I’ve been wanting to post this problem for a long time. I don’t know why I’m so lazy.
Suppose you have a 5 x 5 peg lattice board like one on the right:
Without injuring yourself or others, how many rubber band squares can you make on the board?
How many rubber band squares can you make on an N x N peg lattice board?

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?
Ever wonder if there’s any creativity in logic and math? Do left-brained people struggle to be creative? Where does creativity and logic come from?
I was curious what it would look like if rotated rotating points around center points around another center point. LOL. Try saying that 5 times fast!
Using GeoGebra, I made this worksheet for us to see.
Try making some designs and take pictures of them!
Creativity and Logic come from Curiosity.

In my last post, Problem Solving in Portal and Portal 2, I made a quick introduction to the games Portal and Portal 2. In Portal 2, you have the option of making Testing Chambers in the Community Workshop for others to play and solve.
“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.
Suppose you have a circle and you have to cut the circle into 4 regions of equal area with only 3 cuts. Where do you place the lines? Is there an exact strategy or is it a manner of approximation. Either way, it’s not as easy as one might think and yet the game is tantalizingly fun.
