EduTecher’s Change the World

What it is: EduTecher’s Change the World is a campaign started by @adambellow at EduTecher to transform the world one penny at a time.  Between October 1 and November 25 every new user that enters EduTecher.net will allow @adambellow to donate 1 penny on their behalf to a charity that his audience votes on.  The charity that gets the most votes will get a check.  The idea is that we can change the world together, one person at a time.  Want to make an even bigger impact?  If you have a blog, website, or Facebook page you can post the Change the World badge or link and every time one of your readers or friends clicks on it another penny will be donated. I am taking @adambellow’s idea the step further and will offer the same.  For each new user that comes to iLearn Technology between October 1 and November 25 (2010), I will donate a penny to a charity that we will vote on here.   So, if you would like to double your difference, you can add the EduTecher’s Change the World logo and link along with the iLearn Technology Change the World logo and link.  This is a great idea of a little way that we can start making a difference in a bigger way. You can view the video explanation below: How to integrate EduTecher’s Change the World into your curriculum: Why not create a similar school wide campaign to change the world one penny at a time?  You can collect pennies as a class or if you have a class blog or student blogs, issue a similar Change the World Challenge.  As an added bonus, map out where your “pennies” are coming from and have your students write an introductory letter to the charity and include a map of where the money came from!  If you aren’t familiar with the EduTecher website, it is definitely worth checking out.  EdTecher reviews web 2.0 tools for the classroom, they have a great collection of web 2.0 for students and teachers all in one place. Tips: Add the EduTecher’s Change the World badge to your website, blog or Facebook page and then double the change by adding the iLearn Technology badge.  Together we can (and will) change the world.  If you are extending the change please let me know in the comments below, I would love to see how far reaching this is! iLearn Technology badge: Code to place badge on your site: <a href=”http://ilearntechnology.com”><img title=”Change the World” src=”http://ilearntechnology.com/wordpress/wp-content/uploads/2010/09/iLT-Change-the-world.png” alt=”” width=”235″ height=”151″ /></a> Please leave a comment and share how you are using EduTecher’s Change the World in your classroom!

What it is:  Dance, Factors Dance is a fantastic site to visualize factorization diagrams.  The first “tango” is inspired by the digital clock, with a separate diagram for each of the hours, minutes and seconds.  The Factor Conga is a “promenade of primes, composites, and their constituents, arranged with an aesthetically-tuned variation of Yorgey’s rules, one per second.”  I love the way these math factorization dances help students visualize numbers and Prime numbers.  Brilliant!

How to integrate Dance, Factors Dance into the classroom: Dance, Factor Dance is a stupendous way for students to visualize and think about numbers.  I Love the way that the prime numbers are depicted…so easy to see why it is a prime number!  Ask your students to explore this site and identify the patterns they notice in the dance of numbers.  What happens when a number is prime?  When a number is odd?  Even?

Dance, Factors Dance is a fun way to learn more about numbers, it is also a wonderful inspiration for finding the art in math.  How can students use the site as inspiration to create their own math dance?  Could they use stop motion animation and manipulatives to do something similar?  What patterns in math do they notice?  How can they use color and design to help them better understand math?

This site is a great one to explore as a class, as a center on classroom computers, or individually on student devices.  Students can pause the dance, rewind, and fast forward as they explore.

Tips: Be sure to watch (or fast forward) to the three digit numbers…this is where things get really impressive!  As a side note, I learned something today from a fellow teacher.  When looking at numbers in grid form, you know if a number is prime if it can only make one rectangle.  This understanding would have been helpful in math class! Better late than never :)

We have already taught this concept, but this is a perfect way to reinforce it! Thanks!
