Mathmagic-Happy Birthday Harry Houdini!!


Today is the birthday of Harry Houdini (1874-1926).  He was a famous escape artist who used his mathematical prowess, as well as his skill and bravery in many of his tricks.

Let's celebrate with a little math magic!

In a lively show, mathemagician Arthur Benjamin races a team of calculators to figure out 3-digit squares, solves another massive mental equation and guesses a few birthdays. How does he do it? Unlike Houdini, he’ll tell you.  http://www.ted.com/talks/arthur_benjamin_does_mathemagic.html

Building Connections is to Build Understanding!

We could not have said it better ourselves...please check out the post on Math4teaching.com (link below)


"To understand is to make connection. The stronger the connection the most powerful the understanding. One of the ways to help students to make connections among concepts is to give them problem solving tasks that have many correct solutions or answers. Another way is to make sure that the solutions to the problems involve many previously learned concepts. This is what makes a piece of knowledge powerful. Most important of all, the tasks must give the groundwork for future and more complex concepts and problems the students will be learning. These kinds of task need not be difficult."
