Big Screen Calculator
If there’s a flaw to the current generation of handheld scientific calculators on the market it’s that they are so small that it’s hard to show students how to use. The teacher either has to crowd around a calculator with a single student or work with a document camera on the big screen for the whole class. There’s a better way. Texas Instruments has just released its PC emulator for its popular line of TI-30XS and TI-24 calculators. It works with PCs and Macs and looks like a cartoon version of the calculator but all the buttons are active and the 4-line screen shows the result. The SmartView emulator costs $87, but is available on a 30-day free trial.
