Teacher Calculator is designed for educators by an educator to save you time grading papers, leaving you more time to focus on your kids (and your life!)

It only does one simple thing, but it does it well.

After specifying the number of questions on your assignment, Teacher Calculator will let you quickly lookup or enter the number of questions a student got right or wrong and show you the student's percentage score.

- Designed specially for teachers to minimize the number of touches -- only enter the total possible once, lookup using the number right or wrong, etc.

- Quickly scroll through a list (works best for assignments with few questions)...

- ...or use the keypad to type in the number (works best for assignments with many questions)

- Easy to use, fast, and works great on iPhone or iPod touch!

Could you do this with any normal calculator? Of course!

However, I know how long grading papers can take, so I designed this calculator carefully just for teachers to save you at least a few seconds per paper.

How many hundreds (or thousands!) of papers will you grade this year? Multiply that times a few seconds saved per paper and this might be the best little investment you've ever made!
