Mathematics
In searching for a meaningful problem to present to my Math Methods class this upcoming Monday, I became extremely frustrated. After an hour and a half on the Internet searching for things like "Math Brain Teasers", "Challenging Math Problems", "Math for High School Students", and the like, I found nothing I could use. I finally stumbled upon the concept of upright numbers. For example, 123 is an upright number because 1+2 = 3. The first two digits must equal the third. Through an hour or so of investigation all the positive 3-digit integers that are upright numbers, I was able to locate some patterns that I was unable to find posted on the Internet. I feel like I actually may have contributed something to mathematics today - what a feeling!

Heather, I love stuff like that! Whenever I'm bored or watching the clock I like to add up or multiply the digits in different combinations and see what I get. Could you post the patterns you came up with somewhere? I'd really like to see them :)
