Upgrade TI-Nspire to TI-Nspire CAS

(https://www.techpoweredmath.com/review-ti-89-vs-ti-nspire-cas/) I’m kind of obsessive about checking my analytics report to see what people are searching for. Lately, I’ve noticed the search coming from time to time “how to upgrade ti-nspire to ti-nspire cas.” This one makes me chuckle a bit (sorry if you arrived here on that search phrase and I’m chuckling at your expense). I would never put anything past the resourceful hackers/programmers at sites like ticalc.org an Ominmaga.

TI-36X Pro Arrives

UPDATE: I have completed my TI-36X Pro review. Still no word on the arrival that everyone is waiting for, the TI-Nspire CX. In the meantime, however, Texas Instruments has provided me with another 2011 Spring arrival to take a look at, the TI-36X Pro. As far as I know, you can’t find this in stores yet. Since it’s not a graphing calculator the 36X Pro is much less hyped. in fact, I got puzzled looks from some of the Texas Instruments reps I spoke to at NCTM when I asked about it.

TI-83 and TI-86 Emulators for Android

  UPDATE (4/27/11)  Doug contacted me to let me know has released a new version of his popular emulator app. To keep the app legal, it does not actually contain the calculators. You’ll need to find the download the ROM files separately if you want to use the calculators (kind of like the NES and other game emulators). The new app, called Andie Graph, will run ROMS for the TI-82, TI-83, TI-85, and TI-86.

Where to Sell Your Graphing Calculator

So the end of the school year (and your math class) is upon you, and you’re looking for a few extra bucks to take head out for a night on the town. Or maybe you’ve decided it’s time to ditch that old TI-83 in favor of a new color TI-Nspire CX. Or possibly you’re a parent who’s last child has finished their last math class and you’d like to recoup some of the money you invested in a graphing calculator for your kids.

Price Updates on Casio Prizm and TI-Nspire CX

Just a quick update on the pricing structure for the Casio Prizm (review) and TI-Nspire CX (review). When I was at NCTM, there was more information on both calculators and their prices. First, Casio was letting everyone know that there’s going to be a price cut on the Prizm for back-to-school this coming year. That means that around July, you should be able to find the Prizm in stores for around $99.

NCTM Lessons on Casio Prizm

As I promised at my presentations at NCTM last week, I am posting the Word files for worksheets I handed out. I know not everyone who stopped by was able to pick up a copy, especially at the second presentation, because by then the crowds had really picked up. I really appreciate everyone who took the time to listen. If you are a teacher, feel free to use these handouts with your class.

NCTM Day Four: Math Books on iPad and 3D Printing

The 2011 NCTM annual meeting is over, and I have arrived back home in Illinois. Sorry it took me a while to get this post up, but the return trip took most of Saturday. Indianapolis was a great choice for the convention. It’s so easy to move around downtown via their system of skybridges that allow you to walk for blocks at a time without ever being exposed to bad weather.

NCTM Day Three: Mario Dies, Casio Booth Hot, Nspire CX Interview

Another day has come and gone at NCTM, and frankly, I’m beat. I’ve been on my feet for the better part of two days. I’m looking forward to a little shut eye tonight. Tomorrow is a short day, so I’m planning to sleep in a little later. Today, TI talks to me about the CX, Super Mario Bros disappointments, a search for geometry books, and the Casio booth is hot.

NCTM Day Two: Battle of the Booths

Day two of the NCTM conference in Indianapolis has come and gone. For me, day two was marked by the incredible battle of the Prizm and TI-Nspire CX displays as well as learning about geometry software for the classroom and a number of cool new websites. Battle of the Booths Well if you had any doubt that Casio and Texas Instruments were taking this whole Prizm vs. Nspire CX thing seriously, one look at their booths in the exhibition hall would remove it.

NCTM Day One: Mythbusters and Flatland 3D

Day one at the annual NCTM meeting in Indianapolis is in the books. It was definitely challenging to get here as all roads leading to Indy are apparently ripped to shreds right now. It seemed like no matter what Google Maps tried to get me here, I ran into another closed road or on ramp. At one point, I even managed to end up at the Indianapolis airport, which is nowhere near the convention.
