Here's a smile for your Sunday morning.
If you're anywhere near my age you probably remember Ma and Pa Kettle. I used to watch those old black & white movies on weekend mornings. You've just got to click play on this YouTube of Ma and Pa's version of arithmetic.
Another cool song:
The Sound of Friction
This one is the tune of the 60's classic, The Sound of Silence. The link above takes you to an MP3 file of the audio which is clearer than the video. You may want to listen first before sharing with the kids. I loved it but they do throw in the H word.
This is one video you just gotta watch. It's a song about pi put to the music of Don McLean's American Pie:
Math Pi
The kids and I have been viewing Basic Math from The Teaching Company. One thing we learned was how to do lattice multiplication. The video below is a very basic demonstration of the method. I don't think it's any faster than the traditional method of multiplication but the kids have a lot of fun doing it and showing off to visitors. If a new method gets them excited about doing math then I'm all for it!
I'll try to find a YouTube of a more complicated problem than the one shown in this video so you know what to do with larger numbers that need to carry. Hopefully, I'll have it posted in the next day or two. In the meantime, maybe you can figure it out for yourself.
I didn't realize that Mr. Wizard had passed away until I stumbled upon this YouTube.
The kids and I just borrowed some Mr. Wizard videos from the library a few weeks ago. I'll have to do a little searching and see if I can find some of him on YouTube. In the meantime, enjoy this little tribute and balloon experiment:

More cool video from Semiconductor.
Semiconductor 200 Nanowebbers from Semiconductor on Vimeo.
For ‘200 Nanowebbers', Semiconductor have created a molecular web that is generated by Double Adaptor's live soundtrack. Using custom-made scripting, the melodies and rhythms spawn a nano scale environment that shifts and contorts to the audio resonance. Layers of energetic hand drawn animations, play over the simplest of vector shapes that form atomic scale associations. As the landscape flickers into existence by the light of trapped electron particles, substructures begin to take shape and resemble crystalline substances.
