Math Links for Week Ending Apr 26th, 2013

Get the Math has been around for a couple of years but when it first came out it only had a few activities. Not sure how I cam across it again but I see that it has expanded its content. The premiss is that it would highlight a real context that math was used and then build an interactive activity around it. So far they have fashion, music, video games, basketball, restaurants and special effects. With topics like ratio and rate, percents, plotting points, linear relations, quadratics and exponential relationships. Personally my favourite is the music activity with ratios and sampled beats. Very cool. Below is the intro video for that activity

I have mixed feelings about the whole effort to make tutorial videos about doing math. Not so much about whether they are a good idea but more about the quality of what is out there. There are certainly large repositories (the Khan Academy) but its navigating those videos can be a problem. Phoenix College has tried to address that with this simple interface. Start with a topic and then that is further broken down into sub topics until you find the video you want. Thanks to Free Technology for Teachers for turning me on to this one.

Download this free poster of colour coded trig identities from the Math Four site. A nice visual aid that you could print out for your grade 11 students.

I like this simple experiment. Next time it snows (hopefully not soon), fill up a glas with it and estimate the amount of water when it melts. You could create all sorts of data when doing this and then use that to connect snow fall with regular precipitation.

Apparently the portion of the brain that is in charge of doing math is
localized to one area. At least that is what it seems a new research paper is saying. Read more here. Thanks to Mark Esping for this one.
