Algorithm Flow chart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≥ A yields "yes" (or true) (more accurately the numberb in location B is greater than or equal to the numbera in location A) THEN, the algorithm specifies B ← B − A (meaning the number b − a replaces the old b). Similarly, IF A > B, THEN A ← A − B. In mathematics and computer science, an algorithm ( i/ˈælɡərɪðəm/ AL-gə-ri-dhəm) is a step-by-step procedure for calculations. Informal definition[edit] While there is no generally accepted formal definition of "algorithm," an informal definition could be "a set of rules that precisely defines a sequence of operations Boolos & Jeffrey (1974, 1999) offer an informal meaning of the word in the following quotation: The term "enumerably infinite" means "countable using integers perhaps extending to infinity."

The Man of Numbers: How Fibonacci Changed the World by Maria Popova What Medieval mathematics have to do with remix culture, publishing entrepreneurship, and gamification. Imagine a day without numbers — how would you know when to wake up, how to call your mother, how the stock market is doing, or even how old you are? We live our lives by numbers. Keith Devlin tells his incredible and important story in The Man of Numbers: Fibonacci’s Arithmetic Revolution, tracing how Fibonacci revolutionized everything from education to economics by making arithmetic available to the masses. The change in society brought about by the teaching of modern arithmetic was so pervasive and all-powerful that within a few generations people simply took it for granted. The Latin phrase 'filius bonacci,' in the first line of the Liber Abbaci manuscript, gave rise to Leonardo da Pisa's modern nickname, Fibonacci Image courtesy of The Library of Florence via NPR A page from the Liber abbaci manuscript.

Mangahigh.com Adaptive Curriculum The History Of Zero From placeholder to the driver of calculus, zero has crossed the greatest minds and most diverse borders since it was born many centuries ago. Today, zero is perhaps the most pervasive global symbol known. In the story of zero, something can be made out of nothing. Zero, zip, zilch - how often has a question been answered by one of these words? Countless, no doubt. Yet behind this seemingly simple answer conveying nothing lays the story of an idea that took many centuries to develop, many countries to cross, and many minds to comprehend. When anyone thinks of one hundred, two hundred, or seven thousand the image in his or her mind is of a digit followed by a few zeros. The Sumerians were the first to develop a counting system to keep an account of their stock of goods - cattle, horses, and donkeys, for example. Brahmagupta, around 650 AD, was the first to formalize arithmetic operations using zero. But it would still be a few centuries before zero reached Europe. References: 1. 2.

The Michigan eLibrary AEA 267 - Thinking Skills & Reasoning Introduction This page is designed for busy practitioners trying to design performance assessment tasks that align standards and benchmarks with assessments that really measure what's valued and that incorporate higher order thinking skills. Thinking skills and reasoning processes are considered a critical element to designing purposeful performance assessment tasks, as well as thought-provoking pencil-paper test items by experts such as Jay McTighe, Grant Wiggins, Richard Stiggins, Art Costa and Robert Marzano, to mention but a few. For decades, teachers have been learning about the levels of thinking skills/processes (i.e. Bloom's Taxonomy) and attempting to provide work for their students in such a way that it provides the practice, rehearsal and scrimmage necessary for students to become competent thinkers. What you find provided at this site, are templates reflecting a combination of the work of many great educational leaders, local as well as national. Material Use
