# A Living Graph

This is one of the neatest little applications that I’ve played around with for a while.  I’m always interested in the best ways to help people visualize mathematics.  This foots the bill nicely.  In the classroom, if you have an interactive whiteboard and want to be able to just easily draw a graph for any purpose, you’ve got to add this to your arsenal.

It’s called the "Living Graph" and it’s very nicely positioned in the category of "thinking tools" by the National Grid for Learning at the Welsh Government website.

One of the challenges when you’re working with graphs is to quickly and accurately draw what you need.  Sure, you can plot a graph with your favourite spreadsheet tool or you can rough it with a drawing tool.  But, the Living Graph offers even more.

Start by setting the parameters for the graph space that you’re working with….

The first Living Graph gives you an x-y grid with the parameters you specify and a horizontal y=0 line.  Simple enough.

Now, it’s just a matter of grabbing a point from the x-axis and moving it into place.  Point by point, just repeat until you get the desired results.

It’s a quick way to demonstrate or show a plot to the class.  It would be even more effective to have students show off their own learning by demonstrating their own solution to problems.

This is a definite keeper for mathematics, science, economics, or anywhere you’re into graphs!

• Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It is used primarily in photography, filmmaking and architecture. It manipulates human visual perception through the use of scaled objects and the correlation between them and the vantage point of the spectator or camera.

• This year Olympics games are scheduled for London, UK from 27th of July to 12th of August 2010. These games will be telecast live on TV. If you don’t have time to watch games on TV then you can always watch it online. There are many websites that will telecast Olympics live.

• What’s the big picture? As educators we need to ask ourselves this question. I’ve spent a week in Ireland with 213 educators from around the world. I’ve already been asked to share my key learnings. Honestly I’m not sure how to begin to share what I’ve taken in this week. Friendships, tech tips, the evolution of tech, new instructional ideas, new apps, new projects and of course, lots of photography guidance. But, what is the big idea I’m really taking away from this institute?

• We recently reported on a man who claimed that Microsoft had locked him out from his own Microsoft Account after finding disallowed content in a private folder on his SkyDrive. That raised some questions about just how private private SkyDrive folders are, and after a bit of investigation, we’ve got a response from Microsoft on the issue.

• It must surely be a sign of the impending apocalypse that Microsoft’s operating systems have “more taste” than Apple’s.

I’m referring, of course, to Apple’s inexplicable use of skeuomorphic design in iOS and OS X apps, and contrasting that with Microsoft’s stark avoidance of such cheesy gimmickry in the Windows 8 and Windows Phone user interfaces.

• Is free online learning going to put traditional colleges out of business? For a college professor, it’s hard to read the news these days and not worry about this threat. For one thing, the businesses of journalism, publishing and music, all decimated by the internet, bear uncomfortable similarity to that of higher education. In each case, valuable intellectual property is threatened by free online copying and distribution.
