Ancient Greek Computational Thinking - ERATOSTHENES | Teaching London Computing: A RESO... - 2 views

  •  
    "The Ancient Greeks loved algorithms, and devised lots of useful ones. One of the most famous is the Sieve of Eratosthenes. It is a way to find prime numbers, special numbers that are also known as the atoms of numbers. Prime numbers now form the basis of our most powerful encryption systems upon which digital money is based. Our electronic banking systems (and lots more) would collapse without prime numbers. You can use the Sieve of Eratosthenes as a way to practice times tables, spot patterns and explore how to improve algorithms, whilst also uncovering these mysterious, magical numbers with no obvious pattern of their own. Here you can follow in the footsteps of Eratosthenes and develop your algorithmic thinking skills."

Pi Day history: Perfect symmetry, a mathematical constant, wave formulas, and pie. - 0 views

  •  
    "There are holidays like Mother's Day, Earth Day, Thanksgiving Day. Even a Talk-Like-Shakespeare Day. But Friday is Pi Day. Really! It's official. The date March 14 (that is, 3/14) was designated Pi Day by House Resolution 224 of the first session of the 111th Congress of the United States. It begins "Whereas the Greek letter (Pi) is the symbol for the ratio of the circumference of a circle to its diameter," and is followed by 11 more whereases before it resolves to support the designation of "Pi Day" to encourage "schools and educators to observe the day with appropriate activities that teach students about Pi and engage them about the study of mathematics.""

6 Factors Of Gamification That Changes Students - 4 views

  •  
    "I was 11 the year my summer camp director transformed the regular schedule, procedures, and lingo that we were used to-into the most memorable, enriching experience I had ever encountered at that point in my life. I had no idea that he had 'gamified' the week; I just knew that it was the best summer ever. Instead of grouping us by numbers, we were named after the Greek alphabet. We competed daily against the other groups in volleyball, softball, kickball, and on the final night -a chariot and Olympic flame opened an epic Olympic Game contest at midnight. The director, or 'game master' as we were inclined to call him, even made everyone reset the clocks and watches-so we never knew what the real time was, the entire schedule was set on some sort of crazy alternate schedule. Now I realize that it probably allowed him to sleep in and us to stay up later, but we were none the wiser. Daily we played games, wrote skits, went swimming, and competed for cleanest cabins. We did all the regular stuff, but it was more fun because there were rules and boundaries and points and collaboration and competition and a clear, mutual understanding of goals and performance and criteria for success. As a student, I got to learn more about the power of 'gamifying' something, and what effect it had on learners."

What is Haptics? - 2 views

  •  
    "The origin of the word haptics is the Greek haptikos, meaning able to grasp or perceive. Haptic sensations are created in consumer devices by actuators, or motors, which create a vibration. Those vibrations are managed and controlled by embedded software, and integrated into device user interfaces and applications via the embedded control software APIs."

A Stunningly Simple Way To Explain Pi - 2 views

  •  
    "So there's that-which brings us to the above animation shared by reddit user merelyhere that brilliantly illustrates the significance of "pi." Pi is the often-referenced mathematical concept that students may be able to quote to ten digits or even use to solve formulas, but otherwise simply don't get. The Wikipedia definition for pi is the "number π is a mathematical constant, the ratio of a circle's circumference to its diameter, approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century though it is also sometimes spelled out as "pi" (/paɪ/).""

3 Interactive iPad App-tivities that aren't Apps! « techchef4u - 1 views

  •  
    "As I mentioned in a previous post, I am always intrigued by sites that offer interactivity but are not apps (ala Quizlet). I had observed Mr. Wayment's class reviewing the Greek & Latin roots using an 82 card Quizlet deck he had created. Students were utilizing various activities within Quizlet (e.g. Speller, Learn, and Scatter) to review the terms."

How to Type Accents on Mac the Easy Way - 3 views

  •  
    "Many languages use accents and diacritic marks to change how a letter or vowel sounds. Accordingly, you may find it useful to know how to type accents and diacritical marks on a Mac using the keyboard. This should be particularly useful for users who also type or write in Spanish, Portuguese, French, and Greek, but obviously this applies to many other latin language scripts as well. Modern versions of Mac OS offer an exceptionally fast way to type letter accents, and it's quite easy to use. "
