Here we are again, another school year is upon us. Have you given any thought to what the best graphing calculator of 2016 is? In fact, there are many excellent choices. Casio, Texas Instruments, and HP all make great, graphing calculators. The biggest new feature of the last few years has been color. Basically, all the best graphing calculators have color displays at this point. One, the HP Prime, even has a touch screen. It's not easy to make these choices since it's a big investment for a high school student (or their parents). My advice would be to do your home work and make sure you understand what features these devices have so you can make a choice you feel good about. It will be an investment that can serve you through 4 years of math classes, or even into college.
