Free tools every math blogger should learn

High School Mathematics, Teaching Tools, Web 2.0 Technology

Although the list below is specialized for math bloggers, they can be used by bloggers of any field. I have used all the software below,

  • WordPress. WordPress is a free blogging site. Upgrade is available (for a fee) for larger storage and domain name customization.  I chose WordPress to host Mathematics and Multimedia mainly because of its Latex support. As of this writing, as far as I know, two of its top competitors, Blogspot and Typepad, do not support Latex yet.

  • Blogger/Blogspot. Blogger is also a blogging website that is included in Google Applications.  Once you have a Google Account, you already have a blogspot account, you just need to activate it. I use Blogger to embed GeoGebra applets since JavaScript embedding is not allowed in WordPress.com.
  • Google Docs. Google Docs can be used to store and share documents online. It has its own word processor, spreadsheet, and presentation software. It has currently released a new drawing software.  You can use Google Docs to store your documents and link your blog to it.

Yes, you guessed it right, 6/42 means 6 numbers are randomly chosen from a set of numbers from 1 through 42. We use the 6/42 lottery in the following discussion. » Read more

Math Teachers at Play 30 (via JD2718)

High School Mathematics

Math Teachers at Play is now posted.

Welcome to the September 17, 2010 edition of math teachers at play. This is MTaP #30. This MTaP may look a little different. There is no theme weaving its way through and unifying the sections. We are not opening with a discussion of the number 30 (no matter how many cool things we could have come up with), and the sections are, um, different. It has occurred to some of us that the experience a student has in mathematics may differ greatly from p … Read More
