Quadrilateral Properties Flowchart

I put this flowchart together years ago to help our students become familiar and identify quadrilaterals and their properties using side lengths and the slopes of the sides.  The information is usually gathered from a gridded Cartesian graph or sets of ordered pair vertices of the quadrilateral.

Information Needed or to be Derived:

Points:
(x_1, y_1) \text{ and } (x_2, y_2)

Pythagorean Theorem:
\displaystyle c^2 = a^2 + b^2
\displaystyle \text{side length}=\sqrt{(\Delta x)^{2}+(\Delta y)^{2}}
\displaystyle \text{side length} = \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}

Slope:
m=\frac{\Delta y}{\Delta x} = \frac{y_2-y_1}{x_2-x_1}

Ready to save some money on batteries?

1.5 AAA batteryLet’s say:

You have a TV remote or a small book light that uses three AAA batteries.  The TV remote no longer sends signals to the receiver and the book light does not turn on.  What do you do with the batteries?  Do you roll them around?  Do you rearrange the position of the batteries until the device works?  What if neither of those methods work?

Hate Math Love My Glasses by roxagrama

I happened to find this on Deviantart.com. This piece comes from roxagrama on Deviantart.   Although it has an ironic name, I think it shows a nifty perspective through the eyes of a mathematician.  Love it!  I’m curious what the formulas are describing?

Why Do We Need Math?

I know this is probably more of a reblog but I felt it was really important to show math students and teachers. Carl Sagan makes great points about who will be calling the shots in your life and in the real world when it comes to Science and Technology and this clip is less than 3 minutes long.

I’m such a math geek I bring a graphing calculator with me to sleepovers.

Problem Solving in Portal and Portal 2

“The cake is a lie,” but the fun is real!

I <3 Portal and Portal 2!
Portal and Portal 2 are first-person, puzzle games with difficulty levels ranging from easy to clever to challenging.  In Single Player Story Mode, you play the role of Chell who is a test subject kept preserved by Aperture Science Laboratories.  The object of the game is to use your portal gun to navigate your way through each chamber.  Each chamber is designed and overseen for “testing” by the AI central core, GLaDOS.
