There are two things that are needed most in the classroom:
accurate calculations, and sharp pencils. Why not combine the
two? I suggest a small non-mechanical pencil sharpener built into
a calculator.
I googled this seemingly obvious gimmick, but all that turned up
was one eBay auction for
a dinky little plastic gadget that looked
more like a toy than a tool. What I'm talking about here is a good
old graphing calculator, maybe a TI-83 or 84. These things are a
good two centimeters thick, and have enough room for a small
sharpener built into the bottom.

This thing's a beast. [DrWorm, Sep 23 2009]
Shameless.

a pencil with a little calculator at one end would be cute - need little fingers though. |

Let's have a trumpet with a pencil sharpener as well. Useful when working out solos (or working out solo). |

[+] only if it is powered by the sharpening, somehow. |

I don't see pens as an upgrade to pencils, [21]. They're by far the
cheaper, simpler to manufacture, better for than environment product
that can be erased simply with an eraser. I've not used one since
school, but the pen erasers always just tore up the page in their futile
attempt to scrape the ink away from the page. |

As to putting pencil sharpeners in things, meh. [ ] |

Arguably more fun would be a pencil with a sharpener built into the end (where some pencils have a rubber). This would look useful and handy, right up to the point where you actually wanted to sharpen the pencil and discovered that it was only useful for sharpening *other* pencils. |
|
| |
I know putting pencil sharpeners in things is on uneven
ground for an original idea, but it seems like it would be so
convenient, and doesn't exist, therefore I posted it anyway.
Why not? |

a sharp pencil is essential when the ceiling tiles are fibrous acoustic material and the class is populated with 14 y.o. hooligans. |

//Why don't people use propelling pencils? It's one of those things that you'd have thought would have completely put an end to the ordinary wooden pencil.// |
|
| |
I'm not 100% up on my pencil history, but wasn't the earliest form of pencil, the grip-lead pencil (a form of propelling-pencil lite) - with manufactured wooden cased versions being provided later as a cheaper alternative? |

Oh and [hippo] I love the idea of a pencil with a pencil sharpener at the "other" end - classic. |
|
| |
Or a refrigerator with a pencil sharpener built in, for when you have to note your grocery list. |
|
| |
//a pencil with a pencil sharpener at the "other" end -
classic// I'll second that. |
|
| |
fourth, [hippo] you have an obligation to your public, etc. |
|
| |
Or how about a park bench with a pencil sharpener for those aspiring artists who like to draw trees and such? |
|

Put one on a pint glass... writing and drinking go hand in... well go in both hands, actually. |
