Math Links for Week Ending Aug. 23, 2013

One of the things that Dan Meyer did this summer is called "Makeover Monday"
where he and his readers take various bits of textbook work and retool them. Here are the results:
Bedroom Area (Area, Rates)
Checkerboard Boarder (Quadratics, Patterning)
Bedroom Carpet (Composite Area, Rates)
Internet Plans (Systems of Equations)
Meatballs (Composite Volume)
Tire Marks (Root Functions)
Postage Rates (Piecewise Graphs)
Ferris Wheel (Periodic Functions)
Shipping Routes (Systems of Equations, Patterning)
Boat Race (Vectors, Geometry)
Penny Circle (Quadratics)

Here is a neat activity that links equilateral triangles and quadratics (or root functions)

One dot, one person. That is, over 300 million dots representing each person in the US. All plotted out and colour coded by race. Neat visualization. Here is the link to the large zoomable map.

I must be fascinated by these things because I know I have pointed them out before. These pictures made of curves are neat. But unrelated to this is a new feature of Wolfram Alpha to "Analyze My Facebook Data". To do this you have to give Wolfram Access to your Facebook page but then it does its magic. Give it a try.

From Edudemic, a nod to McGraw Hill's Eglossary of math

A whole pile of I Have, Who Has cards already premade for math.

Here is a really cool algebra puzzle that requires only generating and solving linear equations. Take a look here

In this video the boys from Top Gear (UK) take a look at how models scale down in size but actually scale up in durability

The Big Bang Theory has no shortage of math references. Here's one that could be used as a Minds On for solving linear equations or speed

I still don't know what the 2nd guy says but this is still kinda funny "street math"
Curriculum Tags: All

I love this one from XKCD dealing with the idea of small probabilities and statements that sound sensational but really aren't
