"New York pop artist Michael Albert is best known for his “pop cubist” cereal box collages. Michael's unique style was born one day when he decided not to throw out an empty Frosted Flakes cereal box, and to see what he could make of it instead. From that day forward, he has diligently gathered the symbols of commercial America that surround us, and turned them into a series of collages with a wide array of themes. One of them is, of course, the number Pi." From http://www.teachpi.org/links/poster.htm. Check out the website for all things Pi, from stories to songs!

WE REMEMBER
As you enjoy your long weekend, take a moment to read this story and reflect on why you have Friday off.
Back in September, on the first day of school, Martha Cothren, a social studies schoolteacher at Robinson High School, did something not to be forgotten. On the first day of school, with the permission of the school superintendent, the principal and the building supervisor, she removed all of the desks out of her classroom.
When the first period kids entered the room they discovered that there were no desks.
'Ms. Cothren, where're our desks?'
She replied, 'You can't have a desk until you tell me how you earn the right to sit at a desk.'
They thought, 'Well, maybe it's our grades.'
'No,' she said.
'Maybe it's our behavior.'
She told them, 'No, it's not even your behavior.'
And so, they came and went, the first period, second period, third period. Still no desks in the classroom.
By early afternoon television news crews had started gathering in Ms. Cothren's classroom to report about this crazy teacher who had taken all the desks out of her room.
The final period of the day came and as the puzzled students found seats on the floor of the deskless classroom, Martha Cothren said, 'Throughout the day no one has been able to tell me just what he/she has done to earn the right to sit at the desks that are ordinarily found in this classroom. Now I am going to tell you.'
At this point, Martha Cothren went over to the door of her classroom and opened it.
Twenty-seven War Veterans, all in uniforms, walked into that classroom, each one carrying a school desk. The Vets began placing the school desks in rows, and then they would walk over and stand alongside the wall. By the time the last soldier had set the final desk in place those kids started to understand, perhaps for the first time in their lives, just how the right to sit at those desks had been earned.
Martha said, 'You didn't earn the right to sit at these desks. These heroes did it for you. They placed the desks here for you. Now, it's up to you to sit in them. It is your responsibility to learn, to be good students, to be good citizens. They paid the price so that you could have the freedom to get an education. Don't ever forget it.'

I will be disabling "Anonymous" comment-posting on the blog due to serious inappropriate comments being left on here. This website is meant to be a learning and communicating resource for students and parents. Students with concerns should bring them up directly with the teacher, rather than hide behind the irresponsible, immature, cowardly mask of online anonymity. I welcome any questions related to class on the blog, but from now on, you will have to sign in with a Google account (i.e. Gmail) and include your name in all comments. In other words, you will be accountable for anything you post on here. It is unfortunate that this is the route we have to take, as I do understand that sometimes students feel more comfortable asking (appropriate) questions anonymously; unfortunately, however, certain students have taken advantage of this comfort and used it for derogatory comments which are harmful to everyone involved.
I do want to thank the majority of students who have been using this blog according to its purpose :)

Convenience Store
Mario went to a convenience store and selected a package of chocolate bars for $3.16 (tax-free). He then added three other tax-free items to his basket. Mario calculated the total of all four items to be $7.11. The clerk used a calculator to determine the total to be $7.11 also. Later, when Mario checked the receipt, he noticed that the clerk had multiplied, rather than added, the four prices. What were the four prices?
