Just Doodling: Making Math Relevant for Students

What it is: This has got to be one of my new favorite videos on YouTube.  I ran across this video and tweeted about it a few weeks ago, but felt that it deserved a blog post.  Doodling Stars (above) is a stream of conscious video about doodling in math class instead of  learning about factoring.  As the video unfolds, you quickly realize that she has learned all about factoring through her doodles.  I would have connected in some major ways to this video when I was in school (maybe that is why I like it so much now), it would have given me that “wait that was math?” moment.  Doodling Stars is a video by Vi Hart who has a blog where she has other great math videos.  Her other videos include: Binary Trees, Snakes + Graphs, Infinity Elephants, and sick number games. Explore the blog a little further and you learn that ViHart is serious about her math.  In addition to videos she has mathematical foods, ways to play with balloons as mathematical models, paper instruments (relating music to math), music boxes, bead work, and a variety of other math/music resources.  Vi describes herself as a mathemusician, dig into her blog and you will know why!

How to integrate Doodling Videos into the classroom: Math shouldn’t be a subject confined to a textbook, seen only in terms of equations and functions.  I think I was in college before I figured out that math was all around me.  I had truly never made the connection to the formulas I was learning and their applications in real life.  Oh sure, there were the “If you left Denver at 1:05 pm driving an average speed of 63.2 miles per hour and arrived at another point 12 hours later how many miles have you traveled?” But really? That is not real world…I have NEVER calculated any sort of trip that way, and anyway, now there is an app that will give me all of that information if I really want to know.  If someone had told me that math was in my doodles, in the music I listened to, in patterns of nature?  Now that is something I want to explore more.  I’m sure you have students who have never made the connections between the formulas they are learning and the applications that are all around them.  These videos will have them visualizing math in a whole new way.  Dig a little deeper into Vi’s blog and share her math foods, balloons, and paper instruments.  See if your students don’t start viewing math differently!  Use Vi’s blog as inspiration for your next math lesson.  Use the videos to help introduce or reinforce concepts, or have students complete balloon math models.

Tips: If you can’t access YouTube at school, use a tool like Kick YouTube or Keepvid to download the video for offline viewing.

Google Sky

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!
