There are a number of organizations that are accepting money for Tsunami relief. Many organizations keep a disproportional amount of money for operating costs, which include paying salaries for those who lead the organization. Operation USA boasts 100% of its donations go to the affected regions. In a 2003 Report, Operation USA used 1.2% of its donations for administrative and fundraising costs. Visit Operation USA to donate now.

Our old board (click here to view it) no longer functions. It can and will be used for reference purposes. New posts will no longer be accepted to it.

However, our new board (click here to use it) is working very well. It requires users to first register to use it. The process takes about two minutes to complete, which is a small price to pay to rid us of spammers and flammers.

Enjoy it.

Friday, August 20th, 2004:
MATHguide was experiencing a number of problems related to our bulletin board system. As a result, we had to put into place procedures to deal with the situation.

Tuesday, March 23rd, 2004:
Some changes were made to a few quizmasters because they either were not checking answers properly (area of trapezoids) or were not titled properly (volume of pyramids). The trapezoid quizmaster was not able to recognize correct answers, but it did report the correct answers. The checking mechanism was identified and altered. The title was changed on the volume quizmaster.

However, a new feature was added to the area of plane figures section. Now, readers can take a tour of all five figures with ease. They can take a quizmaster area tour!

Sunday, March 7th, 2004:

Eight new quizmasters have been added!

  1. The surface area theme on solids that we started on April 2nd wouldn't have been complete without a similar one on spheres. Once the quizmasters were complete for surface area, it was extremely simple to modify them to work for volume too.
  2. We added two quizmasters to handle determinants of the 2x2 and 3x3 varieties.
View the lessons page to find our complete list of lessons and quizmasters. Click on the Q's to get to the quizmasters.
