Tuesday/Wednesday February 7th-8th

posted Feb 7, 2012, 8:44 AM by Alicegop Keeler

The new math teacher Mr. Dull will be here starting Wednesday. To help him most effectively teach you he wants to know what you know.  You will take a practice test.  NO iPads, NO talking, NO help.  Do your best.  Show work demonstrating you are in a high school math class showing clear and well though Algebra processes. Use complete sentences. 

When you have turned in your pre-test please go onto Edmodo and and for assignment #4 pre test write Mr. Dull a note about how you think you did.  This is part of your assignment, make sure you complete this.

Codes are 
1st: nupwe8
2nd: d0nxgr
3rd: dgxtiu
5th: 23sglh
6th: c6r6oy

THEN you'll need new quia class codes.
Since I am a different teacher than the last teacher I have a different quia account.  You need to add my class code to your account.

1st: EFME497
2nd: DRC863
3rd: XDDRJ934
5th: HPCXFG846
6th: KBK636

Your instructor requests that you enroll in the following class: 

  Class: 1st Geometry 2011-2012
  Code: EFME497

Step 1. Go to the Quia website at 

Step 2. Now, click the area labeled Students. When the next page appears, enter your username and password if you already have a Quia account. If you do not have an account, click the link Create my free account. Fill out the form that appears. Select "Student" as the account type. When you are done, press the Create my account button. 

Step 3. You should now be in the Student Zone. Type in the class code EFME497 in the text field and press the Add class button. Now you're done! 

Now that you have registered for your instructor's course, you can view your class web page, take quizzes, view your quiz results, view time spent on Quia activities, and read your instructor's feedback from your Quia account. 

Follow these steps to view your results: 

Step 1. Log in to your account. (Remember, go to the Quia Web home page at and click the area labeled Students.) 

Step 2. Click on the class name.

You should complete your assignments on Edmodo.
When you are done work on this Quia activity for Mr. Dull:

For some of you this will be our last class together :(

I am looking for evidence that you have mastered the Geometry Standards.

On quest #71 you were suppose to get 80%, but really I would like you to get 80% or better multiple times.  So keep working on it!
Need at least 80% on this activity.

#65 Start a blog post titled "More Congruent Triangles"
Make a list of the rules that work for congruent triangles

Go to Google Images ( and do a search for congruent triangles, ASA, SSS, SAS, AAS. Get pictures of these types of triangles (hold finger down and save image) and insert these into your blog post.  For each picture say what kind of congruence is shown (ASA or SSS, etc...)
I want you to find more than one picture of each type of triangle congruence. Show me that you can tell the difference between ASA and SAA. Make sure you label each of them.

Then find some pictures that would indicate no good (stop signs, guy getting sick, etc...) to bring your attention to the next things you will include in your blog post.  
That SSA and AAA are NOT enough evidence to prove triangles congruent. 
Include pictures of these in your post as well.  Find pictures that show AAA triangles that are similar, have the same angle measures, but are clearly NOT the same triangle (one bigger or smaller).  Find pictures on google images of SSA triangles that have 2 sides and an angle the same but are not the same triangle.  
Notice in example A that both triangles have 2 sides and an angle in common, but that they are NOT the same triangle.  So SSA does NOT prove the triangles are congruent.
In example B both triangles have 3 angles in common but again are NOT the same triangle.  So AAA does NOT prove the triangles are congruent.

#66 Do these quia activities to practice congruent triangles
Post screen shots from your playing and also your results. 

For this activity you should cheat.  (seriously). Most of it you do not know. I do NOT expect you to get a good grade on it.  Get the answers from classmates, look up on the internet.  Take the test, get all the answers and then take it again. The better your score the more XP I will get you.   As always post pictures to your WP blog of questions along with your results. 

If you can become a millionaire on this activity make sure you put in the "Evidence of Mastery" box on the turn in form "I GOT THE BONUS, GIVE ME EXTRA POINTS" and of course include screen shots on your blog :)
