Math Links for Week Ending Feb. 12th, 2016

Some great action via Twitter for those who teach calculus. First I helped out a bit on a Desmos Activity created by @mjfenton on rates of change with non linear functions as well as looking at non linear regression can function concavity and modelling with real data. Give it a try

The second one is about derivatives of exponential functions from @Thalesdeciple. It starts out like a Match My Graph activity and then quickly moves into the comparison of the graph to it's derivative. I think that when we are dealing with teaching calculus, having these sorts of dynamic activities are just the thing to help students visualize the ideas that Calculus brings. And because calculus, in my opinion, is the pinnacle of high school math, having more of this sort of thing is great. So keep it up, Internet. Thanks to @marybourassa for pointing this one out

A classic problem turned into a 3Act task from @mathletepearce. No matter how often you give students this problem, it is always a great way to exemplify the nature of exponential growth. It's also good to deal with geometric series due to the discrete nature of the problem.

Though @AlexOverwijk first posted this activity 3 years ago, I'm glad @wheeler_laura pointed it out with some Desmos activity builder additions and a Pear Deck slideshow (plus I like the Google Doc version of the squares). We have a similar activity on our blog but we don't have 26 squares and certainly don't extend it to anything beyond the Pythagorean relationship like they do here.

I'm always looking for Geometer's Sketchpad resources. Last week this site was pointed out to me by Chris Kunkel. It is sort of a one stop shopping place for some of the best GSP resources. Links to the Dynamic Number site as well as links to many of the Web Sketchpad sketches. There is stuff on transformations of geometric shapes all the way up to trig functions. Take a look

I am not sure how long this has existed but if you are new to Desmos, then the site will probably help. I like the fact that it has different levels of learning depending on what grade level your students are. These are not just videos but interactive activities that walk through some of the many features.

Many of you are Smartboard users and possibly CLIPS users. Well apparently Smart is dropping Flash support in the latest version of their software. This video from @4GBrotto gives us the 411 on ways to work around this issue. Thanks to @rossisen for pointing this out.

Awesome animated gif to show the connection between radians and degrees.

Yep, another "only a genius" Facebook post

I love how these all seem to include some reference to Einstein. The order of operations ones are my least favourite

The Superbowl was last week but here are some data posts that relate. The first is from @stupidcalc

And of course you can't have a Superbowl without one about consumption. Thanks to @mark_esping for pointing this one out.
