HDubz Day 2

Hi all,

Here is your hdubz from the second day of classes. Please watch the video below, which will give you some information about how to access Khan Academy.

Please bring a computer, iPad, or iPhone to class tomorrow as we will be signing up together and talking about how to access

Welcome to math class!

Hey guys, welcome to the blog, here is a video of how I spent my summer - rapping about some of the service projects and trips I led:

For hdubz I have found a few articles on the current state of math education in the world. Some of them are very college based or United States based, but I think they get their point across. Please choose one to read and comment on this blog posting with a minimum of a 50 word response. You will not be graded on your opinion, but you will be graded on how closely you read the article and how well formulated your opinion is. Please let me know which article you've chosen and include your name, there is a sample below.

Is Algebra Necessary? New York Times:
