I have run into many teachers and students who have never worked with Casio calculators (which is a shame – they are the best). Many don’t because they are mandated to use another brand or, they grew up using a specific type of calculator and don’t want to change. I myself, when teaching in Virginia, was mandated to use another brand (TI) and until I was exposed to Casio, didn’t really think about changing. But – now it makes me a little sad to still see people using the same TI models I used back in college and my first 15 years of teaching (we are talking late 80’s and 90’s) – models that haven’t changed much and are still, to this day, confusing as heck.

Therefore, I am doing what I like to consider a series of PSAs – creating a series of posts where I am going to explore the newest model of Casio graphing calculators, the fx-9750GIII, from a menu-icon approach. Casio graphing calculators are menu-driven, which is part of why they are so easy to use compared to other models. Whatever menu you choose, all the functions and tools you need are right in that menu and on the screen, easily found instead of hunting for a button somewhere on the calculator that might, or might not, give you an option you need.

For the next several blog posts, I am going to choose 2 menu icons from the fx-9750GIII graphing calculator to look at in depth. I will share a video for each within the blog post and also post just a summary of the basic functionality/purpose of the icons. By the end of the series, you will have a better understanding of most of the menu icons (most used ones), and, because of Casio’s consistency, you will also understand all of their other graphing calculator models as well!! Win-win.

Today I want to focus on the first two icons in the menu – Run Matrix and Statistics. Run-Matrix is where you do calculations of all types, from basic computations to logs, summations, integrals and matrices. You can create and save lists and matrices in Run-Matrix that can be used in other menus, such as statistics. The Statistics menu is where you enter data in the form of lists and table. You can then perform statistical calculations (one- and two-variable statistics, create regression, look at multiple types of statistical plots (scatter, pie, histogram, etc.), perform statistical tests and analyze data in several ways.

Below are two short videos – one on using the Run-Matrix menu and the other on the Statistics Menu. The goal in both videos is to give an overview of what you can do and more importantly, demonstrate how easy it is to find what you need because of the way Casio keeps everything right at your fingertips within the menu icon itself.
