Eh… What’s up, Math Teacher?


What’s up?  This is what’s up…. this link will take you to a TI-73/83/84 FREE emulator called WabbitStudio Z80 Software tools!

It is not as good as TI SmartView, but if you are on a budget, this will do. Here are the directions to create your ROM image for your emulator after downloading the program. Try it out and may you have a great school year!

Yet Another Frickin’ Graphing Calculator Update

Leave a comment

Can you actually believe that they are updating the TI-Nspire already? I don’t think that its worth going to Baltimore for NCTM to see it.

Well, maybe so… Looks like they just seperated the numeric and alpha keypad. Unfortunately the keypad is not in the QWERTY format. I wonder if the upgrade is only the keypad upgrade, not the whole kit and kaboodle. Also, I wonder when they will update the TI-84 OS on the TI-Nspire that will allow the cool features of version 2.53MP?!

TI… we need some answers!

Graphing Calculator Upgrade Pains

Leave a comment

Last week, I was happy to discover of the new OS upgrade for the TI-84 graphing calculator. Unfortunately my school has a limited supply of the 84’s and a plethora of the 83’s.

So until TI mirrors the upgrade or makes MathPrint available on the 83, there will not be any function equitability. My issue is that high stakes testing is around the corner and I am hesistant in recommending in upgrading the 84 devices due to this issue.

I played around with the new upgrade this weekend and it is a great addition to the 84. (As a highschooler, I would be thrilled to perform matrix functions at the home screen.) In NC, 8th graders are permitted to use graphing calcs for the whole test (End-Of-Grade).  The MathPrint function that allows stacked fractions would really give them an edge.

So, TI…. what is next?

TI-83 Goes Color!


Well… not quite yet officially from Texas Instruments.

However, through modification, you can refurbish your $89 paperweight (BROKEN TI-83/84). This hack can be done by following the instructions on Mark Bowers’ blog. I may try it out if I can pick up a GameBoy Color unit at the local Good Will at a decent price.
