A new model of graphing calculator from Casio came out recently (see press release), the fx-9750GIII. I can hear some of you asking “why, since everyone is going to mobile devices/computers and the internet?” The reality, which this pandemic has brought more to the forefront, is there is a HUGE disparity in access to digital technology and the internet, for a variety of reasons, which has made the mandated remote learning these last few months incredibly difficult for many schools districts, parents, teachers, and students. There have been several articles on just how glaring the inequities are, so I have listed a couple here:

- The Disparities in Remote Learning
- Even Before the Pandemic, Students with Limited Technology Lagged Behind Their Peers

For many students, having access to mobile devices, laptops, computers, and even the internet is not possible or is a huge struggle. Hand-held calculators are a technology tool that is a much easier and more affordable option to put into the hands of every students than any tablet or laptop. Hand-held graphing calculators can do amazing things and help students explore and discover a multitude of mathematics. Calculators are still a required tool for most schools because of access, affordability, and other mandates, such as most standardized testing situations (at least for the foreseeable future after the online-assessment debacles that occurred recently). Casio, being the better calculators on the market (compared to Texas Instruments and other options) both in functionality, cost, and ease-of-use, is still improving and updating their calculators, so the new fx-9750GIII is an example of supporting the current needs that still exist and providing hand-held technology that improves based on on those needs.* ( To be totally upfront, this is MY opinion, from over 30 years in mathematics and having been forced to use TI calculators for over 17 of those years.) *TI has a monopoly due to really good marketing and/or brainwashing, depending on how you look at it, but they are NOT a better calculator – they are hard to use or remember how to use, and let’s face it….they haven’t really changed much for years. The most popular model, the TI-84 Plus, has been around since 2004, with a slight update in 2015 to a color edition with more memory. But for the most part, the same tool for over 16 years. And still expensive. Crazy.

But I digress. Clearly don’t get me started on my TI rant!! *(Though it is partly why I am a consultant for Casio – to try to deprogram people!!)*

Back to the new updated Casio graphing calculator, the fx-9750GIII. I am going to focus my posts this week on this calculator, sharing some of the newer features, and looking at some of the menu options that are available and sharing some lessons as well. Today I just wanted to explore some of the new features of the calculator. Here’s a short list of some of the changes/additions, compared to the fx-9750GII and fx-9860GII models. Think of this new graphing calculator as a combination of these plus more.

Here is a short list of just some of the updates/changes/additions:

- Math Input/Output, Linear Input/Output AND Math Input/Mixed Output modes
- Order of Operations – clarifies entries such as 6/2(1+2) or 4π/2π (I will explore this in tomorrow’s post!!)
- New Menu Icons – e-Activity, Spreadsheet, Add-Ins: Python, Geometry, Physium, Probability Simulator (we will explore this later in the week)
- New types of regressions
- 9 new probability functions
- Ability to graph x=f(y)
- Exam Mode
- Catalog QR code
- Fraction Template Button change, Standard-Decimal Button Change, and scientific notation button change (x 10^x)
- Storage Increase (Mass Storage similar to the color graphing calculator, the fx-CG50)
- Ability to get OS updates

Its’ a crazy powerful graphing calculator. I will explore some specific functionality in later posts this week, such as probability. Today’s short video is just a quick overview of what’s there. I have also included below a link to the Quick Start Guide for those of you interested. If you want to start exploring, you can download the emulator software (which I am using in the video), which provides free access for 90-days. It’s a great way to get a feel for the tool before you decide to purchase the hand-held hardware version.
