What is a biconditional statement?

Define a biconditional statement and provide an example of a biconditional statement.  Also, use symbolic notation to represent your hypothesis and conclusion.

Parents, I need your input!

Dear parents, I encourage you to provide input about this blog.  Please post your reflective comments so that I can learn from them.  The whole purpose of this blog is to provide a modern method of interaction with students, and of course, to provide a fun, and productive learning experience.  Your posts will also be counted as extra credit for your son/daughter.

What is a question?

Any good question will do when posting a question.  For example,

What is the difference between the converse and the contrapositive of a conditional statement?

What is a good summary?

By now, you should know what a good, well-written summary is - you have been writing summaries since the beginning of the year.  However, I will provide an example below.

In today's lesson, we covered conditional statements and the converse of a conditional statement.  A conditional statement is a statement written in the "if-then" form which contains two parts, a hypothesis and a conclusion.  The "if" part is the hypothesis and the "then" part is the conclusion. The converse of a conditional statement is simply formed by switching the hypothesis and conclusion. 

For example,

Conditional Statement:  If you post a summary on this blog, then you will receive five extra points.
Converse:  If you receive five extra points, then you will post a summary on this blog.

Welcome Students

Welcome Geometry and Algebra students to my interactive classroom.  Now you can post your questions or cornell-notes summaries to receive extra credit points.  You will receive five points for each well written post.  Your summaries must be specific and must contain at least one example of the material covered during that class.  If you choose to post a question, it must be relevant to your specific subject. The extra credit will be applied towards your homework, notebook, or quiz grade category. I hope you take advantage of this so that you can improve your grade.  And now, let's blog...
