Dance, Factors Dance: Animated Factorization Diagrams #mathchat

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!

What it is:
Google comes out with some really incredible tools and Google Sky is definitely one of them. Think Google Earth for the Sky and you will get a pretty accurate picture of what Google Sky entails. Students can get up close and personal with the Solar System, Constellations, the Hubble Telescope Showcase, Backyard Astronomy, Chandra X-Ray Showcase, GALEX Ultraviolet Showcase, and the Spitzer Infared Showcase. Google Sky also provides students with podcasts about the Earth and Sky. How cool is that? Like Google Earth, students can “zoom in” to a location and pan around. They can also view the sky in different views which include infared, microwave, and historical. Unlike Google Earth, Google Sky can be viewed right from your web browser without a download which makes it very handy for the classroom.

How to integrate Google Sky into the classroom: I think you would be hard pressed to find a school who didn’t have space units woven through curriculum at nearly every grade level. Google Sky is the perfect way to bring that curriculum to life for your students. You can take a virtual field trip to space right from your web browser! The different views and options in Google Sky make it appropriate for kindergarten through college age groups. Your students will enjoy exploring the solar system and learning about galixies with this up close and personal look. This site is perfect for use with an interactive whiteboard or projector for whole class instruction, but would be equally enjoyable on individual student computers where they can explore the universe at their own pace. When students zoom in on an object, they can “hover” over the object with their mouse for some stats. So neat!

Tips: As a side note this would be a great site to couple with the Discovery Series “When We Left Earth.” If you haven’t had a chance to catch the series, they are wonderful!

Hi-
I used Google Sky in my third grade classroom last week, and it was amazing! I just had to do a quick lesson on constellations. I read a little book to intro what constellations are, and then we darkened the room and fired up Google Sky on the front screen, using my laptop and projector. The kids learned so much and loved it! We just were wrapping up the solar system, so we poked around a bit on that portion as well. The students were much more engaged than they were with just the book. At the end, each student received a black piece of paper, and used a white crayon to create their own constellation in the night sky. Thanks for telling me about Google Sky!
