Casio FX-CG50 High Resolution Color Graphing Calculator, Black

It's good for doing homebrew programs with the fxsdk...I ran a clock program I wrote on it and it ran for more than 3 hours straight and the battery indicator didn't even budge from full, so the battery life is good. What with Android dying and no good handheld game consoles to buy these days, it's a good value to get your feet wet with embedded system programming. It doesn't have a sound output, but I ran the Rockbox Amiga Module player and got it to display the 4 channels on the screen as an oscilloscope in full speed....

I love my Casio Prizm! As a teacher I want a calculator that makes students think about math in new ways. I want a calculator that reinforces my lessons and looks like the math printed in a textbook. I want a calculator that makes it easy to see relationships and is intuitive to use, a tool that will grow students for years to come without having to relearn hidden menus. The students with the Casio Prizm are ahead of other students who do not have them. The calculator is really fast at graphing equations and the screen size is not compromised. The font on the calculator is large and easy to read without sacrificing the Natural Display, so everything looks the way I would expect it. The calculators' menus are all organized into folders and easy to find without needing special syntax. My favorite part is the power of the graphing feature. The equations graph very quickly, even for the most complicated equations. I can find points of interest with a single button push, even with multiple solutions. My students who have a Casio Prizm can mark points on the screen and are ahead of their peers, ready to investigate further and not having to wait for a slow graph or multiple button presses to find a point of interest. It has saved me valuable time to focus on understanding. My students benefit from it every day.
