You Seen Him?

After school today, we noticed that our family dog Buster was gone.  We're not sure what happened to Buster, but if you do see him, we're asking if you could take him in for the night and then let me know tomorrow at school.  Buster loves Pizza with lots of toppings and always sleeps on the bed. I hope somebody out there finds him.

Scroll down for a picture of Buster:

Step-By-Step Guide to Rotations

There are three types of rotations, so you need to remember three rules. We will do one example here. A rotation problem might be something like this:

Graph the image of the figure after a rotation of 90°clockwise:

 

 Step 1: Write the coordinates of the given figure.  The coordinates are: M(1,0), N(3,2), O(4,-1) P(3,-3)

Step 2: Use the rule for rotating 90 degrees clockwise. Check the bottom of Page 508 for this. (I'll wait.....)

The rule is, switch the coordinates, then change the sign of the second number.

Step 3: Write down the new coordinates.  The new coordinates are: M(0,-1), N(2,-3), O(-1,-4) P(-3,-3)

Step 4: Plot the new coordinates and draw the new figure. Like this:

You still need to know the rules for counterclockwise and 180 degrees.

Step 5: the..the..the..that's all folks. Study. 

.

.

.

Step-By-Step Guide to Reflections

There are two types of Reflections, so there are two rules you need to remember. A reflection problem might say something like:

The vertices of figure JKLM are J(-4,-2), K(-2,-2), L (-1,-4), M (-5,-4).   Graph the figure and its image after a reflection over the Y-axis.

Step 1: Plot the coordinate points and connect the dots, like this:

Step 2: Since we are reflecting over the Y axis, we need to know the rule for this.  (Checking page 508, top)...Here it is:  The Y coordinate stays the same, and we change the sign on the X coordinate.  The new coordinates are:

J(4, -2), K(2,-2), L(1,-4), M(5,-4)

Step 3:  Plot the new coordinates, and draw the new figure. Like this:

For a reflection over the X axis, check the top of page 508 and know that rule, too.

Step 4: Go to the next problem

Step-By-Step Guide to Translations

When you translate a figure, you simply move it to another part of the graph. A translation problem might say something like, 

Triangle RST is shown on the coordinate plane. Find the coordinates and graph the image if triangle RST is translated (-6,-3).  Here is triangle RST:

Step 1: You must write down the coordinates of triangle RST.
The coordinates are: R (3,3) S (4,1) T (2,-2)

Step 2:Move each point 6 units left (-6), & 3 units down (-3). 
The new coordinates are: R (-3,0) S (-2,-2) T (-4,-5)


Step 3: Plot the new points, and draw the new figure. Like this:

  Step 4: Go to the next problem

Did I Mention Page 508?

Page 508 of your handout.  Everything you need to become rich, famous, and powerful is on page 508.  Read the top of the page and the bottom of the page. Memorize those five rules...before the test tomorrow.

Do it... Now
