EDIT: I am currently writing an editorial to convince the school to start using Casio Prizms.

Good move (hoping it convinces them)

I may have mentioned something like this previously somewhere but here is the chronology of my school calculator history

2008 (opening year): TI-84s (at least I think so)
2009: TI-84s (maybe SE, I remember a green white colour version)
2010: (my year): TI-nspire Clickpad (some decided to stick with TI-84s though, these are light blue (?))
2011: TI-nspire Touchpad
2012: TI-nspire CX

We had to buy all these either from Officeworks, or from a third party Australian supplier.
Now I'm graduating in Year 12, in under two months. Some in my year have just bought CXes because they couldn't bother to upgrade the OS, (or they wanted the colour screen), others have asked me how to upgrade (since I'm the only person in the school that has much knowledge of this stuff)

I guess my school wins the prize for wasting the most money, because those Nspires had to have cost anywhere between 80000 to 150000 dollars.
The couple hundred ti 30X must have cost a couple thousand dollars.
Also, several science classrooms get a set of 30 TI 83 +’s or TI 83 silver editions.
So that’s another 30000-50000 dollars possibly.
So 110000-200000 dollars spent on calculators, when physics and statistics are the only classes we need them for.

Your school buys them for you? Including (especially) the graphical ones?
Wow now those are some very big (possibly exaggerated) numbers

EDIT: My old school mainly used Casios. That's how I first got introduced to graphical calculators.

800*$120 = $96000 for the nspires.
but still a lot of money o.O

probably around that. and lets say 800 ti-83(+)'s cost 800*$110=$88000

Ah, I thought they got it for keepings

my class uses ti-86
my sister's class use cx.

Our school has a ton of TI-83 Plus calculators to check out from the school library.
