Teachers Love SMART Boards: Mathematics I was searching through my past blog posts and I'm quite surprised that I have not written a post about the amazing flash-based resources found on Crickweb. This site contains hundreds of quality interactive resources for children aged 4 to 11. For my U.S. readers, the activities are organized into three age groups: The Early Years (age 4 to 5), Key Stage 1 (age 6 to 7), and Key Stage 2 (age 8 to 11). The basic subject areas include Math, Science, History, and Literacy. Spanish, and even Design & Technology. The resources contained on this site are all interactive and very few of them require keyboard input. of the activities only require students to touch or drag objects. I've included a few screen shots but the best way to find what your looking for is to browse around and play with the activities. Sharing is Caring!
3D Functions Plotter - Graficas de funciones de dos variables y calculador de integral doble Functions 3D Plotter es una herramienta on line que permite hacer gráficas de funciones reales con dos variables, es decir, funciones del tipo f: R2 → R (x,y) → f(x,y) 3D Functions Plotter calcula la integral doble en formatos analítico y numérico.

Game Theory, Behavioral Finance, and Investing: Part 1 of 5 | Portfolio Investing Blog: Portfolioist Watching the market this year has been like observing an exercise in game theory and behavioral finance, and the two fields are closely related. Game theory is the study of how a rational person makes decisions in uncertain situations. As the name suggests, game theory was developed with the intent of developing optimal strategies in games in which chance or the decisions of an opponent play a role in your outcome. There is a huge literature of both game theory applied to financial decisions and behavioral finance. Notice that in my description of game theory, I write that people act to maximize their satisfaction rather than their returns or their wealth. The games on Wall Street come in a variety of forms. In this five-part series of posts, I will explore a number of the challenges that investors face from the perspective of game theory and behavioral finance.

Numbers= & programs for smartboards Number, Problem Solving A mathematical based puzzle for IWB, iPad and Android that requires some careful numeracy thinking and some informed trial and error. When the resource opens you will see that both multiplication calculations give the same result of 3634. The highest number that can be the answer for both calculations using each of the nine digits once is 5568. The challenge is to arrange the numbers until both calculations equal 5568. Tap one tile and then another to swap them. The resource requires a modern browser and will work on all platforms. Go to math puzzle. Investigations, Number, Problem Solving This resource was inspired by the Puzzle of the Month in the always informative newsletter by Andrew Jeffrey, also on twitter as @AJMagicMessage. The puzzle is easily played using counters or sticky notes but to alleviate the danger of rogue gust of wind or sneezes this resource lets it be played or demonstrated on computer or tablet, either iPad or Android.

BRAND NEW 2008 Line of Fractal Imagery -- 594 Images -- Oh Wow! ---> Show me the fractals! Guess Your Birthday! Here's a fun trick to show a friend, a group, or an entire class of people. Step 1) Have them take the month number from their birthday: January = 1, Feb = 2 etc. Have them give you the total. How It Works: Let M be the month number and D will be the day number. Thus, if you subtract off the 165, what will remain will be the month in hundreds plus the day! By the way, if you wish to know how many minutes and seconds you have been alive and lots more about when you were born, you might like to try this website ==> Birthday Calculator Divisibility Rules!

The Costs of “Good” Economics If there is a central argument to 13 Bankers, it is that politics matters. The financial crisis was the result of a long-term transformation of the financial sector and its place in the overall economy, and that transformation occurred because of—and contributed to—a shift in the political balance of power. Daron Acemoglu and James Robinson, authors of Why Nations Fail, take up this theme on a much broader scale in their recent article in the Journal of Economic Perspectives, “Economics Versus Politics: Pitfalls of Policy Advice,” burnishing their reputations as two of the most subversive thinkers around. People have always known that economics and politics are related: that economic power produces political power and that political institutions constrain economic policy choices. This is what Acemoglu and Robinson contest. One specific consequence of weaker unions is that “income will typically be redistributed from workers to the managers and owners of firms.” This all seems obvious.
