Theconversation. Most people have heard of the mathematical constant Pi (π), and will know that it’s roughly 3.14. Taking inspiration from these three digits, March 14 (3/14 in the US date format) is heralded as international Pi Day, first marked by US physicist Larry Shaw in 1988. This year brings a unique opportunity to demonstrate an entirely unnecessary degree of zeal by marking Pi Day correct to nine decimal places on March 14, 2015, at 9.26am 53sec – corresponding to 3.141592653, the first 10 digits of Pi.

If you’re too busy this weekend, you could book in July 22 – another way of expressing Pi approximately is the fraction 22/7. Pi is calculated as the ratio between a circle’s circumference to its diameter. Pi is always the same value, no matter the size of the circle, which makes it an important mathematical constant. The ancient Babylonians calculated Pi as three by taking three times the square of the circle’s radius, later refining the value to 3.125. Click to enlarge Some Properties of Pi. On Pi Day, Celebrate Math’s Enigmas. Photo Manil Suri BALTIMORE — EACH year, March 14 is Pi Day, in honor of the mathematical constant. Saturday is the once-in-a-century event when the year, ’15, brings the full date in line with the first five digits of pi’s decimal expansion — 3.1415.

Typical celebrations revolve around eating pies and composing “pi-kus” (haikus with three syllables in the first line, one in the second and four in the third). But perhaps a better way to commemorate the day is by trying to grasp what pi truly is, and why it remains so significant. Pi is irrational, meaning it cannot be expressed as the ratio of two whole numbers. And yet pi, being the ratio of a circle’s circumference to its diameter, is manifested all around us. Early mathematicians realized pi’s usefulness in calculating areas, which is why they spent so much effort trying to dig its digits out. With the advent of computers, pi offered a proving ground for successively faster models.

So what use have all those digits been put to? FAQ | iZone NYC. A. Language Requirements All Submission materials must be in English. B.

We’re a suite of games and apps that combine play with learning in a way you’ve never seen. We know how to entice kids to play games. We’ve built some of the most popular gaming sites on the web by making fun, free games that competed (we admit it) with homework and textbooks for kids’ attention.

Now we’ve decided to use that expertise, that innate sense of fun, for a greater good. MathGames is driven by a belief: if students applied even a fraction of their free time on math, it would amount to something significant – something that could change their lives. By using the same analytical approach used in other mobile, social and online games we feel we can create engaging educational content that keeps students playing – learning- longer than virtually any other teaching tool. Our games and apps are guided by the Common Core State Standards for Mathematics and pay careful attention to regional curriculum all over the world. Schulaufgaben Mathematik Gymnasium Klasse 6.

Bruchrechnen - Addieren und Subtrahieren, Multiplizieren und Dividieren von Bruchzahlen. Addieren und Subtrahieren von Bruchzahlen Man addiert (oder subtrahiert) zwei nennergleiche Brüche, indem man die Zähler addiert (oder subtrahiert) und den gemeinsamen Nenner beibehält. Beispiele: Beim Addieren (oder Subtrahieren) ungleicher Nenner muss man die Brüche erst durch Erweitern oder Kürzen auf den gleichen Nenner bringen. Danach kann man die Zähler addieren (oder subtrahieren), wobei man den gemeinsamen Nenner beibehält. Multiplizieren und Dividieren von Bruchzahlen Multiplizieren Wenn man einen Bruch mit einer beliebigen Zahl multipliziert, wird einfach der Zähler mit der Zahl malgenommen.

Dividieren Wenn man einen Bruch durch eine beliebige Zahl dividiert, wird einfach der Nenner mit der Zahl multipliziert. Beispiele: Brüche addieren. Weniger Mathe-Stress und Bessere Noten!

Guided by research, educators at Cochrane Collegiate have homed in on ten top teaching methods, and teachers receive weekly PD to help them implement the practices. Watch the video. Teachers keep students on their toes by moving them to different parts of the room during lessons (left). Graphic organizers (right) are another technique used at Cochrane to help students learn new information.

Credit: Zachary Fink The educators at Cochrane Collegiate Academy, in Charlotte, North Carolina, have developed an instructional model called Interactive Learning (IL). It is a collection of their ten best practices, which they call their non-negotiables, and teachers must implement them in every lesson, every day. Shana Oliver, the school's academic facilitator, runs the training sessions for these best practices, and she helps the teachers see and experience how they can incorporate all ten into one lesson.

Free fraction videos online, part 1. Enjoy free online math videos on these fraction topics: (Fraction videos, part 2, are on this page.) The videos are recorded in high-density (HD) and are viewable both here as well as at my Youtube channel. These videos are usable for students, teachers, and parents. You can use them... To learn these topics yourself (if you're a student for example, or an adult needing a refresher)As lesson plans for teaching these topics.

The videos match the lessons in my book Math Mammoth Fractions 1 (Blue Series book), or the lessons in chapter 5 of Grade 5-B (Light Blue series). Mixed numbers to fractions and vice versa I explain both the visual models and the shortcuts for converting mixed numbers to fractions or fractions to mixed numbers. To convert a mixed number to a fraction, divide the whole "pies" into pieces (the same kind of pieces as what the fractional part indicates), then figure out how many pieces you have.
