Math Links for Week Ending May 10th, 2013

Right out of the gate, a great post from Dan Meyer. He has been showering us with 3Act Tasks for years now but now some more detailed info on how to actually execute them in class. Read the entire blog post here (including all the great comments, particularly Kate's about what might happen when you try to do one of these):

I really liked this "real world" task dealing with speeding tickets given by the police but measured by pilots in the air using hash marks on the roads. I remember as a kid, my dad getting one of these on the 401.

The first of two posts from the Square Root of Negative One on Trig. Both are activities. This first one is a hand related way to remember trig ratios of special angles. One thing I like about this post (besides the insights) are the links to others that have posted about this so that you can get many perspectives.

The second is a series of flash card activities that deal with trig ratios and various angles. I like this because with a single set of cards, she has come up with sev
eral ideas of how to implement them in the class (even giving insight as to what might go wrong).

Hey? You want some math comics, how about this site that is chock full of them: Weapons of Math Destruction. If there was social commentary of math and education of math, this might be it.

I really liked this article from a math teacher about what its like to have math anxiety. I think that a problem that many of has as math teachers is that most of us probably did well in math and thus have no empathy for someone who struggles. And by not having that perspective we might actually dismiss any issues that kids have as trivial. But read this article and particularly, I like the bullets at the end of the typical kid who can't do math.

We will round out this week with a neat animation created using oscillating sine waves. Nice application of trig functions
