How I use my iPhone and iPad as a college math teacher

As a college math instructor, I am a huge advocate for technology use in the classroom and regularly use my iPhone and iPad to enhance the learning experience for my students. Between using apps on the classroom projector, enabling Guided Access for student devices during exams, and preparing content at home, my iPhone and iPad are essential tools for me as a teacher.

Add calculator functionality to iOS search with QuickMath [jailbreak]

QuickMath is a new tweak that allows you to do simple math functions within iOS search. If you're a Mac user you're probably already use to this kind of functionality within Spotlight. I've definitely caught myself a time or two swiping to search on my iPhone to do a simple math problem and quickly realizing that I can't.

Once you install QuickMath there is nothing to configure. Just swipe on over to search and type in your math problem. Hit search and the solution will show up in the search bar. It's a bit quicker than searching or paging through for the Calculator app in my experience. Maybe this math tweak will be enough to make Leanna jump over to #TeamJailbreak?

QuickMath is available in Cydia for free.

Create geometric trees with Geom-e-Tree for iPhone and iPad

Geom-e-Tree is a great geometry app that creates fractals-like trees and has been updated with new themes.

Create an infinite number of fractal-like trees with a few simple gestures. Surprise yourself and friends with the variety and complexity of the patterns you discover just by changing the number, angle, and the common ratio of your tree's branches. It's math and it's art - and it's totally captivating.

  • Touch the screen to make your tree grow and change.
  • Watch your tree morph in real time.
  • Increase the number of branches for fuller trees.
  • Lengthen or shorten the branches to make the canopy change shape.
  • Spread the branches up to 359 degrees for kaleidoscopic patterns.
  • Choose from 20 serious, zany, colorful themes.
  • Explore the many levels of this geometric landscape on your iPod, iPhone, or iPad!

We've added rainbow and "psychedelic" themes, some wild black and white themes (Magpie and Op Art), as well as a few monochromatic themes (India Ink and Pop Sticks). The new Themes tab displays all the themes and allows you to choose one for the current Tree. The Arboreturm remembers the themes of newly added trees. Geom-e-Tree also includes all the themes from our new version of Geom-e-Twee!

In mathematics, a fractal is is geometric shape that is split into parts, each of which is a smaller copy of the whole. This app is great twist on that idea and it's fun to watch your trees grow. They even snuck in some famous fractals! Even my 11 month old daughter enjoys this app - she stared at it in awe of the colorful trees growing.

Geom-e-Tree is available on the iPhone and iPad for $2.99. The junior app, Geom-e-Twee is available on the iPhone and iPad for free for a short time.

iPhone is AT&T's Top Earner

Highlights from a report from a report by Strategy Analytics:

  • iPhone tops AT&T sales chart at 13% of AT&T's device sales
  • 4th best-selling phone in U.S., selling 1.1 million units. Total # of iPhones sold: maybe 1.325 million
  • based on current trajectory, iPhone will be #1 best-selling phone in the next quarter or two
  • current #1 is still the RAZR V3
  • two age segments standing out that are purchasing iPhone in droves: 20-30 and 50-60.
Having owned a RAZR and been frustrated with the poor software shipped on it, I will do a little dance when it's no longer #1.
