Congratulations -

To Mrs. Murphy's 2009-2010 Integrated Algebra Class
With all the multiple choice questions done, you have achieved a 100% pass rate. Good Work boys.

Although I must say two of you did make me hold my breath and should be thanking the math gods as you read this. (SKIN TEETH YOU!)

Have a great summer boys! See you next year. It has been a real honor and pleasure being your teacher this year.

Read an article from Math Plus Magazine OnLine Browse through the magazine and chose an article. Post the name and author of your article here. If someone has already chosen your article then you must make another choice. (No two students can report on the same article). For now I just want the article name and author. You will read your articles next week and prepare an oral presentation for the class (complete with mathematical explanations). Rubrics for this project will be posted on Monday, April 26th.

Solving systems of equations

Visit SOLVING A SYSTEM OF EQUATIONS BY GRAPHING and complete the tutorial. Write a reflection of the tutorial here. Hand in the completed exercises from the tutorial tomorrow in class. For more help with graphing quadratic functions by hand visit PurpleMath.com
For help with graphing quadratic functions on your graphing calculator visit MathBits.com


For your reflection consider:

Was the tutorial easy to follow?
Did the tutorial help you?
Were the examples good representations of real world problems?

Try to find a real world situation that would involve applying a system of equations to solve. Share it with your classmates here.

Why does a negative * a negative = a positive

This week I was on the phone with my mom discussing the difference between teaching math conceptually verses procedurally. She argued that some math procedures have no conceptual base.

My arguement was that the nice thing about math is that everything you do is based on a counting concept. So, she brougt up multiplying negatives, arguing that this rule has no conceptual base.


I disagreed....give an example of what my proof was by posting the reason why
-2 * -2 = 4. Show the math if you can
