Math Links for Week Ending Dec. 27th, 2013

I really like Arthur Benjamin. Not just because he was a featured speaker at OAME 2011 (of which I was the Co Chair), but also because he is pretty good at mental computation and also thinks that knowing probability & statistics is more important than knowing calculus. And now he has done his third TED talk, this time on Fibonacci. And I know there are all kinds of videos on Fibonacci out there but I really like the way he connects the geometric to the numeric. A good video for anyone teaching about sequences or patterns.

You can never have too much data or too many good representations of data. Here you can find a collection of some of the best graphs dealing with behavioural science. And although its not new, probably my favourite is the one on water consumption in Edmonton during the 2010 Olympic gold medal game. This is certainly good for any classes looking at interpreting graphs.

Need some data on linear relations? Want to use technology in your classrooms? Have a video camera of some sort? Been to an airport? If you have answered yes to any of these questions then take a look at this link where someone was bored at the airport and collected some simple linear data. This data exists all over (not just airports) and this post shows how you can use the Tracker software to analyze any motion.

In grade 9 we have to connect the algebraic form of Pythagorean Theorem to the geometric. This video tries to do just that. Thanks to Corrie Silva for this one

A relatively new video from Vi Hart on logarithms. I totally love the way she starts with simple addition and works her way to logarithms. At first you don't see the connection but I think the payoff at the end is worth it.

And finally something to put you in the holiday spirit. I wish I was smart enough to know if it is correct though.

Math LInks for Week Ending Aug. 30, 2013

Data from Twitter has given empirical data to measure the subtle differences between a nerd and a
geek. 2.6 million tweets from Dec 2012 were analyzed to find terms associated with geek and nerd and a cool graph was born.

Everyone that teaches quadratics will eventually use a "frame" problem. Here is a nice rework of an already good activity dealing with this type of problem from the I Speak Math blog

Geez that Dan Meyer knows how to maximize his Klout score. This is a really great use of twitter. Here is his tweet:

Then what follows is a barrage of tweets with great real examples of something that is conceptually hard to find examples for. Well done Dan (and Twitter). See the discussion here:

Might as well stick with Dan Meyer some more with this really nice real world metric/imperial conversion task. Nice rework of this basic textbook question. Once again, Twitter to the rescue. It is interesting how minor tweaks can spice a question up to be more problem solving.

The massive numbers that surround UPS (and any courier service). How about this for a Big number. $30 Million: how much extra it
would cost if every driver went just one extra mile per day. This could be used to talk about the ide of big numbers or about combinatorics.

Why not end on some humor. Some real bad math here in a bunch of visual examples. For example, see if you can spot the error in the quadratic formula (its actually hard to see but its there):
