While perusing the eduTecher website, I came upon calculator.com. Hoping to have discovered a great new online resource, I clicked on the link, but was disappointed. Calculator.com has many different types of calculators, but is pretty unprofessionally done. Many of the calculators don’t include any instructions for use. The “graphing” calculator, in particular, doesn’t seem to have any instructions, and I honestly can’t figure out how to graph an equation with it! (Granted, I wasn’t willing to invest an exorbitantly large amount of time into trying to figure it out.) And even if I could, it looks like all it can do is graph; it doesn’t seem to have any of the other many useful functions of an actual graphing calculator (like the TI-84 that my students and I use). And several of the “calculators” are really just conversion tools. I feel like this site is trying to be impressive and make it seem like it offers more functionality than it actually does…
